Description
図17及び18は、本発明の他の一実施形態に従った傾斜された底部バリア領域406及びスペーサ領域410を例示するグラフである。図17は、底部バリア領域406の組成をその底面456と頂面458との間について例示するグラフであり、図18は、スペーサ領域410の組成をその底面460と頂面462との間について例示するグラフである。図17にて見て取れるように、底部バリア406はその底面456でSiGeを有し、且つその厚さの一部にわたって同じ組成のままである。そして、底部バリア406の厚さの途中で、Siが減少し始め且つGeが増加し、頂面458で底部バリア406は選択された組成を有する。この実施形態において、頂面458における選択された組成は、チャネル領域408の組成と同じではない。図18は、スペーサ領域410に関してこの逆のことを示しており、スペーサ領域410は底面460で、チャネル領域408の組成とは幾分異なる第1の組成を有し、スペーサ領域410の組成は、スペーサ領域410が選択された組成に達するまで、頂面462に向かって、チャネル領域408の組成とは似ないものとなっていき、そして、頂面462までこの選択された組成であり続ける。
