Title: Manufacture of semiconductor device
Inventor: TAKAGI HIDEO
IPC: H01L23/52
Filed: 1986-03-18
Abstract: PURPOSE:To prevent a silicide film or a polysilicon film generated at a step from decreasing in width or being disconnected by depositing an oxidation preventive film on the silicide film, and allowing the oxidation preventive material to remain only on the step. CONSTITUTION:An SiO2 film 12 is formed on a base 11, a polysilicon film 13 and a silicide film 14 are grown on the base to form wirings of a polysilicon/ silicide layer structure, and the polysilicon/silicide wirings form a step at the end of the film 12. A silicon nitride film 16 is grown by chemical vapor growth, and etched until the silicon nitride film of the flat portion is removed by RIE. Then, since the thickness of the film is larger than that of the flat portion at the step, silicon nitride 16a remains on the step. The SiO2 film is formed on the film 14 by thermal oxidizing, but the step is masked by the silicon nitride 16a. Accordingly, the silicide film of the step is not oxidized. Thus, it can prevent the silicide film or the polysilicon film of the step from decreasing in width.

IPC: F28F3/04
Filed: 1986-03-17
Abstract: PURPOSE:To prevent the defect generation of a product and to reduce the cost by adhering the minimum necessary brazing filler metals to the apex part on the outer face of a corrugated fin, then by heating and brazing by combining with a separate plate. CONSTITUTION:A brazing filler metal 4 is adhered with controlling the adhesion quantity by spraying or brushing, etc. on the outer face apex part 1a of a corrugated fin 1, and the minimum necessary brazing filler metal 4 is adhered on the abutting plate to the corrugated fin 1, spacer bar, side bar 3, etc. as well.

Title: Clock reproducing circuit
Inventor: MATSUOKA IKUO
IPC: H03K3/86
Filed: 1979-05-17
Abstract: PURPOSE:To perform the clock reproduction with the reduced phase jitter by detecting the level at the output point of the surface wave filter and then giving the control to the positive feedback amount in order to secure the constant output level. CONSTITUTION:The output which was filtered through elastic surface wave filter 1 and then received an integer-fold cycle delay is amplified 2 and then supplied to analog adder 3. For the two inputs of adder 3, the same phase is secured for the output given from input terminal 4 and that from amplifier 27 and then the analog addition is carried out to be then supplied again to filter 1. This loop of one circulation forms the positive feedback loop at the central frequency region and then detects 6 the level at the output point of filter 1 to give the control to the positive feedback amount. Accordingly, the clock reproduction is possible with the reduced phase jitter and even with the zero continuation of the code pulse of the input signal by giving the control to the positive feedback amount in order to secure the constant output level.
