Filed: 1988-11-02
Abstract: PURPOSE:To prevent incorporation of hydrogen in a silicon nitride film and to improve the crack resistance property of the silicon nitride by forming the silicon nitride film by the reaction of silicon and nitrogen. CONSTITUTION:Argon gas which is introduced through an auxiliary cathode 36 is transformed into argon ions having positive charge in a plasma region 26. The ions are made to hit a silicon target 18 to which negative charge with respect to a counter electrode 14 is applied. Therefore, the silicon target 18 is sputtered, and silicon atoms and silicon molecules are driven out of the surface. Nitrogen which is introduced through a gas introducing port 24 and silicon are made to react, and a silicon nitride film is formed on the surface of a semiconductor substrate 60. Since the silicon nitride film is formed by the reaction of the silicon and nitrogen in this way, hydrogen is not incorporated in the silicon nitride film, crack resistance is not deteriorated and the device can be formed with homogeneous film quality.

Abstract: PURPOSE:To suppress superposition of low order higher harmonic components by reducing a voltage command value in conformity with the content of the drop of the input voltage of an inverter to make the ratio of the output voltage of inverter to the frequency variable. CONSTITUTION:Assuming that the voltage of AC power supply 1 is less than a set voltage, a subtract signal VPAT2 is output from an output circuit 8 and added to an output voltage feedback VFB, and a signal for suppressing the deviation between this added voltage and a voltage command VPAT1 is output from the AVR 11.
