Title: Manufacture of semiconductor device
Inventor: WATABE KIYOTAKA
IPC: H01L21/336
Filed: 1988-09-16
Abstract: PURPOSE:To avoid the degradation of a transconductance by a method wherein polycrystalline silicon, high melting point metal or its silicide is used as the material of a member on the side wall of a gate electrode which is a part of an ion implantation mask for obtaining an LDD structure and, further, the material is left on the side wall of the gate electrode. CONSTITUTION:After a field oxide film 2 is selectively formed on the main surface of a p-type silicon substrate 1, a gate electrode 3 is formed. After an insulating film 5 is formed on the surfaces of the gate electrode 3 and the substrate 1, a polycrystalline silicon film 6 is formed on it so as to cover the whole surface of the substrate 1. The polycrystalline silicon film 6 is so removed as to be left on the side wall of the gate electrode 3 by anisotropic etching. Arsenic or phosphorus ions are implanted with a relatively high concentration by using the gate electrode 3 and the remaining part of the polycrystalline silicon film as a mask. Even if hot carriers are injected into the gate side wall part on the drain side, they can be drained out of a drain electrode.

Abstract: PURPOSE:To improve the job efficiency and to reduce the cost of an entire set by providing a control circuit correcting a free-run frequency generated from a VCO (voltage controlled oscillator) in response to a count of a counter circuit to the circuit. CONSTITUTION:A counter circuit 23 counts a free-run frequency of a VCO 3 of the multiplexer circuit 14 based on a trigger pulse. When the count is higher than an upper limit of a predetermined range, a controller 24 changes a control signal applied to the VCO 3 of the multiplexer circuit 14 to adjust the VCO 3 so as to decrease the free-run frequency of the VCO 3.
