Title: Process to form gate
Inventor: HSIAO HSI-MAO
IPC: H01L21/28
Filed: 2000-05-03
Granted: 2001-06-23
Abstract: This invention provides a process to form gates on a semiconductor chip, which can avoid circuit short resulting from residual conductive matter on the gate side wall surface. A quasi-gate structure is formed on the substrate surface, which contains, from bottom to top, a gate dielectric layer, a polysilicon layer and a transition layer. The transition layer is removed after a side wall is formed around the quasi-gate structure. Finally, a silicide layer is formed on the polysilicon layer and the silicon substrate around the side wall. The side wall will be protruded out from the both sides of the polysilicon layer, after the removal of the transition layer, to prevent circuit short due to the electric conduction between silicides on the polysilicon layer and silicon substrate caused by the residual conductive matter on the side wall surface.

Title: Image display device to prolong the lifetime of organic electroluminescent device by controlling the transmission
Inventor: KONDO YUJI
IPC: G09G3/32
Filed: 2000-05-31
Granted: 2002-10-21
Abstract: An image display device of the present invention applies (M x N) data voltages sequentially to M-rows of data lines once per N voltages, and applies the scanning voltage to N-columns of scanning lines in synchronization with the data voltage. The scanning voltage turns on the switching device having M-rows and N-columns once per column, therefore, the (M x N) data voltages applied from M-rows of data lines are held by the voltage holding device having M-rows and N-columns. According to the voltage held by them, the driving transistors having M-rows and N-columns apply a fixed driving voltage to the power supply electrode and to the (M x N) organic EL devices. Therefore, (M x N) organic EL devices are actively driven, and dot matrix images with plural gray scales displayed. However, before the scanning voltage is applied to the n-th column, the condition control device stops applying the driving voltage to M organic EL devices in the n-th column immediately. So, when the images with the same luminance are displayed continuously, the organic EL device are stopped to conduct for prolonging the lifetime of the organic EL elements.

As a result, etching can be performed on its smooth surface, allowing easier microfabrication.

Abstract: A buried ridge semiconductor diode laser, preferably based on the GaAs and AlGaAs family of materials. The upper cladding layer is overlaid with an alumimum-free etch stop layer and aluminum-free confinement layer, preferably of GalnP, of opposite conductivity type opposite that of the upper cladding layer.

Title: Atmospheric wafer transfer module with nest for wafer transport robot and method of implementing same
Inventor: KROEKER TONY R
IPC: B65G49/00
Filed: 2000-06-28
Granted: 2002-11-01
Abstract: A load lock wafer transfer face is provided at an acute angle with respect to a footprint dimension line, so the length of the footprint dimension line does not include the entire minimum length of the wafer transfer distance that must separate a robot from the wafer transfer face of a load lock. Two adjacent load locks provided for use with a robot have two load lock wafer transfer faces defining a nest, in that each such face is at an acute angle with respect to the footprint dimension line. A robot is mounted for rotation at a fixed location relative to wafer cassettes and to the nested load lock wafer transfer faces, avoiding use of a robot track to move transversely. Because the faces are at the acute angle, there is only a component of, and not the entire, minimum wafer transfer distance extending in the direction of the footprint dimension line. The robot is positioned at least partly in the nest formed by the adjacent load lock faces without requiring rotation of the base of the robot on a vertical axis at the same time as the arms of the robot are moved in an extend motion during wafer transfer into the load lock. The footprint of the modules may be substantially reduced, in that at least one dimension of the footprint is minimized, yet the robot may operate with only relatively simple extend motion to transfer the wafers into the load locks, avoiding more complex motions that include both transverse motion (i.e., on a linear track) and rotate motion.

Granted: 2002-01-01
Abstract: A solenoid valve for a variable discharge fuel supply apparatus with which the relief performance and responsiveness are improved and which leads to miniaturization and reduces the working current.

Furthermore, it is possible to connect the outside of the valve to the high-pressure side of the fuel supply apparatus, to connect the passage to the low-pressure side, to use an annular valve seat surface, to bring the valve into contact with the valve seat only between the outside diameter of the seat surface and the inside diameter of the valve seat surface, to allow the flow passage to extend through the valve and pass close to the electromagnetic solenoid which transfers the valve on the downstream side of the valve, and to allow the valve seat to be a part separated from a valve holder.

Title: Separator for use in electrochemical cell devices
Inventor: GOZDZ ANTONI S
IPC: H01M50/426
Filed: 2000-11-08
Granted: 2002-04-21
Abstract: A separator for use in laminated multi-layer electrochemical cell device structures. The devices comprise positive and negative electrode layer members of polymeric matrix composition having the microporous polylefin membrane separator member interposed therebetween wherein the separator membrane includes a polymer coating layer. The separator is treated to provide a deposited coating of a primary plasticizer for the polymer coating layer. The device electrode and separator members are then assembled and laminated at a compressive force and temperature at which the plasticizer film softens the polymer coating of the separator member sufficiently to establish a strong interfacial bond with the matrix polymers of the electrode members and thereby form a laminated unitary cell structure. In another embodiment, the primary plasticizer comprises a component of the electrode polymeric matrix compositions. In either embodiment, the plasticizer subsequently volatilizes from the structure to further strengthen the interfacial bond, yet its temporary presence in the interfacial region of the multi-layer cell structure enables lamination of the cell members at a temperature below the pore-collapse temperature of the separator membrane, thereby preserving the thermal shut-down protection feature of the microporous separator.

Granted: 2002-07-21
Abstract: A chuck includes a generally cylindrical body and a plurality of jaws moveably disposed with respect to the body in communication with the body's axial bore. A generally cylindrical sleeve is rotatably mounted about the body in operative communication with the jaws so rotation of the sleeve in a closing direction moves the jaws towards the axis of the axial bore and rotation of the sleeve in an opening direction moves the jaws away from the axis. A bearing has a first race adjacent the body, a second race adjacent the sleeve and at least one bearing element disposed between the first race, and the second race. One of the first race and the second race defines a ratchet. The other of the first race and the second race defines a pawl biased toward the ratchet. The ratchet and the pawl are configured so that when the pawl engages the ratchet, the ratchet and pawl prevent the second race from rotating in the opening direction with respect to the first race.
