     DETAILED DESCRIPTION 
     The following disclosure provides many different embodiments, or examples, for implementing different features of the provided subject matter. Specific examples of components and arrangements are described below to simplify the present disclosure. These are, of course, merely examples and are not intended to be limiting. For example, the formation of a first feature over or on a second feature in the description that follows may include embodiments in which the first and second features are formed in direct contact, and may also include embodiments in which additional features may be formed between the first and second features, such that the first and second features may not be in direct contact. In addition, the present disclosure may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. 
     Further, spatially relative terms, such as “beneath,” “below,” “lower,” “above,” “upper” and the like, may be used herein for ease of description to describe one element or feature&#39;s relationship to another element(s) or feature(s) as illustrated in the figures. The spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. The apparatus may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein may likewise be interpreted accordingly. 
     A plurality of semiconductor wafers and/or other types of substrates may be transported throughout a semiconductor fabrication facility in a transport carrier. A transport carrier may include a wafer cassette, a front-opening unified pod (FOUP), a pod, a container, or a similar type of device. To transfer a semiconductor wafer from a transport carrier to a semiconductor processing tool, the transport carrier may be placed in and/or on a load port associated with the semiconductor processing tool. A transport tool included in an interface tool (e.g., an equipment front end module (EFEM) or similar type of interface tool) that is situated between the semiconductor processing tool and the load port may remove the semiconductor wafer from the transport carrier. The transport tool may transfer the semiconductor wafer from the transport carrier to the semiconductor processing tool through a chamber of the interface tool. The transport tool may perform the above-described process in reverse to transfer the semiconductor wafer from the semiconductor processing tool to the transport carrier after processing. 
     Semiconductor wafers may be exposed to contaminants (e.g., volatile organic compounds (VOCs), dust, debris, and other types of contaminants) in the semiconductor fabrication facility during transfer of the semiconductor wafers between a load port and an associated semiconductor processing tool. These contaminants may cause semiconductor device failures, may cause defects to occur in the integrated circuits and/or semiconductor devices formed in the semiconductor fabrication facility, and may reduce manufacturing yield and quality, among other examples. Moreover, the impact of the contaminants in the semiconductor fabrication facility may continue to become more significant due to decreased tolerance to the contaminants as device and/or feature sizes of the integrated circuits and/or semiconductor devices, that are to be formed on semiconductor wafers in the semiconductor fabrication facility, continue to shrink. 
     Some implementations described herein provide a multiple transport carrier docking device that can be positioned between a load port and an interface tool to reduce and/or minimize cross contamination of semiconductor wafers that are transferred between the load port and an associated semiconductor processing tool. The multiple transport carrier docking device may be capable of forming an air-tight seal around a transport carrier while the transport carrier is in a chamber of the multiple transport carrier docking device. In this way, semiconductor wafers in the transport carrier may be accessed by a transport tool while the air-tight seal around the transport carrier prevents and/or reduces the likelihood that contaminants in the semiconductor fabrication facility will reach the semiconductor wafers. Accordingly, the air-tight seal around the transport carrier may reduce defects of the semiconductor wafers that might otherwise be caused by the contaminants, may increase manufacturing yield and quality in the semiconductor fabrication facility, and/or may permit the continued reduction in device and/or feature sizes of integrated circuits and/or semiconductor devices that are to be formed on semiconductor wafers. 
     Moreover, the multiple transport carrier docking device is capable of storing and/or staging a plurality of transport carriers in the chamber at the same time. This may permit transport carriers to be cycled through more quickly as the associated semiconductor processing tool processes the semiconductor wafers included in the plurality of transport carriers, which may increase the capacity and throughput of the associated semiconductor processing tool. 
       FIG.  1    is a diagram of an example semiconductor processing environment  100  described herein. The example semiconductor processing environment  100  may include, or may be included in, a semiconductor fabrication facility, a semiconductor foundry, a semiconductor processing facility, a semiconductor clean room, and/or another environment in which semiconductor wafers and/or devices are processed. As shown in  FIG.  1   , the example semiconductor processing environment  100  may include a semiconductor processing tool  102 , a load port  104 , an interface tool  106 , and a docking device  108 , among other tools and/or devices. 
     The semiconductor processing tool  102  may include one or more tools configured to perform one or more semiconductor processing operations on one or more semiconductor wafers and/or devices. For example, the semiconductor processing tool  102  may include a deposition tool (e.g., a semiconductor processing tool configured to deposit one or more layers onto a semiconductor wafer), a plating tool (e.g., an electroplating tool configured to deposit one or more metal layers onto a semiconductor wafer), an exposure tool (e.g., an extreme ultraviolet (EUV) tool, an electron beam (e-beam) tool), an etch tool (e.g., a wet etch tool, a dry etch tool), or another type of semiconductor processing tool. 
     The load port  104  may include a shuttle platform  110  configured to receive and support a transport carrier  112 . The load port  104  and the shuttle platform  110  may receive the transport carrier  112  from a transport robot, a transport cart, an overhead hoist transport (OHT), or another device configured to move transport carriers to and from various locations in the example semiconductor processing environment  100 . 
     The transport carrier  112  may include a wafer cassette, a FOUP, a pod, a container, or a similar type of device configured to hold and/or store a plurality of semiconductor wafers. The transport carrier  112  may include a body  114  configured to rest on the shuttle platform  110 . The body  114  may be further configured to store a plurality of semiconductor wafers, semiconductor devices, and/or substrates that are to be used in semiconductor processing. The transport carrier  112  may further include a carrier door  116 . The carrier door  116  may be attached to the body  114  and may form an air-tight seal (e.g., a hermetic seal) between the carrier door  116  and the body  114  to reduce, minimize, and/or prevent contamination of the semiconductor wafers stored in the body  114 . 
     The interface tool  106  may include an EFEM or another tool that includes a chamber  118 . Air may be provided to the chamber  118  through a filter  120  (e.g., a high-efficiency particulate air (HEPA) filter or another type of air filter) configured to filter or remove particles and other contaminants from the incoming air. The chamber  118  may further be vented through an exhaust  122 . 
     The interface tool  106  may further include a wafer transport tool  124  in the chamber  118 . The wafer transport tool  124  may include a robotic arm or another type of tool that is configured to transport semiconductor wafers between a transport carrier  112  and the semiconductor processing tool  102 . The wafer transport tool  124  may receive and/or obtain a semiconductor wafer from a transport carrier  112  through an opening  126  between the docking device  108  and the interface tool  106 , and may provide the semiconductor wafer to the semiconductor processing tool  102  through an opening  128  between the interface tool  106  and the semiconductor processing tool  102 . Moreover, the wafer transport tool  124  may receive and/or obtain a semiconductor wafer from a semiconductor processing tool  102  through the opening  128 , and may provide the semiconductor wafer to a transport carrier  112  through the opening  126 . In some implementations, the wafer transport tool  124  transfers semiconductor wafers between a transport carrier  112  and a staging area of the semiconductor processing tool  102 . In some implementations, the wafer transport tool  124  transfers semiconductor wafers between a transport carrier  112  and a processing chamber of the semiconductor processing tool  102 . 
     The docking device  108  is a device that is configured to permit the transfer of semiconductor wafers between a transport carrier  112  and the semiconductor processing tool  102  in a manner that reduces the likelihood of exposure of semiconductor wafers to contaminants that may be present in the example semiconductor processing environment  100 . The docking device  108  may be referred to as a multiple transport carrier docking device in that the docking device  108  is configured to (and/or capable of) storing and/or staging a plurality of transport carriers  112  in a first chamber  130 , as shown in  FIG.  1   . The wafer transport tool  124  may access a transport carrier  112  (e.g., the body  114  of the transport carrier  112 ) through the opening  126  and through a second chamber  132  of the docking device  108 . 
     The first chamber  130  and the second chamber  132  may be separated by a divider wall  134 . The divider wall  134  may include a rigid or semi-rigid structure that extends from the top of the first chamber  130  and the second chamber  132 , to the bottom of the first chamber  130  and the second chamber  132 . The divider wall  134  may further extend from one side of the first chamber  130  and the second chamber  132  to another (opposing) side of the first chamber  130  and the second chamber  132 . 
     An opening  136  may be provided through the divider wall  134 , which may be sealed by a chamber door  138 . In particular, the chamber door  138  may be pressed against the divider wall  134  to form an air-tight seal (e.g., a hermetic seal) between the divider wall  134  and the chamber door  138 . The air-tight seal between the divider wall  134  and the chamber door  138  functions as an air-tight seal between the first chamber  130  and the second chamber  132 . The divider wall  134  and the chamber door  138  may form the air-tight seal when the chamber door  138  is in a closed position, as shown in  FIG.  1   . The air-tight seal may reduce, minimize, and/or eliminate the likelihood that contaminants in the example semiconductor processing environment  100  might otherwise travel from the first chamber  130  to the second chamber  132  through the opening  136  in the divider wall  134 . 
     In some implementations, the divider wall  134  and/or the chamber door  138  may include a gasket, a strip, or another component to form the air-tight seal. The gasket of the divider wall  134 , if included, may be formed around the opening  136  in the divider wall  134 . The gasket of the chamber door  138 , if included, may be formed in a shape that substantially fits around the opening  136  in the divider wall  134 . The gasket of the divider wall  134  and/or the gasket of the chamber door  138  may be formed of a soft material and/or of a deformable material to permit the air-tight seal to be formed. For example, the gasket of the divider wall  134  and/or the gasket of the chamber door  138  may be formed of a plastic material, a rubber material, a silicone material, or a similar material. In some implementations, the material of the gasket of the divider wall  134  and/or the gasket of the chamber door  138  includes a gas impermeable material. 
     The first chamber  130  of docking device  108  may include a door  140  that seals around an opening at a first side (e.g., a first side wall) of the docking device  108 . In some implementations, the door  140  (and the associated opening) is on an opposing side of the docking device  108  to the opening  126 , which may be at a second side (e.g., a second side wall) of the docking device  108 . In some implementations, the door  140  (and the associated opening) and the opening  126  are on adjacent sides (e.g., adjacent side walls) of the docking device  108 . 
     The door  140  (and the associated opening) may be orientated toward the load port  104  to permit transport carriers  112  to be transferred between the shuttle platform  110  and the first chamber  130 . The door  140  may be opened (e.g., removed from the opening) to provide access to the first chamber  130  for insertion of a transport carrier  112  into the first chamber  130 , and for removal of a transport carrier  112  from the first chamber  130 . The opening  126  may provide access to the second chamber  132  for the wafer transport tool  124 . 
     Air may be provided to the first chamber  130  through a filter  142  (e.g., a HEPA filter or another type of air filter) configured to filter or remove particles and other contaminants from the incoming air flowing into the first chamber  130 . The first chamber  130  may further be vented through an exhaust  144 . 
     As indicated above, the docking device  108  may be configured to store and/or stage a plurality of transport carriers  112  in the first chamber  130 . The first chamber  130  may include a plurality of moveable platforms  146  on which transport carriers  112  may be placed and/or supported. Each moveable platform  146  may be configured support a respective transport carrier  112 . Each movable platform  146  may be sized to a greater size relative to the transport carriers  112  (e.g., a greater length and/or a greater width) to reduce, minimize, and/or prevent vibration of the transport carriers. The movable platforms  146  may be configured to slide and/or otherwise move in one or more directions within the first chamber  130  to permit access to each moveable platform  146  through the opening that is orientated toward the load port  104 . For example, the moveable platforms  146  may be configured to slide and/or otherwise move in a vertical direction (e.g., up and down) in the first chamber  130 . As another example, the moveable platforms  146  may be configured to slide and/or otherwise move in a horizontal direction (e.g., side to side) in the first chamber  130 . As another example, the moveable platforms  146  may be configured to slide and/or otherwise move in a vertical direction (e.g., up and down) and in a horizontal direction (e.g., side to side) in the first chamber  130 . In these examples, all of the moveable platforms  146  may move together at the same time, or individual moveable platforms  146  may move independently of the other moveable platforms  146 . 
     The docking device  108  may include a plurality of shuttle trays  148 . Each moveable platform  146  may include a respective shuttle tray  148  and one or more latches  150 . Each shuttle tray  148  may be configured to receive and support a respective transport carrier  112 . Moreover, each shuttle tray  148  may slide or otherwise move in one or more directions to move a transport carrier  112  toward and away from a sealing component  152  in the first chamber  130 . For example, a shuttle tray  148  may slide and/or otherwise move relative to an associated moveable platform  146  to extend toward the sealing component  152 , and may slide and/or otherwise move relative to the associated moveable platform  146  to retract away from the sealing component  152 . 
     The one or more latches  150  included in a moveable platform  146  may be attached, connected, and/or otherwise supported by the moveable platform  146 . The one or more latches  150  may be configured to extend away from the moveable platform  146  and toward a moveable frame  154  to which the sealing component  152  is attached, mounted, and/or otherwise supported. Moreover, the one or more latches  150  may be configured to retract toward the moveable platform  146  and away from the moveable frame  154 . The one or more latches  150  may connect to the moveable platform  146  when the one or more latches  150  are extended. This permits movement of the moveable platform  146  to cause the moveable frame  154  to move along with the moveable platform  146 . In this way, the moveable frame  154  may be an unpowered moveable frame (e.g., a moveable frame without a dedicated motor and/or drive mechanism to move the moveable frame), which reduces the complexity of the moveable frame  154 . Moreover, the one or more latches  150  permit the movement of the moveable platform  146  and the movement of the moveable frame  154  to be synchronized. 
     The sealing component  152  included in the first chamber  130  of the docking device  108  may be configured to reduce, minimize, and/or eliminate the likelihood of exposure to contaminants that may be present in the example semiconductor processing environment  100  when a semiconductor wafer is transferred between the transport carrier  112  and the semiconductor processing tool  102 . The sealing component  152  may be pressed against the moveable frame  154  on a side (or face) of the moveable frame  154  facing the first chamber  130 . One or more gaskets may be located between the sealing component  152  and moveable frame  154  to reduce, minimize, and/or prevent air (and contaminants carried by the air) from passing between the sealing component  152  and the moveable frame  154 . 
     The sealing component  152  may include one or more portions that are configured to form an air-tight seal (e.g., a hermetic seal) around a transport carrier  112  when a transport carrier  112  is extended toward the sealing component  152  on a shuttle tray  148 . For example, the shuttle tray  148  may slide or otherwise move the transport carrier  112  toward the sealing component  152  in the first chamber  130 . With the transport carrier  112  extended toward the sealing component  152 , the sealing component  152  may contract around the transport carrier  112  (e.g., around the body  114  of the transport carrier  112 ) to form the air-tight seal between the sealing component  152  and the transport carrier  112 . 
     The one or more portions of the sealing component  152  may be positioned around an opening in the moveable frame  154 . The carrier door  116  of the transport carrier  112  may extend into and/or through the opening in the moveable frame  154  when the transport carrier  112  extended toward the sealing component  152 . This permits the one or more portions of the sealing component  152  to contract around the body  114  of the transport carrier  112  (e.g., to form the air-tight seal around the body  114  of the transport carrier  112 ) as opposed to the carrier door  116  of the transport carrier  112 , which permits the carrier door  116  to be removed from the body  114  of the transport carrier  112 . 
     In some implementations, the sealing component  152  (or the portions thereof) are formed of a relatively soft material (e.g., softer than the material of the body  114  of the transport carrier  112 ) to permit the air-tight seal to be formed around the transport carrier  112 . For example, the sealing component  152  (or the portions thereof) may be formed of a plastic material, a rubber material, a silicone material, a gas impermeable, or a similar material. In some implementations, the sealing component  152  (or the portions thereof) includes a gasket, a strip, or a similar component formed of a relatively soft material that is pressed against the body  114  of the transport carrier  112  to form the air-tight seal. 
     When the air-tight seal is formed between the sealing component  152  and a transport carrier  112 , the chamber door  138  may remove the carrier door  116  from the body  114  of the transport carrier  112 . After removing the carrier door  116 , the chamber door  138  may transition from the closed position shown in  FIG.  1    to an open position, which releases the air-tight seal between divider wall  134  and the chamber door  138 . Here, the chamber door  138  (with the removed carrier door  116 ) may move backwards away from the divider wall  134  toward the opening  126 , and may move downward into the second chamber  132  (e.g., after moving backwards away from the divider wall  134 ). In this way, the opening  136  in the divider wall  134  is cleared such that the wafer transport tool  124  is permitted to access the transport carrier  112  (e.g., the body  114  of the transport carrier  112 ) through the opening  136  in the divider wall  134  and the opening  126  while the air-tight seal is formed around the transport carrier  112  by the sealing component  152 . 
     Prior to removing the carrier door  116  from the body  114  of the transport carrier  112 , the moveable platform  146  on which the transport carrier  112  may move to adjust the position of the transport carrier  112 . In this way, the moveable platform  146  may move to align the carrier door  116 , the opening in the moveable frame  154 , and the opening  136  in the divider wall  134  so that the carrier door  116  is accessible by the chamber door  138 , and so that the carrier door  116  may pass through the opening in the moveable frame  154  and the opening  136  in the divider wall  134 . 
     The moveable frame  154  may be permitted to slide and/or otherwise move along a set of tracks  156 . The track(s)  156  may be mounted, connected, attached, and/or supported by the divider wall  134 . The track(s)  156  may include one or more tracks, one or more rails, one or more tubes, roller bearings, or there types of structures that permit the moveable frame  154  to slide and/or otherwise move based on movement of a moveable platform  146 . The track(s)  156  may include one or more elongated members that extend parallel to the direction of travel of the moveable frame  154 . The length of the elongated members may be greater than the length of the moveable frame  154  to permit the moveable frame to move along the track(s)  156 . 
     In some implementations, the docking device  108  includes one or more sensors (e.g., proximity sensors, hall effect sensors, or other types of sensors) configured to detect and/or indicate whether the carrier door  116 , the opening in the moveable frame  154 , and the opening  136  are aligned. In some implementations, the one or more sensors cause an indication (e.g., a visual indication, an audible indication, or another type of indication) to be presented to an operator if the moveable platform  146  is manually operated by the operator. In some implementations, the one or more sensors automatically cause the movement of the moveable platform  146  to stop based on detecting or determining that alignment between the carrier door  116 , the opening in the moveable frame  154 , and the opening  136 . In some implementations, the one or more sensors automatically provide a signal, a message, or another type of indicator to a processor or controller of the docking device  108  based on detecting or determining that alignment between the carrier door  116 , the opening in the moveable frame  154 , and the opening  136 , and the processor or controller automatically causes the movement of the moveable platform  146  to stop based on the indicator. 
     The wafer transport tool  124  may transfer semiconductor wafers between the transport carrier  112  and the semiconductor processing tool  102  after the air-tight seal is formed around the transport carrier  112  by the sealing component  152 , and after the chamber door  138  is opened. For example, the wafer transport tool  124  may obtain and/or retrieve a semiconductor wafer from the transport carrier  112  through the opening  136  in the divider wall  134  and through the opening  126 , and may provide the semiconductor wafer to the semiconductor processing tool  102  through the opening  128 . As another example, the wafer transport tool  124  may obtain a semiconductor wafer from the semiconductor processing tool  102  through the opening  128 , and may provide the semiconductor wafer to the transport carrier  112  through the opening  126  and the opening  136  in the divider wall  134 . 
     In this way, with the carrier door  116  removed and the chamber door  138  in the open position, air-tight seals are formed between the body  114  of the transport carrier  112  and the side wall on which the opening  126  is located. In particular, an air-tight seal may be formed between the body  114  of the transport carrier  112  and the sealing component  152 , an air-tight seal may be formed between the sealing component  152  and the moveable frame  154 , an air-tight seal may be formed between the moveable frame and a side of the divider wall  134 , an air-tight seal may be formed between the divider wall  134  and the top, bottom, and sides of the first chamber  130  and the second chamber  132 . This provides an air-tight seal from the transport carrier  112  through the second chamber  132  and to the opening  128 . The air-tight seal from the transport carrier  112  through the second chamber  132  and to the opening  128  permits the transport carrier  112  to be accessed without exposing the semiconductor wafers that are between the transport carrier  112  and the semiconductor processing tool  102  to contaminants in the example semiconductor processing environment  100 . 
     As indicated above,  FIG.  1    is provided as an example. Other examples may differ from what is described with regard to  FIG.  1   . 
       FIGS.  2 A- 2 F  are diagrams of example implementations of the sealing component  152  for forming an air-tight seal around a transport carrier  112  described herein.  FIG.  2 A  illustrates perspective views of example implementations  210  and  220  of the sealing component  152  in which the sealing component  152  includes four portions: a portion  152   a , a portion  152   b , a portion  152   c , and a portion  152   d . Example implementation  210  illustrates an example of the sealing component  152  in an expanded configuration, where the portion  152   a , the portion  152   b , the portion  152   c , and the portion  152   d  are not contracted around the body  114  of the transport carrier  112 . In this configuration, the portion  152   a , the portion  152   b , the portion  152   c , and the portion  152   d  may spaced away from the body  114  of the transport carrier  112  at a distance that permits the door  140  and the body  114  of the transport carrier  112  to fit through an opening  212  formed by the portion  152   a , the portion  152   b , the portion  152   c , and the portion  152   d . The opening  212  may be referred to as an airflow/vacuum hole. 
     As further shown in the example implementation  220  in  FIG.  2 A , the sealing component  152  may transition to a contracted configuration, in which the portion  152   a , the portion  152   b , the portion  152   c , and the portion  152   d  are contracted around the body  114  of the transport carrier  112  to form the air-tight seal around the transport carrier  112 . 
       FIG.  2 B  illustrates an elevation view of an example implementation  230 , which shows a first position  240  of the portion  152   a , the portion  152   b , the portion  152   c , and the portion  152   d , and a second position  250  of the portion  152   a , the portion  152   b , the portion  152   c , and the portion  152   d . The first position  240  may correspond to the expanded configuration illustrated in the example implementation  210  of  FIG.  2 A , and the second position  250  may correspond to the contracted configuration illustrated in the example implementation  220  of  FIG.  2 A .

In some implementations, one or more of the portion  152   a , the portion  152   b , the portion  152   c , or the portion  152   d  transition between the first position  240  and the second position  250  in a non-linear path of travel. In some implementations, one or more of the portion  152   a , the portion  152   b , the portion  152   c , or the portion  152   d  transition between the first position  240  and the second position  250  in a non-linear path of travel.

     As indicated above,  FIGS.  2 A- 2 F  are provided as examples. Other examples may differ from what is described with regard to  FIGS.  2 A- 2 F . In some implementations, the sealing component  152  may include five or more portions in various configurations different from those described herein. 
       FIG.  3    is a diagram of portion  300  of the example semiconductor processing environment  100  of  FIG.  1   , described herein. As shown in  FIG.  3   , the portion  300  may include the divider wall  134 , the chamber door  138 , a moveable platform  146 , a shuttle tray  148 , one or more latches  150 , the sealing component  152 , the moveable frame  154 , and the track(s)  156 . 
     The divider wall  134  may include an elongated body in which the opening  136  is included. The track(s)  156  may be attached, connected, and/or otherwise mounted to a side of the elongated body of the divider wall  134 . The moveable frame  154  may be mounted to and/or interfaced with the track(s)  156 . The moveable frame  154  may include a substantially planar body that permits the moveable frame  154  to move along the track(s)  156  substantially parallel to the elongated body of the divider wall  134 . 
     The sealing component  152  may include a plurality of portions, such as portion  152   a , portion  152   b , portion  152   c , and portion  152   d . The sealing component  152  (or the portions thereof) may be attached, connected, and/or otherwise mounted to a side of the elongated body of the moveable frame  154 , such as the side of the elongated body of the moveable frame  154  opposing the side of the elongated body of the moveable frame  154  that is orientated and/or facing toward the divider wall  134 . The sealing component  152  may be attached, connected, and/or otherwise mounted to the moveable frame  154  in a manner that permits the portions of the sealing component  152  to expand and contract between a first position  240  and a second position  250  to form or release an air-seal around a transport carrier  112 . 
     The body  114  of the transport carrier  112  may be positioned on the shuttle tray  148  above the moveable platform  146 . The one or more latches  150  of the moveable platform  146  may extend away from the moveable platform  146  and toward the moveable frame  154 . The one or more latches  150  include one or more tabs, hooks, pins, or other structures that connect with one or more connectors  302  included on the moveable frame  154 . With the one or more latches  150  connected with the one or more connectors  302 , movement of the moveable platform  146  may cause the moveable frame  154  to move along the track(s)  156 . 
     As further shown in  FIG.  3   , the portion  300  may include the chamber door  138 . The chamber door  138  may include an elongated body that is substantially parallel to the elongated body of the divider wall  134 . Moreover, the chamber door  138  may include a mounting plate  304  attached, connected, and/or otherwise mounted to a support structure  306 . The support structure  306  may be attached, connected, and/or otherwise mounted to the elongated body of the chamber door  138 . The mounting plate  304  and the support structure  306  may be attached, connected, and/or otherwise mounted to a side of the elongated body of the chamber door  138  that faces the divider wall  134 . In this way, the mounting plate  304  faces the opening  136  in the divider wall  134 . In particular, the mounting plate and the support structure  306  may be mounted to the side of the chamber door  138  that faces the side of the divider wall  134  that opposes the side of the divider wall  134  on which the track(s)  156 , the moveable frame  154 , and the sealing component  152  are mounted. 
     The mounting plate  304  may be configured to remove a carrier door  116  from the body  114  of the transport carrier  112 . The mounting plate  304  may be configured to hold and/or support the carrier door  116  when the chamber door  138  moves between the closed position and the open position. The mounting plate  304  may be configured to place the carrier door  116  onto the body  114  of the transport carrier  112 . The mounting plate  304  may include one or more vacuum holes  308  and one or more latch keys  310 . The vacuum holes  308  may be connected to tube(s), plumbing fixture(s), and/or one or more other components that are configured to pull air through the vacuum holes  308  to form a negative pressure on the face of the mounting plate  304  near the vacuum holes  308 . The negative pressure may form a suction or a vacuum seal between the mounting plate  304  and the carrier door  116 . The mounting plate  304  may hold and/or support the carrier door  116  based on the negative pressure generated through the vacuum holes  308 . 
     The latch key(s)  310  may be configured to unlatch the carrier door  116  from the body  114  of the transport carrier  112 . For example, the latch key(s)  310  may include a key, an elongated member, or another component that is configured to open a door latch and/or a door lock on the carrier door  116 . In some implementations, the mounting plate  304  includes a single latch key  310  (e.g., on a side of the mounting plate  304  or substantially near a center of the mounting plate  304 ). In some implementations, the mounting plate  304  includes a plurality of latch keys  310  substantially near one or more edges of the mounting plate  304 . 
     The support structure  306  may include a jack (e.g., a scissor jack, a hydraulic jack, a pneumatic jack, or another type of jack), a screw mechanism, a rail system, or another type of structure configured to extend the mounting plate  304  away from the elongated body of the chamber door  138  and contract the mounting plate  304  toward the elongated body of the chamber door  138 . In this way, the support structure  306  may extend the mounting plate  304  toward and/or through the opening  136  in the divider wall  134  to remove the carrier door  116  from the transport carrier  112 , may contract the mounting plate  304  after removing the carrier door  116  so that the chamber door  138  may be moved to the opened position, and may extend the mounting plate  304  toward transport carrier  112  to place the carrier door  116  onto the transport carrier  112 . 
     As indicated above,  FIG.  3    is provided as an example. Other examples may differ from what is described with regard to  FIG.  3   . 
       FIGS.  4 A- 4 K  are diagrams of one or more example implementations  400  described herein. The example implementation(s)  400  may include one or more example implementations illustrating various operations of the docking device  108  and other tools included in the example semiconductor processing environment  100 . As shown in  FIG.  4 A , a transport carrier  112  may be placed on the shuttle platform  110  of the load port  104 . For example, a mobile robot, an OHT, or another transport tool may place the transport carrier  112  on the shuttle platform  110 . 
     As shown in  FIG.  4 B , the door  140  on the side of the first chamber  130  may be opened to provide access to the docking device  108  through an opening  402  in the first chamber  130 . As further shown in  FIG.  4 B , the moveable platforms  146  may move (e.g., downward in the first chamber  130 ) to align an empty moveable platform  146  with the opening  402  in preparation for the transport carrier  112  on the shuttle platform  110  to be placed on the empty moveable platform  146 . 
     As shown in  FIG.  4 C , the shuttle platform  110  may slide or otherwise move toward the opening  402  in the first chamber  130  such that the transport carrier  112  is fully inserted into the first chamber  130  through the opening  402  and placed on the empty moveable platform  146 . In particular, the transport carrier  112  may be placed on the shuttle tray  148  of the empty moveable platform  146 . In some implementations, the door  140  may be moved to close the opening  402  after the transport carrier  112  is placed on the empty moveable platform  146 . In some implementations, the door  140  may remain in place such that the opening  402  remains cleared after the transport carrier  112  is placed on the empty moveable platform  146 . 
     As shown in  FIG.  4 D , the moveable platforms  146  may move (e.g., upward in the first chamber  130 ) to align the transport carrier  112  with the sealing component  152  and/or the opening in the moveable frame  154  in preparation for the transport carrier  112  to be accessed by the wafer transport tool  124 . 
     As shown in  FIG.  4 E , with the transport carrier  112  aligned with the sealing component  152  and/or the opening in the moveable frame  154 , the shuttle tray  148  may slide or otherwise extend toward the sealing component  152  such that the carrier door  116  is placed at least partially through the opening in the moveable frame  154 , and such that portions of the sealing component  152  are around the body  114  of the transport carrier  112 . 
     Moreover, the one or more latches  150 , of the moveable platform  146  on which the transport carrier  112  is positioned, may extend away from the moveable platform  146  and toward the moveable frame  154 . The one or more latches  150  may connect with one or more connectors  302  of the moveable frame  154  to permit the movement of the moveable platform  146  to cause the moveable frame  154  to move in synchronization with the moveable platform  146 . 
     With the portions of the sealing component  152  around a portion of the body  114 , the sealing component  152  may contract around the transport carrier  112  to form an air-tight seal around the body  114  of the transport carrier  112 . In particular, the air-tight seal may be formed between the sealing component  152  and the transport carrier  112 . In this way, the area around the transport carrier  112  is sealed to reduce, minimize, and/or eliminate the flow of contaminants from the example semiconductor processing environment  100  through the opening in the moveable frame  154  and the opening  136  in the divider wall  134 , and into the second chamber  132 . The portions of the sealing component  152  may transition from a first position  240  (e.g., corresponding to an expanded configuration) to a second position  250  (e.g., corresponding to a contracted configuration) to form the air-tight seal around the body  114  of the transport carrier  112 . 
     As shown in  FIG.  4 F , with the air-tight seal formed around the transport carrier  112  by the sealing component  152 , the chamber door  138  may remove the carrier door  116  from the transport carrier  112 . For example, the support structure  306  may extend the mounting plate  304  toward the carrier door  116  through the opening  136  in the divider wall  134 . The one or more latch keys  310  on the mounting plate  304  may unlatch the carrier door  116  from the body  114  of the transport carrier  112 . The vacuum holes  308  on the mounting plate  304  may form a vacuum seal between the carrier door  116  and the mounting plate  304 . With the vacuum seal formed, the support structure  306  may contract the mounting plate  304  (with the carrier door  116  supported and/or held thereon) toward the chamber door  138 . 
     As further shown in  FIG.  4 F , the chamber door  138  may slide and/or otherwise move backward away from the divider wall  134  and toward the opening  126 , which removes the air-tight seal between divider wall  134  and the chamber door  138 . In particular, the chamber door  138  may slide and/or otherwise move backward away from the divider wall  134  and toward the opening  126  after removing the carrier door  116  from the transport carrier  112  and contracting the mounting plate  304  toward the chamber door  138 . The chamber door  138  may slide and/or otherwise move backward away from the divider wall  134  a sufficient distance to permit the carrier door  116  to clear the divider wall  134  when the chamber door  138  slides and/or otherwise moves downward into the second chamber  132 . 
     As shown in  FIG.  4 G , the chamber door  138  may slide and/or otherwise move out of the way of the opening  136  in the divider wall  134  such that the wafer transport tool  124  is permitted to access the transport carrier  112  through the opening  136  in the divider wall  134 . In some implementations, the chamber door  138  slides and/or otherwise moves downward within the second chamber  132 . In some implementations, the chamber door  138  slides and/or otherwise moves upward within the second chamber  132 . In some implementations, the chamber door  138  slides and/or otherwise moves to a side within the second chamber  132 . In some implementations, the chamber door  138  slides and/or otherwise moves in a combination of directions within the second chamber  132 . 
     As shown in  FIG.  4 H , the wafer transport tool  124  of the interface tool  106  may retrieve and/or obtain a wafer  404  from the transport carrier  112  through the opening  136  in the divider wall  134  and through the opening  126 . In this way, the wafer transport tool  124  retrieves and/or obtains the wafer  404  from the transport carrier  112  while the air-tight seal is formed around the transport carrier  112  by the sealing component  152 . As shown in  FIG.  4 I , the wafer transport tool  124  may retract the wafer  404  through the opening  136  in the divider wall  134  and through the opening  126  into the chamber  118  of the interface tool  106 . As shown in  FIG.  4 J , the wafer transport tool  124  may provide the wafer  404  to the semiconductor processing tool  102  through the opening  128 . The wafer  404  may be processed by the semiconductor processing tool  102  through one or more semiconductor processing operations. The operations described above may be performed in a reverse order to place the wafer  404  back into the transport carrier  112 . 
     As shown in  FIG.  4 K , the moveable platforms  146  may move in the first chamber  130  while the carrier door  116  of the transport carrier  112  is removed. This may permit other transport carriers  112  to be removed from the first chamber  130  and/or to permit other transport carriers  112  to be added to the first chamber  130  while semiconductor wafers of the transport carrier  112  are being processed by the semiconductor processing tool  102 . This may further increase the efficiency and throughput of the semiconductor processing tool  102  and/or the efficiency and throughput of the docking device  108 , as the docking device  108  may continue to be loaded and unloaded without stopping the productivity of the semiconductor processing tool  102 . 
     As indicated above,  FIGS.  4 A- 4 K  are provided as examples. Other examples may differ from what is described with regard to  FIGS.  4 A- 4 K .
