Abstract

PURPOSE:To reduce noises and to make the size small by separating a memory circuit and other elements by providing an insulating layer to the depth of 1mum or more from the surface of a substrate. CONSTITUTION:Regions 1 and 2 are formed on a same substrate 9. A memory cell 3 is formed on the region 1; and a gate 4, a source 5, and a drain 6 are formed on the region 2. An insulating layer 7 is formed by ion implantation and the like so that it reaches the point sufficiently deep from the surface, thereby minority carriers which are generated in the substrate 9 and are capable of moving in the substrate 9 are prevented from moving into the region 1. In this constitution, noises are eliminated, holding characteristics can be enhanced accordingly, and the size can be reduced.
