Title: Manufacture of semiconductor device
Inventor: ONISHI SHIGEO
IPC: H01L29/43
Filed: 1989-01-06
Abstract: PURPOSE:To prevent the unstable tungsten oxide film from being produced by a method wherein a gate electrode comprising tungsten on the surface thereof is formed and after nitrifying the surface of the gate, a channel region is formed below the gate electrode by implanting ions from the surface side. CONSTITUTION:A tungsten gate electrode can be formed by depositing a tungsten film on a substrate, e.g., by sputtering process to be etched into specified pattern by, e.g., reactive ion etching process. The gate electrode is nitrified by heating in oxygen excluded NH3 gas. Later, a channel region is formed below the gate electrode by implanting ion from the gate electrode surface side. That is, the tungsten nitride film on the surface of the formed tungsten gate electrode shields the ion directed during the ion implanting process to prevent the ion-implantation into the channel region from occurring so that the deterioration of the tungsten gate electrode due to the surface oxidation may be prevented from occurring during the formation of an interlayer insulating film and annealing process.

Abstract: PROBLEM TO BE SOLVED: To enhance frequency stability and to reduce power consumption by detecting a new frequency deviation, calculating frequency deviation correction data to make the frequency deviation zero and controlling an oscillated frequency of a master clock oscillation section. SOLUTION: A measurement control section 3 activates a frequency f0±Δf of a master clock for t-sec for the measurement by a frequency measurement section 2. The newest measurement value (c) and the result of measurement measured for the t-sec when the frequency deviation ±Δf detected by a frequency deviation detection section 4 is zero are subject to subtractor processing to detect the newest frequency deviation ±Δfd. Then a correction table 5 is used to calculate frequency deviation correction data to make the frequency deviation ±Δf zero, an oscillated frequency control section 6 converts the data into the frequency control signal to control the oscillating frequency of a master clock oscillation section 1 so as to make the frequency deviation ±Δf zero.  The frequency deviation ±Δf of the master clock oscillation section is reduced by repeating the operation to enhance the frequency stability and to reduce the power consumption.
