Title: Manufacture of semiconductor device
Inventor: OKAMOTO YUTAKA
IPC: H01L29/78
Filed: 1990-09-27
Abstract: PURPOSE:To prevent the deterioration of a gate insulating film of a buried contact section by etching the gate insulating film by using the first conductor film as a mask after implanting the ion of such an element that accelerates the etching speed of the gate insulating film into the gate insulating film by using a resist pattern as a mask. CONSTITUTION:After implanting the ion of such an element that accelerates the etching speed of the gate oxide film 4 of a buried contact section by using a resist pattern 6 as a mask, the oxide film 4 is etched by a wet etching method. Accordingly, the oxide film 4 can be removed by etching in a short time. Therefore, deterioration of the gate oxide film 4 below a polycrystalline Si film 5 can be prevented effectively even when the size of the buried contact is reduced, since the etching liquid percolates to the film 4 through the grain boundary of the film 5. As a result, stable buried contact can be realized.

Title: Circuit for generating voltage
Inventor: AIMOTO YOSHIHARU
IPC: H01L21/822
Filed: 1991-10-07
Abstract: PURPOSE:To prevent an output voltage from exceeding a fixed voltage when boosting the voltage fed from the external, by providing a boosting circuit for boosting the voltage fed from the external, and by providing first and second MOS field effect transistors. CONSTITUTION:Since the supplied voltage of a power supply is applied to the gate and drain of an NMOS transistor N7, the initial value of an output voltage Vout is lower than the supplied voltage of the power supply by the threshold voltage of the NMOS transistor N7. At this time, an NMOS transistor N8 is in OFF-state. Then, when the output voltage Vout is increased by a boosting circuit 5 and reaches the threshold voltage of the NMOS transistor N8, which is added to the supplied voltage of the power supply, the NMOS transistor N8 is turned on. This acts such that the output voltage Vout is not higher than the threshold voltage of the NMOS transistor in a switching circuit, which is added to the supplied voltage of the power supply. Thereby, when boosting the voltage fed from the external, the output voltage can be prevented from exceeding a fixed voltage.
