IPC: H01L27/092
Filed: 1984-04-25
Abstract: PURPOSE:To reduce the parasitic capacitance and thus obtain an amplification circuit, an oscillation circuit, and the like of low power consumption by a method wherein the concentration of the semiconductor side surface region of an MOS type capacitor is more increased than that of the other. CONSTITUTION:A capacitance element with a conductor layer formed via insulation film is provided on the semiconductor region of the same conductivity type which has been set at a high concentration. For example, a p type well region 3 formed in an n type semiconductor substrate 2 and a gate region 8 formed above this well region via gate insulation film 7 are made as two terminals of a capacitor C0, and the gate capacitor existent therebetween is used. Then, a high concentration impurity region 12 is formed in the upper part of the well region 3 by implantation of a p type impurity such as boron from above the gate region 8 by ion implantation. Thereby, it becomes difficult that an inversion layer is produced immediately under the gate because of a high impurity concentration there; accordingly the capacitance value per unit area can be taken large, resulting in a construction with a small area. Consequently, the parasitic capacitance existent between the n type substrates can be reduced.
