     The present disclosure relates to a slide and pivot assembly to allow access to a process module and an interior of a processing chamber of a substrate processing system. 
     BACKGROUND 
     The background description provided here is for the purpose of generally presenting the context of the disclosure. Work of the presently named inventors, to the extent it is described in this background section, as well as aspects of the description that may not otherwise qualify as prior art at the time of filing, are neither expressly nor impliedly admitted as prior art against the present disclosure. 
     Substrate processing systems may be used to treat substrates such as semiconductor wafers. Example processes that may be performed on a substrate include, but are not limited to, chemical vapor deposition (CVD), atomic layer deposition (ALD), conductor etch, and/or other etch, deposition, or cleaning processes. A substrate may be arranged on a substrate support, such as a pedestal, an electrostatic chuck (ESC), etc. in a processing chamber of the substrate processing system. During etching, gas mixtures including one or more precursors may be introduced into the processing chamber and plasma may be used to initiate chemical reactions. 
     SUMMARY 
     A slide and pivot assembly for a process module bias assembly of a substrate processing system is provided. The slide and pivot assembly includes: a slide torsion plate; one or more rails and bearings configured to attach to the slide torsion plate or a processing chamber; a bias mounting plate configured to hold a portion of a process module for processing a substrate; and a hinge assembly attached to the slide torsion plate and the bias mounting plate. The slide torsion plate, the bias mounting plate and the hinge assembly are configured to slide via the one or more rails and bearings in a lateral direction relative to the processing chamber. The bias mounting plate is configured to pivot relative to the slide torsion plate while the slide and pivot assembly is in at least a partially pulled out state. 
     In other features, the hinge assembly includes: a first hinge member attached to the slide torsion plate; and a second hinge member attached to the bias mounting plate and connected to pivot relative to the first hinge member. The bias mounting plate and the second hinge member are configured to pivot relative to the slide torsion plate and the first hinge member while the slide and pivot assembly is in a fully pulled out state. 
     In other features, the slide and pivot assembly further includes a pin attached to the slide torsion plate. The first hinge member is configured to rotate relative to the pin to compensate for sag in the bias mounting plate. In other features, the hinge assembly includes one or more adjustment screws for adjusting a tilt angle of the first hinge member relative to the slide torsion plate. 
     In other features, the slide and pivot assembly further includes a motion interlock mechanism attached to the slide torsion plate and configured to: hold the slide torsion plate, the hinge assembly and the bias mounting plate in a pulled out state relative to the processing chamber; and permit the slide torsion plate, the hinge assembly and the bias mounting plate to be slid from a pulled out position to a pushed in position if a predetermined amount of lateral force is applied on the bias mounting plate. 
     In other features, the motion interlock mechanism is configured to: prevent the second hinge member and the bias mounting plate from pivoting relative to the first hinge member and slide torsion plate when in an engaged state; and permit the second hinge member and the bias mounting plate to pivot relative to the first hinge member and slide torsion plate when in a disengaged state. 
     In other features, the motion interlock mechanism includes: an attachment bar attached to the slide torsion plate; a latch bar; and a spring configured to rotate the latch bar relative to the attachment bar to a disengaged position when the slide torsion plate is in a pulled out state.

     DETAILED DESCRIPTION 
     A semiconductor fabrication (fab) room may include multiple tools each including multiple substrate processing stations (hereinafter referred to as “stations”). Each of the stations can be configured to perform, for example, a conductor etch process, a dielectric etch process or other substrate treatment. Space within a fab room is limited and thus the amount of space available to access each of the tools to perform, for example, service and/or maintenance on a station is limited. The stations of the tools may be arranged in a star-shaped pattern or a linear pattern. When in the star-shaped pattern, the stations are disposed around a centrally located wafer transfer module with a robot, which moves substrates from a load lock chamber to each of the substrate processing stations and back. Although this arrangement of stations provides some access space between stations, density of stations is less than the density of stations in the linear pattern. When in the linear pattern, the stations are disposed side-by-side to form two rows of stations; one row on each side of a wafer transfer module, which may operate at atmosphere or vacuum. Although the linear-shaped arrangement allows for more stations to be disposed within a dedicated space, the linear-shaped arrangement provides restricted access to sides of the stations. 
       FIGS.  1  and  2    show portions of two tools  100 ,  102  (one in solid lines at  100  and the other in dashed lines at  102 ) disposed side-by-side in a fab room. Each of tools includes two rows of stations (one row is shown for each of the tools). The stations are located adjacent to a wafer transfer module (not depicted in  FIG.  1    for clarity). There is limited space between the tools  100 ,  102 . As an example, a width W of an aisle between the tools  100 ,  102  may be small. This provides a minimal amount of space between the tools  100 ,  102  to open processing chambers of the stations and obtain access to process modules and interiors of corresponding processing chambers. 
     The examples set forth herein include slide and pivot assemblies for stations allowing process module bias assemblies of stations to be pulled out and pivoted away from corresponding processing chambers and to allow service or maintenance to be performed in the aisle. The slide and pivot assemblies are configured to repeatedly pull out from a fully docked state to a fully undocked state and accurately return the process module bias assemblies to same fully docked locations as when previously docked. As an example, the slide and pivot assemblies are able to return the process module bias assemblies to locations within ±25 micrometers (μm, referred to as microns) of the last fully docked state. The slide and pivot assemblies are configured to handle and compensate for the heavy loads of the process module bias assemblies. An example overall weight of a process module bias assembly and corresponding slide and pivot assembly is 300 kilograms (kg). The slide and pivot assemblies provide ease of use and ease of assembly. 
     The tools  100 ,  102  include: front opening unified pods (FOUPs)  104 ; an equipment front end module (EFEM) and load lock  106 ; stations with radio frequency generators  107  and gas boxes  108 ; and a power lock out and tag out system  110 . The stations further include process module bias assemblies  112 , which include respective slide and pivot assemblies, examples of which and corresponding portions thereof are shown in  FIGS.  4 - 30   . 
     Each of the stations alone or in combination may be referred to as a substrate processing system. Each of the stations may be used to etch substrates using, for example, radio frequency (RF) plasma. Each station includes a processing chamber, such as an inductive coupled plasma (ICP) chamber or a conductive coupled plasma (CCP) chamber. The stations may, for example, perform conductive etch or dielectric etch processes. 
       FIG.  2    shows a portion of one of the tools  100 ,  102  of  FIG.  1   . The tool includes the FOUPs  104 , the EFEM and load lock  106 , the stations  109 , and the power lock out and tag out system  110 . The tool has an overall footprint  220 . The tool further includes a wafer transfer module  222  for transferring substrates to and from the stations  109 . The wafer transfer module  222  may include robots  224 ,  226  and a buffer  228  for temporary storage of wafers. The robots  224 ,  226  transfer wafers to and from the stations  109  and the buffer  228 . Although positioned between robot  224  and robot  226  in  FIG.  2   , buffer  228  may be positioned anywhere in wafer transfer module  222 . In other embodiments, the buffer  228  may be positioned outside wafer transfer module  222  (e.g., coupled to stations  109  or load lock  106 ). 
       FIG.  3    shows a portion of one of the tools  100 ,  102  of  FIG.  1   . The tool includes the FOUPs  104 , the EFEM and load lock  106 , the stations  109 , and the power lock out and tag out system  110 . The stations include the RF generators and gas boxes (collectively referred designated  300 ) and the process module bias assemblies with slide and pivot assemblies  112 . The RF generators may provide RF power to electrodes in substrate supports of the stations. The gas boxes supply gases to processing chambers of the stations. The wafer transfer module  222  is also shown. 
     Substrates scheduled to be loaded and processed are stored in the FOUP  104 . The substrates are transferred from the FOUP  104  to the stations  109  via the EFEM and load lock  106  via respective loading ports  302 . The RF generators and gas boxes  300  are arranged above the stations  109  and supply RF power and process gases to process modules of the stations  109 . 
       FIG.  4    shows a substrate processing station  400  (including a slide and pivot assembly  402 ), which is an example of one of the stations  109  of  FIGS.  2 - 3   . The slide and pivot assembly  402  is connected to a processing chamber  404  and a process module bias assembly  406 . The slide and pivot assembly  402  allows the process module bias assembly  406  to be pulled out away from the processing chamber  404  and pivoted up to a predetermined angle relative to a front face of the processing chamber  404 . The process module bias assembly  406  includes a housing  408 , a portion  410  of a process module including a process bias bowl  412 . The process module may include, in addition to the process bias bowl  412 , an electrostatic chuck and/or other substrate support, and a top plate assembly, examples of which are shown in  FIG.  6   . 
     The example width W of an aisle between the station  400  and an opposing station is shown to illustrate that the process module bias assembly  406  is able to be pulled out and pivoted within the aisle. This provides a clear open space  414  on a right side of the slide and pivot assembly  402  for a technician to access the process bias bowl  412  and an interior of the processing chamber  404  for service and maintenance purposes including wet cleaning. The process bias bowl  412  and an interior of the processing chamber  404  are accessed from a right side of the process module bias assembly  406  without interference. For example, no slides, rails and/or other components are in the open space  414  and/or interfere with a technician accessing the interior of processing chamber  404 . Although the process module and bias assembly  406  is shown pivoting to the left, the slide and pivot assembly may be configured and mounted on the right side of the processing chamber such that the process module and bias assembly pull out and pivot to the right relative to the processing chamber. 
       FIGS.  5  and  6    show a substrate processing system  500  illustrating a slide and pivot assembly  502  in a fully docked state  504  and in a fully undocked state  506 . The substrate processing system  500  includes a vertical arrangement of a RF generator and gas box  508 , a top plate assembly  509 , a processing chamber  512 , and a turbo pump  513  for evacuating the processing chamber  512 . The processing chamber  512  sits on a stand  510  and includes a process module bias assembly  514 . The process module bias assembly  514  includes a housing  516  and a process module bias bowl  518  attached to a bias mounting plate  520  of the slide and pivot assembly  502 . A portion  521  of a substrate support, such as an electrostatic chuck (ESC), is shown coupled to the process bias bowl  518 . The top plate assembly  509  is shown on the processing chamber  512 . The process module bias assembly  514  includes circuits for supplying RF and/or bias power to electrodes of the substrate support and/or power to heater elements of the substrate support and may include coolant channels for supplying coolant to cool the substrate support. During operation, a substrate is received from a backside of the processing chamber  512  via an access port  522  and arranged on the substrate support. 
     The slide and pivot assembly  502  is attached to a wall of the processing chamber  512  and is configured to hold the weight of the process module bias assembly  514 , which includes the weight of the slide and pivot assembly for a total assembly mass of, for example 300 kg. The slide and pivot assembly  502  is configured to handle more than a predetermined minimum number of undocking, redocking, opening and closing cycles per year (e.g., 100 cycles per year) for a predetermined number of minimum years (e.g., 10 years). The slide and pivot assembly is configured to provide a repeatable closed and fully docked position. The slide and pivot assembly is configured to be within, for example, 25 μm of an initial closed and fully docked position each time the corresponding processing chamber is opened and then returned to a closed state. This allows for repeatable undocking and redocking without need for recalibration of parameters associated with a location of the substrate support. 
       FIGS.  7  and  8    show a process module bias assembly  600  illustrating a fully pulled out and non-rotated state  602  and pivot angle of rotation associated with the fully undocked state  604 . The fully pulled out and non-rotated state  602  is an interim state between the fully docked and fully undocked states. The fully undocked state  604  refers to when the process module bias assembly  600  is fully rotated, such that the housing  606  and process module bias bowl  608  are fully pivoted away from the processing chamber  610 . While in a fully undocked state, a technician  708  is able to access the interior of the processing chamber  610  as shown while in a standing and/or kneeling position. The process module bias assembly  600  may have a predetermined maximum slide force F 1  that may have a unit of measure of pound-force (lbf) and a predetermined maximum pivot (or rotational) force F 2 , which may also be measured unit of measure of lbf. 
       FIG.  9    shows a portion  800  of a processing chamber  802  including a process module bias assembly  805  (shown in  FIG.  10   ) having a slide and pivot assembly  806 . The processing chamber  802  and the slide and pivot assembly  800  may be implemented in any of the above-stated stations and have similar aspects as any of the above-stated processing chambers and slide and pivot assemblies. The slide and pivot assembly  806  includes a slide torsion plate  808 , a hinge assembly  810  and a bias mounting plate  812 . A pivot lock assembly  814  is shown attached to the hinge assembly  810 . The pivot lock assembly  814  as further described below locks the bias mounting plate  812  in a non-pivoted state and in a fully pivoted state. The bias mounting plate  812  has bias bowl mounting features. 
     The slide and pivot assembly  806  is shown in an interim pivot state between the non-pivoted state and the fully pivoted state. The slide pivot assembly  806  is shown at an 80° pivot angle relative to the front sidewall  902  of the processing chamber  802 . This may be a worse case bearing load position for bearings of bearing blocks of the slide and pivot assembly  806 . The bearing blocks are shown in  FIG.  14   . The slide torsion plate  808  handles the offset load and works in torsion to support the load. The slide torsion plate  808  provides stiffness to support the cantilevered load of the bias assembly weight, and limits deflections both in the vertical and twist directions. The resulting structure is more space efficient than a design using larger rails without a torsion plate, thus allowing for shorter spacing between processing chambers, and resulting in a smaller system footprint. 
       FIG.  10    shows a portion  1000  of a processing chamber  802  and the corresponding process module bias assembly  805  including the slide and pivot assembly  806  of  FIG.  9   . The process module bias assembly  805  includes a housing  1002 . A pivot lock actuator  1004  allows the housing  1002  along with the bias mounting plate  812  to be secured to processing chamber  802 , or released and pivoted away from the processing chamber  802 . The bias mounting plate  812  is attached to a backside of the housing  1002 . The pivot lock actuator  1004  may be a “pull-tab” that pulls a cable in a cable assembly (shown in  FIG.  12   ) to release a pivot lock plunger of the pivot lock assembly  814 . The slide and pivot assembly  806  includes a slide lock assembly  1001  with a slide lock  1003  shown in a locked state while the slide and pivot assembly  806  is in a fully docked state. A slide lock actuator  1006  allows the housing  1002  along with the bias mounting plate  812  to slide in a horizontal linear manner away from the processing chamber  802 . The slide lock actuator  1006  may be a “pull-knob” that pulls a cable in a cable assembly  1008  to release a slide lock plunger of the slide lock assembly  1001 . Alternatively, the slide lock plunger could be actuated by electric or pneumatic control. The pivot lock plunger of the pivot lock assembly  814  may also alternatively be actuated by electric or pneumatic control. 
       FIG.  11    shows a portion  1100  of the processing chamber  802  and the corresponding process module bias assembly  805  including the slide and pivot assembly  806  illustrating the slide lock  1003  locked in a fully pulled out state. The slide and pivot assembly  806  includes the slide torsion plate  808  and the hinge assembly  810 . The slide lock  1003  includes a plunger  1102  and wheel  1104  that is pushed into notches (one notch  1106  is shown) in the slide torsion plate  808  for different slide lock states of the slide and pivot assembly  806 . The wheel  1104  spins on a pin  1107 . Process module bias assembly devices and components  1110  are disposed in the housing  1002  and may include RF sources, bias voltage sources, power sources, power cables, conductive lines, coolant lines, gas lines, etc. This may include a pull handle  1112  for pulling out the process module bias assembly  805 . 
       FIG.  12    shows the slide and pivot assembly  806  including the slide torsion plate  808 , the hinge assembly  810  and the bias mounting plate  812 , but not including housing  1002 . The hinge assembly  810  is released from locked states by the pivot lock actuator  1004  of the pivot lock assembly  814 . The pivot lock actuator  1004  is connected to a pivot lock plunger  1210  via a cable of a cable assembly  1212 . 
     The bias mounting plate  812  is fastened to the front of the processing chamber  802  via one or more closure fasteners (e.g., bolts or screws)  1216  (shown in  FIG.  26   ), which extends through one or more slots or holes  1218  in the bias mounting plate  812 . The closure fasteners  1216  are attached after the slide and pivot assembly  806  is returned to a closed fully retracted (or fully docked) state. 
     The slide and pivot assembly  806  may include a jack screw assembly  1220  including a jack screw block  1222 , block fasteners  1224 , and a jack screw  1226 . Elements of the jack screw assembly  1220  are also shown in  FIGS.  18 - 19   . The jack screw block  1222  includes slots  1223  and slides on the block fasteners  1224  between an IN position and an OUT position. In some embodiments, the IN position is the default position. The jack screw block  1222  is shown in the IN position in  FIG.  18   . The block fasteners  1224  are shoulder screws, which may not clamp down the jack screw block  1222 . In an embodiment, the jack screw block  1222  is free to fall under its own weight at all times. due to the weight of the jack screw block  1222 . The jack screw  1226  extends through the bias mounting plate  812  and is fastened to a front wall  1225  of the processing chamber  802 . While the jack screw block  1222  is in the IN position, the jack screw  1226  is able to be fastened to (or screwed into) the wall  1225  of the processing chamber  802 . While in the OUT position, the jack screw  1226  is able to be CCW rotated (or partially unscrewed) to move out from the front wall  1225  and push pressure on the jack screw block  1222  to disengage one or more alignment pins, such as alignment pin  1244 . 
     The pivot lock assembly  814  includes a block  1230 , which is attached to the hinge assembly  810 , the plunger  1210 , a bracket  1232 , and a spring  1234 . The bracket  1232  holds the cable assembly  1212  for the plunger  1210  in place relative to the block  1230 . A portion of the pivot lock assembly  814  is shown in  FIG.  17   . 
     The bias mounting plate  812  may include one or more holes for alignment pins. Two holes  1240 ,  1246  and the alignment pins  1242 ,  1244  are shown. An example of an alignment pin is shown in  FIG.  27   . The alignment pins  1242 ,  1244  are used to align the bias mounting plate  812  relative to the processing chamber  802  when docking the slide and pivot assembly  806 . The alignment pins  1242 ,  1244  may be mounted on the processing chamber  802  and corresponding bushings may be mounted on the bias mounting plate  812 . In one embodiment, the alignment pins  1242 ,  1244  are mounted on the bias mounting plate  812  and the corresponding bushings are mounted on the processing chamber  802 . The jack screw  1226  may be used to move the bias mounting plate  812  ON and OFF of the alignment pins  1242 ,  1244 . The jack screw  1226  may be tightened to, for example, insert ends of the alignment pins  1242 ,  1244  in the corresponding bushings in the bias mounting plate  812 . The jack screw may not be torqued down, but rather simply used to engage alignment pins with corresponding bushings. The above-stated closure fasteners are used to close a gap between the bias mounting plate  812  and the processing chamber  802  after the alignment pins are inserted at least partially into the bushings via the jack screw  1226 . Operation of the jack screw assembly  1220  is further described below with respect to  FIGS.  18 - 19   . 
       FIG.  13    shows the slide torsion plate  808  and an adjustable hinge assembly  810  for the slide and pivot assembly  806  of  FIG.  9   . The slide and pivot assembly  806  includes the slide torsion plate  808  and the hinge assembly  810 . The slide lock actuator  1006  actuates the slide lock plunger  1102 . The pivot lock actuator  1004  releases the plunger  1210  of the pivot lock assembly  814 . 
     The hinge assembly  810  includes a slide torsion plate member  1300  and a bias mounting plate member  1302 . The members  1300 ,  1302  (also referred to as hinge members) are “U-shaped”. The slide torsion plate member  1300  is connected to a front edge of the slide torsion plate  808  via fasteners (e.g., bolts or screws)  1304 , and pivots on an alignment pin that is fixed to the torsion plate. The bias mounting plate member  1302  is attached to one end of the bias mounting plate  812  (shown in  FIG.  12   ) via fasteners (e.g., bolts or screws)  1306  (one of which is not shown). The bias mounting plate member  1302  is attached and pivots relative to the slide torsion plate member  1300  via fasteners, such as central pivot members and/or fasteners  1308 ; other central pivot members are shown in  FIGS.  24 - 25   . A tilt angle of the hinge assembly  810  relative to the slide torsion plate  808  may be adjusted via fasteners (e.g., bolts or screws)  1310  (may be referred to as hinge adjustment fasteners). The tilt angle may be adjusted to compensate for sag due to the weight of the process module biasing assembly and slide and pivot assembly  806 . An example sag angle is shown in  FIG.  26   . The bias mounting plate  812  may rotate clockwise due to the weight the process module biasing assembly and slide and pivot assembly  806  when pulled out away from the processing chamber  802 . This twists the slide torsion plate  808 . The fasteners  1310  may be turned in or out to rotate the bias mounting plate  812  in a CCW manner relative to a pivot point (represented by pivot point  1312  and CCW rotation arrow  1314  in  FIG.  26   ) to compensate for the clockwise sag. 
     Referring now to  FIGS.  12  and  14   , which shows a portion  1400  of the slide torsion plate  808 , a guide rail system including guide rails  1402  and bearing blocks  1404 , the slide and pivot assembly  806 , the pivot lock assembly  814 , and the slide lock assembly  1001 . The guide rails  1402  are attached to an inner side of the slide torsion plate  808 . In an embodiment, the guide rails  1402  are implemented as profile ball rails. The pivot lock assembly  814  includes the pivot plunger  1210 , the cable assembly  1212  and pivot lock actuator  1004 . The slide lock assembly  1001  includes the slide plunger  1102 , the cable assembly  1008  and slide lock actuator  1006 . The bearing blocks  1404  include bearings (e.g., ball bearings) that ride in grooves  1406  of the guide rails  1402 . The grooves are on both top and bottom sides of the guide rails  1402 . The bearing blocks  1404  are fastened to a sidewall of a processing chamber (e.g., the processing chamber  802  of  FIG.  9   ) via fasteners that extend through holes in the bearing blocks  1404 . When actuated, the slide torsion plate  808  and guide rails  1402  are moved relative to the bearing blocks  1404 . 
     The guide rail system has high load capacity, low friction and is able to handle a large amount of weight. The load range of the guide rail system is the same for both pulling out and retracting the slide torsion plate  808 . Although the rails  1402  are shown as being mounted on the slide torsion plate  808  and the bearing blocks  1404  are shown as being mounted on a processing chamber wall, the slide torsion plate  808  may be mounted on the processing chamber wall and the bearing blocks  1404  may be mounted on the slide torsion plate  808 . Mounting the bearing blocks  1404  on the processing chamber wall is done for decreasing sag, because the distances from the bearing blocks  1404  to the load center of mass decrease as the slide and pivot assembly is pushed in and closed, resulting in a shorter lever arm and reduced sag effect. 
     A slide stop block  1420  may be attached to the sidewall of the processing chamber  802  and limit movement of the slide torsion plate  808  along the guide rails  1402 . A corresponding stopping member  1422  may be fastened to the slide torsion plate  808  and be against the slide stop block  1420  depending on the state of the slide and pivot assembly  806 . The slide stop block  1420  may be in contact with the stopping member  1422  when in, for example, a fully pulled out (or open) state. An additional slide stop block and an additional stopping member may be provided for the fully docked (or closed) state. The slide stop blocks  1420  and stopping member  1422  may include dampers. Example dampers are shown as round disks  1425  in  FIG.  13   . Other dampers may be utilized. 
       FIG.  15    shows the slide torsion plate  808 , guide rails  1402 , bearing blocks  1404 , and slide lock assembly  1001  of  FIG.  9 - 14   . The guide rails  1402  are attached to the inside of the slide torsion plate  808 . The bearing blocks  1404  ride on the guide rails  1402 . The slide lock assembly  1001  includes the plunger  1210  and the bracket  1232 , as well as a plunger housing  1500 . 
       FIG.  16    shows a slide lock assembly  1600 , which is attached to the processing chamber  802  and is an example of the slide lock assembly  1001  of  FIG.  11   . The slide lock assembly  1600  includes a slide lock housing  1601 , the plunger  1102  and wheel  1104  that extends into notches in the slide torsion plate  808 . A bracket  1602  is attached to the housing  1601  and holds the cable assembly  1008  relative to the housing  1601 . 
       FIG.  17    shows the pivot lock assembly  814 , which is attached to the bias mounting plate member  1302  of the hinge assembly  810 . The hinge assembly  810  also includes the slide torsion plate member  1300 , which is attached to the slide torsion plate  808 . The hinge assembly  810  includes the fastener  1308 , or other central pivot member, such as a pivot shaft or pin. Two locking positions for the plunger  1210  are shown and represented by channels  1700 ,  1702  in a pivot block  1704  attached to the slide torsion plate member  1300 . The plunger  1210  is shown in the channel  1700 , which is associated with the non-rotated state. The plunger  1210  may be pulled out of the channel  1700  and the bias mounting plate member  1302  may be rotated clockwise (CW) about the fastener  1308  and the plunger  1210  may then extend into the channel  1702 . The channel  1702  is associated with the open (or fully rotated) position. The bias mounting plate member  1302  pivots to a fully open position at which the pivot lock plunger  1210  engages the channel  1702 , referred to as a service position. The pivot lock plunger may be actuated by a pull cable (as shown in  FIG.  13   ), or by electric or pneumatic control. 
       FIGS.  18 - 19    show the jack screw assembly  1220  including the jack screw block  1222 , block fasteners  1224 , and jack screw  1226 . The jack screw block  1222  includes the slots  1223  and slides on the block fasteners  1224  between the IN and OUT positions. The IN and OUT positions correspond respectively to (i) the jack screw  1226  extending through the bias mounting plate  812  and fastening to the processing chamber  802 , and (ii) the jack screw  1226  being used as a jack to release the bias mounting plate  812  from the processing chamber  802 . While in the IN position, the head of the jack screw  1226  is able to extend into the jack screw block  1222  further than when in the OUT position. The jack screw  1226  includes a screw head  1800 , a stem  1801 , a screw head wear cap  1802  and a washer  1804 . The jack screw block  1222  includes a stopper  1810  for the OUT position. The screw head wear cap  1802  is pressed against the stopper  1810  when the jack screw block  1222  is in the out position and the jack screw  1226  is being used to release the alignment pins from the corresponding bushings as described above. The stopper  1810  is a solid integral portion of the jack screw block  1222  that prevents the head  1800  of the jack screw  1226  from being moved into the jack screw block  1222 . The stem  1801  may be threaded and be screwed into a threaded bushing  1812  inserted in the processing chamber wall  1814 . Another jack screw assembly example is further shown in  FIGS.  44 - 46   . In an alternative embodiment, the screw head wear cap  1802  is not included and instead a wear element is inserted in the block OUT position covering a screw head contact area (i.e. stopper area) of the jack screw block  1222 . In yet another alternative embodiment, the screw head wear cap  1802  is not included and the jack screw block  1222  is formed of a low friction low wear material. A similar example is shown in  FIGS.  40 - 43   . This embodiment utilizes a self-retaining wear cap with stepped washer, both of a low friction and low wear material. 
       FIGS.  20 - 23    show a portion  2000  of the slide and pivot assembly  806  including the slide torsion plate  808 , hinge assembly  810  and a slide-pivot interlock mechanism  2002 . The slide-pivot interlock mechanism  2002  is used to hold the slide and pivot assembly in the fully pulled out state. The slide-pivot interlock mechanism  2002  prevents accidental damage to the corresponding process module bias assembly and/or processing chamber by, for example, a user attempting to dock the bias assembly when the corresponding bias mounting plate is not in a fully non-rotated position. The slide-pivot interlock mechanism  2002  also, for example, prevents pivot motion towards the fully non-rotated position unless the slide is in the fully extended pulled out/open position. 
     The slide-pivot interlock mechanism  2002  includes an attachment bar  2003 , a latch bar  2004 , a spring (example of a torsion spring is shown in  FIGS.  34 - 35   ), a stop strip  2008 , an adjustable catch bracket  2010 , and a toggle stop bracket  2012 . The spring may be a torsion spring or a spring of a different type or may be located away from the latch bar center of rotation. When in a fully pulled out state, a bearing roller  2014  on the latch bar  2004  is moved relative to and past the stop strip  2008  and allows the spring to rotate the latch bar  2004  releasing a hooked end  2016  of the latch bar  2004  from the adjustable catch bracket  2010 . In an alternate embodiment, the function of the attachment bar  2003  is made an integral part of the torsion plate  808 , and the torsion spring function can be achieved using an extension or compression spring. 
     The torsion spring is disposed between the attachment bar  2003  and the latch bar  2004  and coiled around a torsion pin  2018 . The latch bar  2004  includes two slots  2020  corresponding to a pair of pins  2022 . The latch bar  2004  rotational limits are defined by movement of the pins  2022  in the slots  2020 . An end  2024  of the stop strip  2008  is angled to allow the bearing roller  2014  to roll along the end  2024 . The end  2024  may be angled such that the slide and pivot assembly  806  remains in the fully pulled out state and unless a predetermined amount of lateral force is applied on the process module bias assembly to push in the slide and pivot assembly  806  to a fully pushed in state. When the predetermined amount of force is applied, the bearing roller  2014  rotates causing the latch bar  2004  to rotate against the force of the torsion spring and hook the hooked end  2016  on the adjustable catch bracket  2010 . A pull cable or other actuation device may be used to pivot the latch bar  2004  into the closing state, or the latch bar may be pivoted into the closing state by pushing on it directly by hand. This would allow a square end, or reverse angle, on the stop strip for a more positive slide lock in the open position. 
     The adjustable catch bracket  2010  has screws  2030 ,  2032  to adjust position of the catch bracket  2010  in respective directions relative to the bias mounting plate member  1302 . The latch bar  2004  includes a latch bar stop element  2034 , which is used to prevent rotation of the latch bar  2004  while the bias mounting plate member  1302  is rotated away from a fully closed (or 90°) state relative to the slide torsion plate member  1300 , as shown in  FIG.  23   . The latch bar stop element  2034  may be implemented as a pin, a flange, a cut-down semi-circular pin or other part, or other stop element. The toggle stop bracket  2012 , which is mounted on the slide torsion plate member  1300 , contacts the latch bar stop element  2034  and prevents the latch bar  2004  from rotating into the closed position, except when the hinge is in the fully non-rotated position. 
     The toggle stop bracket  2012  has multiple “L-shaped” portions and is able to slide relative to the slide torsion plate hinge member  1300  along a notch  2040  in a spring holding block  2042 , and guide pins in hinge member  1300 . The spring holding block  2042  holds a spring  2044  that slides the toggle stop bracket  2012  towards the bias mounting plate member  1302 . As the bias mounting plate member  1302  is pivoted open and away from the slide torsion plate member  1300 , the toggle stop bracket  2012  slides to the position shown in  FIG.  23    to stop rotation of the latch bar  2004 . As the bias mounting plate member  1302  is pivoted closed towards the slide torsion plate member  1300 , the toggle stop bracket  2012  slides in an opposite direction to no longer be in contact with the latch bar stop element  2034 , which allows the hooked end  2016  to engage a hooked end  2050  of the adjustable catch bracket  2010 . An alternative embodiment is illustrated in  FIGS.  36 - 39   . 
       FIGS.  24 - 25    show an example of a bearing assembly  2500  for a hinge assembly, such as the hinge assembly  810  of  FIG.  9   . Although a particular bearing assembly is shown, other bearing assemblies may be used. Two of the bearing assembly  2500  may be used for both ends of the hinge assembly  810 . The hinge assembly  810  includes the members  1300 ,  1302 . The bearing assembly  2500  includes a pin  2502  that extends through holes  2504 ,  2506  in the members  1300 ,  1302 , a thrust bearing  2508 , a tapered roller bearing assembly  2510 , a washer  2512  and a lock nut  2514 . The roller bearing assembly  2510  includes an outer cup  2516 , containing tapered roller hinge pivot bearings  2518  and an inner cone  2520 . The roller bearing assembly  1510  sits in a pocket  2530  of the bias mounting plate member  1302 . 
     The tapered roller bearing assembly  2510  improves bias alignment and repeatability, as compared with a simple sleeve bearing assembly. The tapered bearing eliminates clearance between hinge member  1302  and pivot shaft  2502 . Bearing clearance contributes to position error during and after the hinge tilt adjustment procedure to compensate for bias mounting plate sag angle ( FIG.  26   ). One of the above disclosed alignment pins (e.g., the pin  2904  of  FIG.  28   ) may be referred to as a clocking alignment pin, which serves to properly align the bias mounting plate angle. When bearing clearance related position error is small and negligible, the clocking pin requirement may be removed. Clocking pin removal eases docking and fastening the bias mounting plate  812  to the processing chamber  802  of  FIG.  9   . 
     As an alternative to the bearing assembly of  FIGS.  24 - 25   , a sleeve or needle bearing assembly may be used. The alternate bearing assembly may include a fastener, such as a pin, which extends through nuts, thrust bearings, a thrust washer, sleeve bushings and holes in the members  1300 ,  1302 . The sleeve bushings may extend out of the holes and include washer-shaped ends, designated  2060  in  FIGS.  20  and  21   . As an example, the sleeve bushings may be steel backed and/or polytetrafluorethylene (PTFE) sleeve bushings. 
       FIG.  26    shows the slide and pivot assembly  806  including the hinge assembly  810  and the bias mounting plate  812 . Due to weight of the corresponding process module bias assembly and the slide and pivot assembly  806 , sag can occur and is illustrated as an example sag angle. An alignment pin  2710  is shown in an opening  2712  of the bias mounting plate  812 .  FIG.  30    shows how the hinge assembly  810  is adjusted to account for this sag angle using the hinge adjustment fasteners  1310  of  FIG.  13   . 
       FIG.  27    shows an alignment pin  2800  and receiving bushing  2802 . The alignment pin  2800  is shown in the chamber wall  1814 . The receiving bushing  2802  is shown in the bias mounting plate  812 . The alignment pin  2800  has a tapered end  2804  and allows for easy alignment and insertion of the alignment pin  2800  in a hole  2806  of the bushing  2802 . The bushing  2802  has a rounded end  2807  for ease in sliding the alignment pin  2800  into the bushing  2802 . This aligns the bias mounting plate  812  relative to the processing chamber  802  of  FIG.  9   , prior to tightening closure fasteners, such as fastener (e.g., bolt or screw)  1216  of  FIG.  26   . In an embodiment, 4 closure fasteners are used to fasten the bias mounting plate  812  to the processing chamber  802 . As an example, the bushing  2802  provides up to 30 microns of pin clearance relative to the bushing  2802 . In an embodiment, the alignment pin  2800  is on the bias mounting plate  812  and the bushing  2802  is on the chamber wall  1814 . 
       FIG.  28    shows a portion  2900  of the processing chamber  802  of  FIG.  9    including the bias plate with alignment pins  2902 ,  2904 . In  FIG.  28   , the bias mounting plate member  1302  of the hinge assembly  810  is not shown as being attached to the bias mounting plate  812  and is rotated away from the processing chamber  802 . The alignment pin  2904  may be referred to as a clocking alignment pin. In one embodiment, the clocking alignment pin  2904  is not included to ease attachment of the bias mounting plate  812  of  FIG.  9    to the processing chamber  802 , and to ease the hinge tilt adjustment procedure used to align the bushings and pins. 
       FIGS.  29  and  30    show a hinge assembly  3000  similar to the hinge assembly  810  of  FIG.  9   . The hinge assembly  3000  includes the members  1300 ,  1302  attached to the plates  808 ,  812 . The hinge assembly  3000  includes a tilt adjustment screw  3001 , a tilt lock screw  3002 , or in an alternate embodiment, eccentric tilt adjustment bushings  3004 . The slide torsion plate member  1300  is rotatable about a rotation pin  3006  attached to the slide torsion plate  808 . The hinge assembly  810  is shown with different hinge pivot fasteners  3010  than in the previous figures associated with the embodiment of  FIG.  9   . 
     The tilt adjustment screw  3001  and/or the tilt lock screw  3002  may be turned to tilt the bias mounting plate CCW to compensate for sag and negate slide plate twist. This may be done while under load. Arrows  3012  represent CCW rotation of the slide torsion plate member  1300  about the pin  3006  and corresponding CCW motion of the hinge assembly  3000  and bias mounting plate  812 . Hinge fasteners (e.g., bolts or screws)  3020  are included and tightened down after the tilt adjustment screw  3001  has been adjusted. 
       FIGS.  31 - 33    show a portion  3200  of another slide and pivot assembly including a slide torsion plate  3202 , a hinge assembly  3204 , an attachment bar  3208 , and a latch bar  3210 . The hinge assembly  3204  includes a slide torsion plate member  3212  and a bias mounting plate member  3214  that is attached to a bias mounting plate. The latch bar  3210  operates similarly as the latch bar  2004  of  FIG.  20    and is held in a fully pulled out state by a stop strip  3216 . The latch bar  3210  includes a hooked end  3218  that when engaged is at least partially in a slot  3219  of a catch bracket  3220 , which is attached to the bias mounting plate member  3214 . 
       FIGS.  34 - 35    show a portion  3500  of the slide and hinge assembly  3204  of  FIG.  31    illustrating a torsion spring  3502 , which is around a rotation pin  3504  and has ends pressed against holding pins  3506 ,  3508  attached to the latch bar  3210  and the attachment bar  3208 . The torsion spring  3502  rotates the latch bar CCW when a bearing roller  3520  clears the stop strip  3216 . In an alternate embodiment, an extension spring or other type of spring is utilized to apply rotation force at some distance from the latch bar pivot point. Alternately, the latch bar  3210  can be moved manually without using a spring. 
       FIGS.  36 - 39    show portions  3700 ,  3800 ,  3900 ,  4000  of the hinge assembly  3204  of the slide and pivot assembly of  FIG.  31   .  FIG.  36    illustrates the slide and pivot assembly in a non-rotated state with the latch bar  3210  engaged.  FIG.  37    illustrates a pivoted state with the latch bar  3210  disengaged.  FIG.  38    illustrates a non-rotated state with the latch bar  3210  engaged.  FIG.  39    illustrates a pivoted state with latch bar disengaged. 
     The hinge assembly  3204  includes the members  3212 ,  3214 , the latch bar  3210 , the catch bracket  3220 , and a toggle stop bracket  3702  that is held by and slides relative to a holding block  3704  and is moved by a spring  3706 . The latch bar  3210  includes an adjustable second toggle stop bracket  3707  that is “L-shaped” and includes an end  3709  that is against a tab  3711  of the toggle stop bracket  3702  when the bias mounting plate member  3214  is in an open state as shown in  FIGS.  37  and  39    and is alongside of the tab  3711  when the bias mounting plate member  3214  is in a fully non-rotated state as shown in  FIGS.  36  and  38   . A position of the toggle stop bracket  3707  is adjusted relative to the latch bar  3210  via a fastener  3713 . 
       FIGS.  40 - 43    show a jack screw assembly  4200  illustrating a jack screw block  4202  in ON (IN) and OFF (OUT) positions and a jack screw  4204  in a fastened and pulled out states. The jack screw assembly  4200  is configured to and functions similar to the jack screw assembly of  FIGS.  18 - 19   . The jack screw block  4202  is attached to a bias mounting plate  4218  via fasteners, such as fasteners  1224  of  FIG.  19   . The fasteners  1224  retain the jack screw block  4202  and allow adequate clearance for the jack screw block  4202  to slide due to weight of the jack screw block  4202 . The jack screw block  4202  includes an upper cupped area  4208  to receive a head  4210  of the jack screw  4204  when in a pulled out state. The jack screw block  4202  also includes a solid area  4212  below the upper cupped area  4208 , which does not receive the head  4210  of the jack screw  4204 , but rather is used to jack the bias mounting plate  4218  off of a processing chamber wall  4220 . 
     The head  4210  may be covered by a head screw cap  4230  having hooked fingers  4232 , which prevent the head screw cap from coming off the head  4210 . The jack screw  4204  may include a stepped washer  4234  and a non-stepped washer  4236 . The stepped washer  4234  includes a protruding ring-shaped portion  4238  that is inserted in an opening of the head screw cap  4230  when on the head  4210 , and functions to direct clamping forces to the head  4210  and not to the hooked fingers  4232 . 
       FIGS.  44 - 46    show a jack screw assembly  4400  illustrating a jack screw block  4402  and a jack screw  4404  in a fastened state. The jack screw assembly  4400  is configured to and functions similar to the other jack screw assemblies disclosed herein. The jack screw block  4402  is attached to a bias mounting plate  4406  via fasteners, such as fasteners  1224  of  FIG.  19   . The jack screw block  4402  includes an upper cupped area  4408  to receive a head  4410  of the jack screw  4404  when in a pulled out state. The jack screw block  4402  also includes a hollow recessed area  4412  below the upper cupped area  4408 , which does not receive the head  4410  of the jack screw  4404 , but rather is used to jack the bias mounting plate  4406  off of a processing chamber wall  4413 . The hollow recessed area  4412  is configured to hold a wear component  4414 . As an example, the wear component  4414  may be a plastic bushing. Pressure is applied in a backside of the wear component  4414  when the jack screw  4404  is rotated CCW to jack the bias mounting plate  4406  off the processing chamber wall  4413 . The wear component  4414  is replaceable similar to the head screw cap  4230  of  FIG.  43   . 
     The following  FIGS.  47 - 50  and  53 - 63    illustrate alternative example embodiments that may replace any of the above-described slide and pivot assemblies and/or portions thereof. 
       FIGS.  47 - 48    show a processing chamber  4700  including a portion  4701  of another slide and pivot assembly including cam followers  4702 . The cam followers (or rollers)  4702  are attached within channels  4704  formed by the mounting brackets  4706  and a sidewall  4710  of the processing chamber  4700 . Fasteners  4708  may extend through the mounting brackets  4706  and through the cam followers  4702  and are threaded into the sidewall  4710  of the processing chamber  4700 . The fasteners  4708  attach the cam followers  4702  to the sidewall  4710 . Additional fasteners may be included to attach the mounting brackets  4706  to the sidewall  4710 . The cam followers  4702  may include bearings. Intermediary spacers (or rails)  4712  may be attached to the slide torsion plate  4720  or integrally formed as part of the slide torsion plate  4720 . The intermediary spacers  4712  are disposed between top and bottom edges  4714 ,  4716  of the torsion plate  4720 . The brackets  4706  may be ‘L’-shaped and keep a portion of the torsion plate  4720  between the cam followers  4702 . 
     The torsion plate  4720  has a ‘T’-shaped cross-section and includes a first portion disposed between the intermediary spacers  4712  and a second portion disposed between the mounting brackets  4706 . The intermediary spacers  4712  may be integrally formed as part of or be attached to the torsion plate  4720 . The torsion plate  4720  and intermediary spacers  4712  slide between the cam followers  4702 . The brackets  4706  and intermediary spacers  4712  and may be formed of steel. The torsion plate  4902  may be formed of aluminum. 
       FIGS.  49 - 50    show a processing chamber  4900  including a portion  4901  of another slide and pivot assembly including torsion plate  4902  with tracks  4904  for ‘V’-grooved cam followers (or track rollers)  4906 . The torsion plate  4902  slides on the track rollers  4906 . The track rollers  4906  are attached within channels  4908  formed by mounting brackets  4910  and a sidewall  4912  of the processing chamber  4900 . Fasteners  4914  may extend through the mounting brackets  4910  and through the track rollers  4906  and are threaded into the sidewall  4912 . The fasteners  4914  attach the track rollers  4906  to the sidewall  4912 . Additional fasteners may be included to attach the mounting brackets  4910  to the sidewall  4912 . The track rollers  4906  may include bearings. The brackets  4910  may be ‘L’-shaped to help keep the tracks  4904  in the ‘V’-shaped grooves of the track rollers  4906 , which in turn help keep the torsion plate  4902  between the track rollers  4906 . 
     The slide and pivot assembly may include a center bar  4919  disposed between the track rollers  4906 , which are attached to the bottom one of the mounting brackets  4910 . The center bar  4919  may direct the torsion plate  4902  to slide onto the back track roller (designated  4921 ). The slide and pivot assembly includes a stopper  4920  that is attached to the back end of the torsion plate  4902 . When the torsion plate  4902  is slid out to a fully out position, the stopper  4920  comes in contact with the upper one of the brackets  4910 , which limits and prevents the torsion plate  4902  from being slid out any further. 
       FIG.  51    show a slide and pivot assembly  5100  illustrating directions of torsional and vertical stiffness of a torsion plate  5102 . A bias assembly  5104  is attached to the slide and pivot assembly  5100 , which in turn is attached to a processing chamber  5106 . During sliding movement of the torsion plate  5102 , the torsion plate  5102  may experience torsional and vertical forces due primarily to weight and movement of the bias assembly  5104  relative to the processing chamber  5106 . The torsion plate  5102  provides both torsional and vertical stiffness to support the offset weight of the bias assembly  5104 . 
       FIG.  52    shows a portion  5200  of the slide and pivot assembly of  FIG.  51    illustrating horizontal and vertical space constraints. The horizontal space constraint may refer to a distance from an outer side surface  5202  of the processing chamber  5106  to an outer side surface  5204  of the torsion plate  5102 . The outer side surface  5204  of the torsion plate  5102  may be at least a predetermined distance from another processing chamber disposed adjacent to the processing chamber  5106 . The vertical space constraint may refer to (i) a lowermost point (or height) to which the torsion plate may extend, and (ii) an uppermost point (or height) to which the torsion plate may extend. 
     In  FIG.  52   , bearing blocks  5210  are shown disposed in recessed areas of a sidewall  5212 . The bearing blocks  5210  include the hidden portions  5213  and the non-hidden portions  5214 . The portions  5213  are hidden in  FIG.  52    because these portions are in recessed areas  5211  of the sidewall  5212 , which do not fully extend across the sidewall  5212 . From the opposite (or front) end of the sidewall  5212 , the recessed areas  5211  that include the hidden portions  5213  are visible. Other recessed areas  5215  are shown and extend from a back edge  5217  of the sidewall  5212  to the recessed areas  5211  in which the bearing blocks  5210  are located. The bearing blocks  5210  are attached to the sidewall  5212  . The bearing blocks  5210  may be similar to and operate similarly as the bearing blocks shown in  FIGS.  59 - 60   . Rails  5216  are attached to recessed areas of an inner surface  5222  of the torsion plate  5102 . The rails  5216  engage with and slide in a portion of the bearing blocks  5210  allowing the torsion plate  5102  to be slide relative to the sidewall  5212  between fully retracted and fully pulled-out states. The engagement of the rails  5216  with the bearing blocks  5210  prevents the rails from be pulled away from the bearing blocks  5210  in a direction perpendicular to a slide direction of the rails  5216  by, for example, the torsion plate  5102 . 
       FIG.  53    shows a processing chamber  5300  including another slide and pivot assembly  5302  with cylindrical-shaped rails  5304  and corresponding rail guides  5306 . The rail guides  5306  are attached to a sidewall  5308  of the processing chamber  5300 . The rails  5304  slide in the rail guides  5306  and are attached at front ends to a hinge assembly  5310 , which in turn is attached to a bias plate  5312 . Font ends of the rails  5304  may be slid into cylindrically-shaped slots  5311  in a slide rail member  5312  of the hinge assembly  5310 . The front ends of the rails  5304  may be fastened and/or otherwise connected to the slide rail member  5312 . The rail guides  5306  may include bushings and/or bearings for sliding the rails  5304 . The size of the rails  5304  and rail guides  5306  are selected to minimize and/or prevent rail twist. For increased rigidity, the rails  5304  and the rail guides  5306  may be replaced with web rails  5400  and corresponding rail guides  5402 , which are shown in  FIG.  54   . 
       FIG.  54    show a portion  5406  of another slide and pivot assembly including the web rails  5400  and corresponding rail guides  5402 . The web rails  5400  may be attached to a hinge assembly (a portion  5410  of which is shown in  FIG.  54   ). The rail guides  5402  are blocks that may be attached to a sidewall of a processing chamber via fasteners. Each of the web rails  5400  includes cylindrical-shaped longitudinal edges  5422 ,  5424  with a longitudinal member  5426  extending therebetween. The rail guides  5402  may include bushings and/or bearings for sliding the rails  5400 . 
       FIGS.  55 - 56    show a portion  5500  of another slide and pivot assembly including a torsion plate  5502  with top and bottom edge roller guides  5504  and corresponding roller blocks  5506 . The roller blocks  5506  may be attached to a sidewall of a processing chamber. Each of the roller guides  5504  includes a recessed ‘V’-shaped track  5510  along which cross-connected rollers  5512 ,  5514  roll. The rollers  5512 ,  5514  may include bearings and fasteners for attaching to the roller guides  5504 . The first rollers  5512  roll on a first side surface  5516  of the track  5510  and the second rollers  5514  roll on a second side surface  5518  of the track  5510 . The second rollers  5514  and/or corresponding fasteners may be arranged perpendicular relative to the first rollers  5512  and/or corresponding fasteners. The cross-connected rollers  5512 ,  5514  maintain the torsion plate  5502  is a same lateral position relative to the sidewall of the processing chamber. The torsion plate  5502  may be moved relative to the roller blocks  5506  between fully extended and fully retracted positions in a similar manner as the other torsion plates referred to herein. 
       FIG.  57    shows the edge roller guide  5504  and the roller block  5506  including one of the rollers  5512 . The edge roller guide  5504  is attached to a top or bottom edge of the torsion plate  5502 . As an alternative, the edge roller guide  5504  may be integrally formed as part of the torsion plate  5502 .  FIG.  58    shows an example of this including a torsion plate  5800  with an integrally formed edge roller guide portion  5802  with a track  5804  for a roller  5512 . The roller  5512  is attached to the roller block  5506 . 
       FIGS.  59 - 60    show a processing chamber  5900  including another slide and pivot assembly  5902  including a ‘C’-shaped torsion plate  5904  with an end cap  5906  and support rails  5908  sliding relative to open bearing blocks  5910 . The bearing blocks  5910  are attached to a sidewall  5912  of a processing chamber  5900 . The bearing blocks  5910  include open bearings for sliding the support rails  5908  relative to the sidewall  5912 . The torsion plate  5904  and the end cap  5906  may be formed of steel. A hinge assembly  5920  may be attached to the end cap  5906  and to a bias plate  5922 . 
     Each of the support rails  5908  includes a flat side  5930  and a curved portion  5932 . The curved opposing sides contact the bearing blocks  5910 . The flat sides  5930  face away from the sidewall  5912  and is visible through rectangular-shaped openings in the corresponding ones of the bearing blocks  5910 . In one embodiment, the bearing blocks  5910  of each of the support rails  5908  are combined to provide single longer bearing blocks than shown in  FIGS.  59 - 60   . For example, in the current example, four bearing blocks are shown (two for each support rail). Two longer bearing blocks may be provided to replace the four bearing blocks. 
       FIG.  61    shows a portion  6100  of another slide and pivot assembly including telescopic rails  6102  and slides  6104 . The telescopic rails  6102  are attached to an inner side  6106  of a torsion plate  6108 . The slides  6104  have a ‘C’-shaped cross-section and slide on the telescopic rails  6102  via bearings  6110 . The bearings  6110  may be (i) disposed between upper and lower sides  6112 ,  6114  of the telescopic rails  6102  and upper and lower inner sides of the slides  6104 , (ii) held in place by the telescopic rails  6102 , and/or (iii) held in place by the slides  6104 . The slides  6104  are attached to a sidewall  6120  of a processing chamber. The telescopic rails  6102  and/or bearings  6110  may be greased (or otherwise lubricated). Sliding the torsion plate  6108  from fully retracted to fully extended states includes sliding the telescopic rails  6102  relative to the slides  6104 . In another embodiment, the telescopic rails are attached to the sidewall  6120  and the slides  6104  are attached to the torsion plate  6108 . A slide lock assembly  6200  may be disposed below the torsion plate  6108  and be attached to the sidewall  6120  and is used to lock and prevent sliding movement of the torsion plate  6108 . The slide lock assembly  6200  is configured similarly to and operates similarly as the slide lock assembly  1101  of  FIG.  12   . 
       FIG.  63    shows a portion  6300  of another slide and pivot assembly including a torsion plate  6302  with top and bottom edge rails (the top one of which is designated  6304 ) for roller assemblies  6308 ,  6310  with ‘V’-shaped grooved track rollers  6312 ,  6314 . The edge rails ride on ‘V’-shaped grooves of the track rollers  6312 ,  6314 . The ‘V’-shaped grooves aid in maintaining lateral position of the torsion plate  6302  relative to a sidewall of a processing chamber. 
     The roller assemblies  6308 ,  6310  may be attached to the sidewall of the processing chamber via (i) fasteners  6320 ,  6322 , which extend through housings  6322 ,  6324  of the slide assemblies  6308 ,  6310  and the track rollers  6312 ,  6314  and screw into the sidewall; and/or (ii) other fasteners (not shown) extending through the housings  6322 ,  6324  and a center block  6330  and a slide lock assembly  6332 . The center block  6330  is disposed between the track rollers  6312  and may include a ‘V’-shaped groove  6331  through which the top edge rail  6304  slides. The slide lock assembly  6332  is disposed between the track rollers  6314  and is used to lock and prevent sliding movement of the torsion plate  6302 . The slide lock assembly  6332  is configured similarly to and operates similarly as the slide lock assembly  1101  of  FIG.  12   . A block  6334  of the slide lock assembly  6332  may include a ‘V’-shaped groove similar as the ‘V’-shaped groove of the center block  6330  for the bottom edge rail. The blocks  6330  and  6334  function as redundant supports to retain the torsion plate  6302  in the event of V-wheel bearing failure. 
       FIGS.  26 ,  59  and  63    show hinge assemblies having a “lift-off” design for lifting off a bias plate and corresponding bias mounting plate member of the hinge assembly from a slide torsion plate member of the hinge assembly. Referring to  FIG.  63   , which shows a hinge assembly  6340  including a slide torsion plate member  6342  attached to the torsion plate  6302  and a bias mounting plate member  6344 . The members  6342 ,  6344  are each ‘U’-shaped, where fingers  6346  of the bias mounting plate member  6344  sit on respective fingers  6348  of the slide torsion plate member  6342 . In the example shown, a shaft  6350  extends through the fingers  6346 ,  6348  and is held in place relative to the members  6342 ,  6344  by nuts  6352 ,  6354  that are on threaded ends of the shaft  6350 . The shaft  6350  passes through a circular member  6351  of a pivot block (similar to pivot block  1704  of  FIG.  17   ) that is fastened via a plate  6353  to the slide torsion plate member  6342  between one of the fingers  6348  and one of the fingers  6346 . The circular member  6351  is attached to the plate  6353 . A pivot lock assembly  6355  engages with the circular holding member  6351 , similarly as the pivot lock assembly  814  of  FIG.  17   . The shaft  6350  extends through the circular member  6351 . A corresponding bias plate (not shown in  FIG.  63   ) that is attached to the bias mounting plate member  6344  is able to be removed along with the bias mounting plate member  6344  from the slide torsion plate member  6342  by simply removing the nuts  6352 ,  6354  and the shaft  6350 . Although the shaft  6350  is shown, the shaft may be replaced with upper and lower pins similar to the pin  2502  shown in  FIGS.  24 - 25   . 
     Although certain fasteners are referred to above, various additional fasteners (e.g., screws, nuts, pins, bolts, etc.) may be included in the above examples, some of which are shown in the figures.
