Title: System and method for crystal growth
Inventor: SARAYAMA SHOJI
IPC: H01S5/00
Filed: 1998-06-17
Abstract: PROBLEM TO BE SOLVED: To provide a system and a method for crystal growth of good quality GaN semiconductor crystalline film with low-cost and moreover with simple constitution and a small number of nitrogen holes. SOLUTION: A crystal growth system 20 has a substrate 27 between a support 28a of a susceptor holder 28 and a susceptor 25. While power is supplied to a coil 33 for induction heating to generate eddy current in the susceptor 25 and the substrate 27 is heated to a predetermined high temperature, a material gas is supplied from a gas supply tube 29, that is attached to a flange 22 at the bottom side of a reaction chamber 21 and has an ejection port located under the exact center of the substrate 27. A compound film 32 containing nitrogen is attached to the peripheral surface of the susceptor holder 28, the outer surface of the support 28a, and the end portion of a gas feeding tube 31 conically opened under the substrate 27. This compound film 32 is also heated to a temperature higher than the decomposition temperature.  The compound film 32 containing nitrogen is decomposed, and the partial pressure of nitrogen near the substrate 27 is increased. Therefore, good quality GaN semiconductor crystalline film can be deposited on the surface of the substrate 27, even though the portion of nitrogen material in the material gas is small.

Abstract: PURPOSE:To suppress penetration by a bird's beak and to render microstructural with facility an element isolating region by a method wherein a gap is provided in a pad oxide at the lower end of a silicon nitride film and the gap is filled with a polycrystalline silicon film. CONSTITUTION:A silicon nitride film 13 is formed on the entire surface of a pad oxide film 12, and the silicon nitride film 13 is then subjected to etching. A photoresist film and the silicon nitride film 13 patterned in said etching process serve as a mask in an ion implanting process, which results in a channel stop layer 14. A process follows wherein over-etching is accomplished for the providing of a gap 15 in the pad oxide film 12 at the lower end of the silicon nitride film 13, with the silicon nitride film 13 serving as an etching-resistant mask. On the entire surface of a semiconductor substrate 11, a polycrystalline silicon film 16 is deposited, filling up the gap 15. The polycrystalline silicon film 16 is then subjected to thermal oxidation for conversion into a silicon oxide film 17.

Title: Digital transmissionsystem integrated with service
Inventor: BUARUDEMAARU HAUKU
IPC: H04Q11/00
Filed: 1981-11-24
Abstract: A service integrated transmission system for transmitting, over a light transmission path, digital signals having a transmission band whose upper limit frequency corresponds to the maximum bit rate of the signals to be transmitted, the transmission being effected by simultaneously transmitting, over the transmission path, digital signals having a high bit rate only in an upper part of the transmission band and digital signals having a low bit rate only in a lower part of the transmission band. The system includes a transmitter at one end of the path which separately multiplexes low bit rate signals into a narrowband signal and high bit rate signals into a broadband signal, combines those multiplexed signals, and modulates a light source with the combined signal. A receiver at the other end of the path converts the modulated light signal into a demodulated electrical signal, separates the two multiplexed signals, and then demultiplexes each of the latter signals.

Abstract: PURPOSE:To reduce the coefficient of variation of the delay time of a semiconductor integrated circuit against a temperature change to about half as compared with the conventional example by providing the first capacity electrode composed of a resistance element and the second capacity electrode composed of a conductive layer below an insulating film. CONSTITUTION:A polycrystalline silicon film 105 having a fixed width is formed in a zigzag form in an element area divided by a field insulating film (element separating insulating area 103) formed by selectively oxidizing the surface of a P-type silicon substrate 101 through an insulating film 104.

The film 109 is connected constant-potential supplying terminals for earthing, etc., and signals inputted from one end of a resistance element of a polysilicon silicon film are outputted from the other end after they are delayed in time by means of an RC distribution constant circuit. Since the resistance element is also used as the first electrode, this delay element can be reduced in occupying area as compared with the conventional example equipped with a separate resistance and capacity elements.
