Abstract:
A semiconductor device comprising an n-channel and a p-channel field effect transistor on a substrate, wherein the n-channel field effect transistor includes:a first silicon layer formed on a substrate; a first SiGeC layer in which an n-channel is formed, and which is formed on the first silicon layer, contains carbon and germanium and has received a tensile strain from the first silicon layer; and a gate electrode formed over the first SiGeC layer, the p-channel field effect transistor including: a second silicon layer formed on a substrate; a second SiGeC layer in which a p-channel is formed, and which is formed on the second silicon layer, contains carbon and germanium and has received a tensile strain from the second silicon layer; and a gate electrode formed over the second SiGeC layer, wherein the semiconductor device functions as a complementary device.
