    摘要: An MIS transistor manufacturing method which can prevent unwanted diffusion of extensions caused by the drive to the source/drain so that the diffusion of the source/drain and the diffusion of the extensions can independently be controlled so as to obtain optimum structure for each. Source/drain are formed by ion implantation using, as a mask, L-shaped silicon nitride films formed on sides of a gate electrode and silicon oxide films covering the silicon nitride films. The silicon oxide films are then removed leaving the silicon nitride films. Impurity ions are then ion-implanted into the main surface of the silicon substrate through the silicon nitride films. Since the silicon nitride films are thicker in the vicinity of the gate electrode and thinner in the vicinity of the source/drain, this process forms extensions penetrating under the gate electrode for a small distance.

    摘要: In a method of manufacturing a semiconductor device capable of reducing gate resistance by increasing the width of a conductive layer formed on a gate electrode without increasing the gate length, an extension is formed in an upper surface of a silicon substrate, and thereafter a silicon oxide film and a silicon nitride film are deposited on the overall surface. Then, the silicon nitride film and the silicon oxide film are anisotropically etched in this order. Then, another silicon oxide film is deposited on the overall surface and thereafter anisotropically etched. Then, ion implantation is performed through a gate electrode and a side wall serving as masks, to form an impurity region. Silicon is grown under conditions having selectivity for a silicon oxide film, to form a silicon growth layer. Then, cobalt is deposited on the overall surface and thereafter heat treatment is performed to form a cobalt silicide layer. Thereafter unreacted cobalt is removed.
