Title: Capacity detecting device
Inventor: YOSHIKAWA KAZUO
IPC: G06F3/03
Filed: 1985-10-31
Abstract: PURPOSE:To improve the noise resistance of a capacity detecting device which uses a frequency negative feedback system circuit similar to a PLL by making an oscillation period effective only when the absolute value of an LPF output is smaller than a specific value. CONSTITUTION:The output of an APF 22 and the sine-wave output of a VCO 21 are supplied to an LPF 24 through a phase comparator 23. The output of this LPF 24 is inputted to a window comparator 25 as a phase difference signal absolute value decision means. This comparator 25 detects whether the output of the LPF 24 is within a specific range or not. When the output is within the specific range, the capacity connected to a terminal 28 is detected. When the output is not within the range, it is decided that a noise is mixed and the capacity detection operation is stopped for a specific time until the noise disappears. Consequently, the noise resistance is improved.

Title: Method of forming oxide film
Inventor: KIMURA SHINICHIRO
IPC: H01L21/316
Filed: 1984-11-21
Abstract: PURPOSE:To obtain a method of forming an oxide film having excellent boundary characteristics and electric characteristics without heating the substrate temperature by emitting a light absorbed efficiently to the grown film simultaneously with oxygen plasma. CONSTITUTION:When a microwave (mu-wave) discharge is used, the microwaves generated by magnetrons 1, 1 are led to quartz cylindrical discharge tubes 1, 8, which generate plasmas 1, 9. Electrons slightly presented in gas in a magnetic field move in a cyclotron motion. When the frequency coincides with that of the microwave to be emitted, an electron cyclotron resonance phenomenon occurs, the electrons absorb the energy of the microwave to efficiently discharge. The light to be efficiently absorbed to the oxide film uses infrared ray generated from a carbon dioxide gas laser. Thus, an SiO2 film is grown on Si at 500 deg.C of 1/2 of the conventional one, and when the light near the absorbing peak of the SiO2 is emitted, the growing of the oxide film becomes remarkable, the infrared ray emitted to the substrate is efficiently absorbed as the thickness increases, and applied as a method of forming the oxide film on an element not performed at high temperature.
