    摘要: The present invention discloses an architecture of a NMOS transistor with a compressive strained Si—Ge channel fabricated on a silicon (110) substrate, which comprises: a p-silicon (110) substrate, two n+ ion-implanted regions functioning as the source and the drain respectively, a compressive strained Si—Ge channel layer, and a gate structure. The compressive strained Si—Ge channel layer is grown on the p-silicon (110) substrate to reduce the electron conductivity effective mass in the [1_l -10] crystallographic direction and to promote the electron mobility in the [1-10] crystallographic direction. Thus, the present invention can improve the electron mobility of a NMOS transistor via the channels fabricated on the silicon (110) substrate. Further, the NMOS transistor of the present invention can combine with a high-speed PMOS transistor on a silicon (110) substrate to form a high-performance CMOS transistor on the same silicon (110) substrate.
