Patent JP-S60194568-A (JP)
Title: Semiconductor ic device
Inventor: OKUYAMA KOUSUKE
IPC: H01L29/417
Filed: 1984-03-16
Abstract: PURPOSE:To secure the effect channel length by reducing the creeping of the source and drain regions to the region where the channel is to be formed, by a method wherein impurities are introduced by providing a side wall at both sides of a gate electrode. CONSTITUTION:After formation of a conductive layer 5 of the first layer provided on a required upper surface part of an insulation film 4, an Si oxide film 6A is so formed as to cover it. When the Si oxide film 6A is kept being etched by a uniform film thickness from its upper surface, the side wall 6 by self-alignment is formed. Next, using the conductive layer 5 and the side wall 6 as a mask for impurity-introduction resistance, N type impurities are introduced to the main surface of the substrate 1 via an insulation film 4 by two steps: e.g. first phosphorus ion implantation, and next arsenic ion implantation. Said impurities are diffused by heat treatment, and the first semiconductor region 7 and the second semiconductor region 8 are formed. Since the source region and the drain region of a MISFET composed of the region 7 and the region 8 can be separated in such a manner, the sufficient effect channel length can be secured; accordingly, short channel effect can be prevented.
