Abstract: PURPOSE:To reduce effectively the short channel effect caused by shortening of gate by installing the buried region of inverse conduction type to the source region and the drain region in the position which is close to the channel region in the source/drain region and deeper than the position of the channel region. CONSTITUTION:The N<+> type source region 4 and the N<+> type drain region 5 are formed on bath sides of the channel region 3 directly under the gate electrode 2. These source region 4 and drain region 5 can be formed by the ion injection, but the larger injection energy is applied than that of the formation of the channel region 3. The P type buried region 6 is formed in the place which is close to the channel region in the N<+> type regions 4 and 5 and deeper than the channel region 3. This P type buried region is formed also by the ion injection and Zn or Be, for example, is applied to the ion for injection. Thus the high impurity density region of source and drain can be separated by the P-N junction, so that the leak current through the substrate can be extremely reduced.

Abstract: PURPOSE:To form a passivation film without electric damage and make it possible to form a high-breakdown-voltage, fine diffusion region such as an emitter by simultaneously forming the passivation film, which comprises a silicon oxide film and a selective oxide film made by selectively oxidizing polysilicon, and an electrode layer made of the polysilicon. CONSTITUTION:A first passivation film 11 comprises a silicon oxide film 11a and a selective oxide film 11b which is formed by selectively oxidizing polysilicon 6 with a silicon nitride film used as a mask. The selective oxide film 11b of the first passivation film 11 is made by selectively oxidizing the polysilicon 6 as an emitter electrode by the local-oxidation-of-silicon (LOCOS) method with the silicon nitride film used as the mask, therefore, the polysilicon 6 does not need to be patterned by dry etching such as plasma etching and reactive ion etching. That is, the polysilicon 6 can be formed self-alignedly by the LOCOS method. Hence the silicon oxide film 11a formed on the surface of an n<-> type silicon substrate 1 is not electrically damaged by dry etching.

Abstract: PURPOSE:To reduce the value of a position data memory and to improve the processing efficiency of a controllable controller by giving a command to a servo motor circuit after inverting the value of the position data memory by an extent equal to the count value of a counter or the value of an external input signal. CONSTITUTION:When a servo motor 7 is driven, a position data address of the motor 7 is designated together with an optional count value. The moved variable of the motor 7 is set at such value that can invert the value designated by the designated position data address by an extent equal to the frequency of the count value. Then a moved variable corresponding to a fixed extent is previously stored in a position data memory 3 and the traverse frequency of a coil is previously set to a counter. Thus the motor 7 performs the inverting actions in response to the due frequency and at the same time the value of the designated counter is counted up. As a result, the drive of a servo motor performing a fixed winding action can be simply controlled.
