Title: Manufacture of semiconductor device
Inventor: INAGAKI TAKETOSHI
IPC: H01L21/76
Filed: 1990-03-20
Abstract: PURPOSE:To enable thickness of an element substrate to be uniform by forming an oxidizable film on a bottom surface of a groove reaching an insulation layer of a semiconductor layer and an oxidation-resistant film on the semiconductor layer other than the bottom part for allowing the oxidizable film to be oxidized and eliminating the oxidation-resistant film, and then grinding the semiconductor layer until this oxide film is detected. CONSTITUTION:A groove 8 which reaches an insulation layer 7 from a surface of a semiconductor layer 6 is formed, an oxidizable film 9 is formed on a bottom surface of the groove 8, and an oxidation-resistant film 10 is formed on the semiconductor layer 6 other than the bottom part of the groove. Then, after the oxidizable film 9 which is exposed at the bottom part of the groove is oxidized for forming an oxide film 11, the oxidation-resistant film 10 is eliminated and a semiconductor layer 6a is ground until an oxide film 11 is detected. Thus, by making thinner a semiconductor substrate 6a (which becomes an element substrate) with the oxide film 11 which is formed at the bottom part of the groove 8 as a stopper, film thickness of the element substrate 6 can be made uniform regardless of fluctuation in thickness of the semiconductor substrate 6a which becomes the element substrate.

IPC: H05K1/02
Filed: 1995-03-29
Abstract: PURPOSE: To reduce radiation noise by restraining magnetic field generated by a high frequency current without restraining a high frequency current itself which serves as a noise source. CONSTITUTION: One signals circuit is constituted of two branched signal wiring patterns 11, 12 which are parallel, branched signal wiring patterns are formed in opposite positions of two layers with a layer wherein GND patterns 13a, 13b are formed between and each thereof corresponds to the GND patterns 13a, 13b formed in a following layer inside. High frequency currents 15a, 15b flow almost vertically to a counter surface from the signal wiring patterns 11, 12 wherein a rapid signal flows to the GND patterns 13a, 13b so that directions thereof are opposite to each other. Since generated magnetic fields 16a, 16b also become opposite, they cancel each other and generation of electromagnetic wave 17 decreases and noise radiated to an outside also decreases.

Title: Radio communication system and transmitter and receiver used for the system
Inventor: KONDO SEIJI
IPC: H04J13/16
Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To prevent reduction in the transmission capacity, even when a frame having a code error is retransmitted in a CDMA system in particular by making a transmitter read the information to be transmitted again out of a storage part to output it, in response to a retransmission instruction and then transmitting the information to be retransmitted with the information to be transmitted at the same time. SOLUTION: A retransmission request frame that is fetched from a receiver 57 is multiplied by a 2nd diffusion code via a 2nd multiplier 58 and decoded at a decoding part 59. Receiving a retransmission directive from a control part 12, a coding part 1 reads the corresponding frame out of a storage part 2 and outputs it to a retransmission channel 7. Meanwhile, the part 1 is carried on the transmission of information via a transmission channel 3. The retransmission frame outputted to the channel 7 is multiplied by a 3rd diffusion code via a 3rd multiplier 9 and inputted to an adder 54. The adder 54 adds a normal transmission frame, sent from the channel 3 to the retransmission frame sent from the channel 7. Then both frames added together are transmitted via an antenna 56.
