Title: Process for manufacture of a P-channel MOS gated device with base implant through the contact window
Inventor: KINZER DANIEL M
IPC: H01L21/331
Filed: 1998-02-03
Granted: 1999-08-21
Abstract: An MOS-gated power semiconductor device is formed by a process that uses a reduced number of masking steps and minimizes the number of critical alignments. A first photolithographic masking step defines the body or channel region and the source region of each of the cells. A second photolithographic step is aligned to a small central area above the source region of each of the cells or strips, the only critical alignment in the process, and is used to define openings in a protective oxide layer which, in turn, masks the etching of depressions in the substrate surface and the formation of a contact region. An isotropic etch undercuts the protective oxide to expose shoulders at the silicon surface of the chip which surround the etched holes. A conductive layer fills the holes and surrounding the source regions at the silicon surface. The conductive layer is sintered at a temperature that is sufficiently high to achieve low contact resistance between the metal and body regions but is low enough to be tolerated by the conductive layer.

Title: Excimer laser with pulse multiplier
Inventor: MORTON RICHARD G
IPC: H01S3/225
Filed: 1999-09-04
Granted: 2001-05-16
Abstract: An excimer laser with optical pulse multiplication. A pulse multiplier optical system receives the laser output beam and produces a multiplier output beam having a larger number of pulses, each with substantially reduced intensity values as compared to the laser output beam. The present invention is particularly important as an improvement to the ArF excimer laser to reduce two-photon absorption damage to optical equipment in lithography machines. For damage mechanisms involving two-photon processes, such as the compaction and solarization of fused silica in the DUV spectral region, a factor of 4 reduction in peak power decreases the quantity of two photon absorption damage done by the synthesized 4-pulse burst by a factor of about 16 compared to delivering all of the energy in the single pulse emitted by the laser. This is useful method of prolonging the lifetime of very expensive beam delivery systems such as those used in photolithography stepper systems without reducing the total dose available at the wafer. In preferred embodiments, the pulse multiplier system is contained in a module which can be pre-aligned and quickly installed on the excimer laser.

Title: Radio communication system and method of operating the same
Inventor: BAKER MATTHEW PETER JOHN
IPC: H04B7/005
Filed: 1999-12-30
Granted: 2001-11-11
Abstract: A radio communication system has means for ensuring that power control of a communication channel has been established before the transmission of data. This is done by delaying initial transmission of a data channel (either at the start of a transmission or after a pause) until after the initial transmission of control channels. In one embodiment the transmission of a data channel can be delayed until adequate power control has been established. These techniques overcome the problem that data transmissions at the start of a data channel are likely to be corrupted if their power level is too low, or to generate extra interference if their power level is too high. The radio communication system also has means for improving power control of a communication channel for the transmission of data after an interruption in the transmission. This is done by applying power control in steps of variable size at the start of a transmission, using a large step size initially which is reduced as the power approaches a target value. In one embodiment the step size is reduced when the sign of a power control command reverses, while in another embodiment the step size is reduced after a predetermined time. These techniques reduce the time taken for power control to be established, thereby addressing the problem that data transmissions at the start of a data channel are likely to be corrupted if the power level is too low, or to generate extra interference if the power level is too high.
