Patent JP-S63181423-A (JP)
Title: Manufacture of semiconductor device
Inventor: GOTOU NOBUSATO
IPC: H01L29/78
Filed: 1987-01-23
Abstract: PURPOSE:To prevent deterioration of electric characteristics, by implanting dopant ions into a first conductive material on an insulation film including a contact hole, depositing a second conductive material on a nitride of a high- melting metal deposited thereon, etching the same and diffusing a dopant into the second conductive material. CONSTITUTION:A dopant diffusion layer 22 having the opposite conductivity type to that of a semiconductor substrate 21 is formed on the surface of the substrate 21. An insulation film of an oxide for example is formed thereon and a contact hole 24 is formed by the RIE process or the like. After a polycrystalline silicon film 25 is deposited thereon, mixing implantation 30 is performed by using arsenic for example. A titanium nitride film 26 is formed and then a polycrystalline silicon film 27 for example is deposited thereon and etched away by the RIE process or the like. Then, the titanium nitride film 26 thus exposed is etched away. Phosphorus is diffused in the polycrystalline silicon layers 25 and 17. In this manner, since the titanium nitride film 26 serves as a barrier during the diffusion of phosphorus, deterioration of electric characteristics can be prevented.

Abstract: PROBLEM TO BE SOLVED: To transmit an information signal at high speed by transmitting the information signal while converting code streams so as to accelerate the speed of that transmission, and converting the code streams of the information signal to be original at a reception part. SOLUTION: When using spread spectrum modulation, at a transmitter 1, the code streams of the inputted information signal are converted by a code converting part 2 so as to accelerate the transmission speed. Afterwards, signal modulation, 1st-order modulation such as four-phase modulation and spread spectrum modulation due to spreading codes are performed, and the information signal is converted to a radio frequency band and transmitted from a transmission antenna 5 by a radio transmission part 4. On the other hand, the signal of radio frequency band received by a reception antenna 7 at a receiver 6 is converted to a base band signal by a radio reception part 8, afterwards, 1st-order demodulation such as spectrum demodulation is performed by a signal demodulation part 9, and the signal is converted to the original information signal by a code converting part 10.  At such a time, at the converting part 10, the code streams of the information signal are demodulated to code streams so that the transmission speed can become original speed.

Title: Chattering eliminating circuit
Inventor: TAKAHASHI AKIO
IPC: H03K5/1252
Filed: 1982-02-03
Abstract: PURPOSE:To eliminate chattering at all times and to decrease the number of component parts to increase the packing efficiency of a circuit substrate, by discriminating the chattering at a mechanical mobile contact in the 1-cycle period of the reference clock and transmitting an output signal after it is stabilized. CONSTITUTION:A switch SW1 is connected to a light emitting diode LD2 via a diode D3. Then the current supplied from the voltage V1 is supplied to a chattering eliminatng circuit IC via the diode LD2 and a resistance 13 when the switch SW1 is turned on. The presence or absence of chattering is decided within the reference clock (1 pulse) that is decided by a capacitor C3 of the circuit IC and the internal resistance of the circuit IC. When no chattering exists, a signal is delivered in response to an input signal and after a prescribed clock. The same procedure is carried out also when the SW1 is turned off. Thus a stable signal having no chattering is delivered at all times regardless of fluctuations V1, V2 and V3, etc.
