Title: Method for manufacturing ultra-shallow junction metal oxide semiconductor transistor
Inventor: TZENG HUNG-HUEI
IPC: H01L29/772
Filed: 2000-11-10
Granted: 2001-12-01
Abstract: The present invention is related to a kind of method for forming ultra-shallow junction metal oxide semiconductor transistor and contains the following steps. At first, a semiconductor substrate on which the related positions of gate region and source/drain region have been defined is prepared. Then, an ion metal plasma (IMP) deposition method is used to deposit a silicon layer on the source/drain region and the upper surface of gate in a direction perpendicular to semiconductor substrate, in which the silicon layer is not deposited on the sidewall of gate region in this step. An LDD ion implantation is implanted inside the IMP silicon layer and is followed by performing a thermal oxidation process to partially oxidize the IMP silicon layer and the sidewall of gate so as to assure the separation between the gate and source/drain region, and to form the LDD region. After that, the spacer process is conducted. At the same time, the oxide layer on IMP silicon layer is also etched to expose the IMP silicon layer. Heavily doped ion implantation method is used to implant conductive impurities into semiconductor substrate. Self-aligned method is then used to form metal silicide layer on the source/drain region and the upper surface of gate.

Abstract: A method for creating signal directionality in electronic circuits is disclosed. This invention describes a method for achieving directionality in an electronic circuit with an input side having a signal source and an output side with a load comprising detecting the current passing through the load on the output side, bypassing a portion of the current passing through the load on the output side, and feeding the bypassed portion of the current on the output side to the input side to achieve directionality. Specifically, unidirectionality in an electronic circuit is accomplished by applying feedback such that the impedance looking into the input of the amplifier is increased. These methods are particularly applicable to negative resistance amplifier circuits.

Title: Method for calibrating timing of an integrated circuit tester and an interconnect system
Inventor: MILLER CHARLES A
IPC: G01R31/319
Filed: 2001-04-03
Granted: 2002-12-01
Abstract: A timing calibration system for a wafer level integrated circuit (IC) tester is disclosed. To adjust a compare calibration delay of each tester channel, an interconnect system sequentially connects the tester channels to interconnect areas on a ""calibration"" wafer instead of to the IC on the wafer to be tested. Each interconnect area provides a path linking a channel to be calibrated to a spare channel. With the programmable drive delay of the channel being calibrated and the programmable compare and compare calibration delays of the spare channel set to standard values, the drive calibration delay of the channel being calibrated is adjusted so it sends a test signal edge to the spare channel close to when the spare channel samples it.

Granted: 2004-10-01
Abstract: When a predetermined key (22) is depressed in a power OFF state, status memory (33) stores a status signal and a mask circuit (31) outputs an ON signal. By the ON signal, a power circuit (26) turns on the system power source. A processor (28) starts to operate, accesses the status signal, and starts up a predetermined application program. When the predetermined key is depressed in a power ON state, the mask circuit does not output the ON signal. A controller (27) detects the operation of the predetermined key and outputs a signal for instructing the predetermined application program to be started up to the processor. When a power switch is depressed, the power circuit turns on the system power source. The processor starts to operate and accesses the status signal. Since no status signal is stored, the processor does not start up the predetermined application program.
