Filed: 1996-02-27
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device which enables adjustment of resistance value without causing any increase in temperature of a resistor and without generating excessive current concentration and microcrack in the resistor due to trimming, and manufacture thereof. SOLUTION: After an impurity diffusion layer 2 is formed on the surface of a single crystal silicon substrate 1, a silicon oxide film 3 is deposited on the impurity diffusion layer 2 and the single crystal silicon substrate 1. A contact hole is formed in the silicon oxide film 3 on the impurity diffusion layer 2 by photolithography and etching techniques, and a wiring layer 5 is formed in the contact hole 4. Then, the wiring layer 5 is irradiated with laser beams for trimming while the resistance value of a resistance element is measured. The contact resistance value is increased by reducing the contact area between the impurity diffusion layer 2 and the wiring layer 5, so that the resistance value is adjusted to a desired value. Finally, a protective film 6 is formed thereon except for at least part of the wiring layer 5.

Title: Tape drive control method of video tape recorder
Inventor: KONISHI SHIYUUICHI
IPC: G11B15/61
Filed: 1984-03-01
Abstract: PURPOSE:To attain the highly precise adjustment of tape driving by reducing the waveform distortions produced at the joints of audio output waveforms. CONSTITUTION:In the record and reproduction modes, the waveform distortions are produced at the joints of audio output waveforms since a rotary audio head is shifted by B in the head scan direction when the locus of the audio head is changed by A and therefore the time axis of a reproduction frequency is changed by the azimuth of the audio head. Then a fixed frequency is recorded previously to a standard tape by making use of the principle of said generation of waveform distortion. The recorded frequency is reproduced when the VTR tape drive is controlled. At the same time, the audio output waveform is observed by an oscilloscope and the tape drive posts, etc. are controlled to reduce the waveform distortion. In such a way, highly precise adjustment of tape running is obtained.
