Abstract

Abstract Translated from Japanese (57)【要約】 【課題】SOI構造による効果を失わずに、高品質で十 分な歪みを有する歪みシリコン層を形成できる構造のM OSFETを提供すること。 【解決手段】埋め込み絶縁層3が挿設され、この埋め込 み絶縁層3により上下に区分された歪み印加半導体層と してのSiGe層2と、上側のSiGe層2上に形成さ れたチャネル層としての歪みシリコン層4とを備え、埋 め込み絶縁層3は上側のSiGe層2の膜厚が薄くなる ように形成され、かつ歪みシリコン層4の形成前に、S iGe層2および埋め込み絶縁層3の形成時にSiGe 層2内に発生した転位等の欠陥を低減するための熱処理 がSiGe層2に施されている。 (57) Abstract: An M structure having a structure capable of forming a strained silicon layer having high quality and sufficient strain without losing the effect of the SOI structure. Providing OSFET. A buried insulating layer (3) is inserted, and a SiGe layer (2) as a strain applying semiconductor layer divided into upper and lower parts by the buried insulating layer (3) and a strain as a channel layer formed on the upper SiGe layer (2). The buried insulating layer 3 is formed so that the film thickness of the upper SiGe layer 2 is thin, and before the formation of the strained silicon layer 4, S When forming the iGe layer 2 and the buried insulating layer 3, SiGe A heat treatment for reducing defects such as dislocations generated in the layer 2 is applied to the SiGe layer 2.
