Abstract: PURPOSE:To unnecessitate the working process for formation of a contact hole, and to eliminate the disconnection of wire of an electrode wiring by a method wherein a protruding part is provided on a semiconductor substrate, and the impurity diffusion layer formed on the protruding part is brought into contact with the electrode wiring. CONSTITUTION:First, a protruding part 3 is formed on a semiconductor substrate 1. Then, a gate insulating film 4 is formed, and a gate electrode 5 is formed on the semiconductor substrate 1 excluding the protruding part 3. After the whole area of the protruding part 3 has been formed into an N-type impurity diffusion layer 8 by obliquely implanting ions and conducting a heat treatment, an interlayer insulating film 9 is formed. Subsequently, after an etching treatment has been conducted to expose the part which becomes the part of contact of the N-type impurity diffusion layer on the upper surface of the protruding part 3, an electrode wiring 12 is formed on the whole surface of the semiconductor substrate 1, and the upper surface of the protruding part 3 and the electrode wiring 12 are brought into contact with each other. As the impurity diffusion layer 8, formed on the protruding part 3, and the electrode wiring 12 are brought into contact, the formation of a contact hole is unnecessitated, and the disconnection of wire on the electrode wiring 12 can be eliminated because an extreme stepping is not generated.

Filed: 1996-07-16
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption of an infrared ray signal receiver by operating a data demodulation section only for a period when an infrared ray signal is actually received. SOLUTION: When stating to receive an infrared ray signal IN, a signal DETECT goes to '1' and an operating clock CLK' is applied to a data demodulation circuit 144. When the reception of the infrared ray signal IN is finished and consecutive data '0s' are in existence from a time (threshold time) designated by a timer 147 after the reception of the final data '1', the signal DETECT goes to '0' and the application of the operating clock CLK' to the data demodulation circuit 144 is inhibited. Thus, the operating clock is applied to the data demodulation circuit 144 by the reception interrupt of the infrared ray signal, and when the infrared ray signal is not received for a prescribed time by the timer 147, then the operating clock to the data demodulation circuit 144 is stopped.
