Title: Semiconductor integrated circuit
Inventor: SHIRATO TAKEHIDE
IPC: H02H7/20
Filed: 1982-06-30
Abstract: PURPOSE:To prevent the gate breakdown of FET of a shallow diffused layer by a method wherein an impurity-diffused layer inserted and connected between a semiconductor element and input/output terminals is made deeper than the diffused layer of the element. CONSTITUTION:An SiO2 film 5 is provided on an Si substrate 4, a gate oxide film 8 and a poly Si gate are formed, and a source 7, a drain 6 and a resistance layer 15a are formed by implanting As ions to the depth of 0.4mum. Then, a mask being renewed, P ions are implanted to the depth of 0.6-0.8mum to form a diffused layer 15 for resistance. Since the diffused layer 15 is formed sufficiently deep in this constitution, a curvature 16 is made large, no concentration of electric fields is thereby caused, and junction capacitance is also increased. Accordingly, an overvoltage or a high-voltage pulse caused by static electricity, which is applied to a pad 1, is damped enough by the resistance layer and thus causes no breakdown of the diffused layer 15. The electrostatic resistance of 100V or above can be obtained only by an increase in junction capacitance.

Abstract: PURPOSE:To enable to draw a pattern in an accurate manner by a method wherein material is divided into a circular arc-shaped elongated region or contracted region from its height distribution, and the irradiation position of a beam is corrected based on the amount of elongation or contraction of the chip which is present on the respective region, thereby enabling to eliminate the deviation of the beam shot position generating due to the deflection of material. CONSTITUTION:The electron beam emitted from an electron gun 2 is focussed by an electron lens on the material 1 held by a material holder 4 and, at the same time, the shot position is controlled by the deflection force of a deflector 5. On this deflector 5, the prescribed positional signal whereon the amount of signal corresponding to the amount of correction based on the elongation or contraction of material is superposed is sent from a CPU through the intermediary of an amplifier 7. To be more precise, said CPU 6 supplies before performing an exposure the memorized amount of elongation or contraction of the chip of material to be exposed to the deflector 5 in superposition to the intrinsic shot position signal. Accordingly, the beam can be shot at the prescribed position of the material 1.

Filed: 1990-04-27
Abstract: PURPOSE:To softly place an object at an end position by driving a DC motor again after stopping to drive it for a prescribed time at the time of arrival of the object at a position just before the end position with respect to a DC motor type positioning device. CONSTITUTION:An output shaft 15 of a DC motor 13 of the positioning device is connected to a variable intake control valve 11 through a power transmission path 16. In this constitution, the DC motor 13 is driven to control the degree of opening of the control valve 11. The motor speed of the DC motor 13 is low at the time of driving start. Consequently, a valve body of the variable intake control valve 11 is prevented from being driven to overrun the full open position or the full close position when reaching the full open position or the full close position from the just preceding valve opening degree position. Consequently, the frequency in collision to stoppers which prescribe the full open position and the full close position is reduced to softly position the object.
