Title: Data comparison AGC system for vsb receiver
Inventor: KRISHNAMURTHY GOPALAN
IPC: H04L27/06
Filed: 1997-10-06
Granted: 2000-09-11
Abstract: A technique and apparatus for developing AGC voltage in a receiver capable of receiving VSB signals that do not have the data symbol levels and the sync symbol levels related so as to produce the same average magnitude level. Successive portions of the signal are accumulated, stored and compared with the smaller of the samples to be used to develop the AGC voltage. By comparing the first and third of three successive samples, the effect of the larger than desired sync levels in the over-the-air VSB signals is completely eliminated.

Title: Code division multiplex communication equipment
Inventor: TSUBOUCHI KAZUO
IPC: H03H9/145
Filed: 1998-01-16
Granted: 1999-12-11
Abstract: To provide the code division multiplex communication equipment that has provision for a long spread code, is operated for RF and IF bands and easily changes a spread code with less power consumption. A correlation device 5 employs the switched current system and detects the correlation by current summation. A voltage/current converter V/IC 101 converts a voltage of a signal Vin received from a terminal T1 into a current Iin. CDF/F1021-102n (n is a natural number) are current flip-flop circuits and sample and latch the current Iin converted by the V/IC 101 in time series based on clock signals W1, W2. A switch matrix 103 changes a path through which an output current of the CDF/F1021-102n flows based on a pseudo random noise PN code. A current adder 105 adds output currents of a switch matrix 103 to take correlation between the input signal and the PN code.

Title: Plasma processing method for enhancing the silicon nitride passivation of semiconductor metal interconnects
Inventor: DU YOU-LUEN
IPC: H01L23/50
Filed: 1998-02-21
Granted: 2001-12-21
Abstract: A plasma processing method which is used in the metal interconnects of ultra large scale integrated circuit to form the silicon nitride passivation for improved plasma enhanced chemical vapor deposition; the process is conducted in a single plasma enhanced chemical vapor deposition reactor; after depositing the stress-releasing film of silicon oxide on the metal wiring, depositing the silicon nitride layer in plasma enhanced vapor deposition and then conducting the plasma processing step on the silicon nitride layer. With thinner silicon nitride layer, it can prevent the photoresist from falling into the voids of the silicon nitride passivation between metal wiring in short pitches and resulting in the erosion of the metal; using the plasma treatment with mixing gas containing He, Ar or both to densify the silicon nitride layer greatly reduces the pits causing the short circuits of inter-layer metal.
