    • The invention provides a transistor, including: a substrate having a channel region; a source region and a drain region on two ends of the channel region of the substrate respectively; a gate high-K dielectric layer on a top surface of the substrate above the channel region between the source region and the drain region; an interfacial layer under the gate high-K dielectric layer, including a first portion near the source region and a second portion near the drain region, wherein an equivalent oxide thickness of the first portion is larger than that of the second portion. An asymmetric replacement metal gate forms an asymmetric interfacial layer, which is thin at the drain region side and thick at the source region side. At the thin drain region side, the short channel effect is significant and the asymmetric interfacial layer advantageously suppresses the short channel effect. At the thick source region side, the carrier mobility has a large influence on the device, and the asymmetric interfacial layer prevents the carrier mobility from decreasing. Further, the asymmetric replacement metal gate implements an asymmetric metal work function.

    • The devices are manufactured by replacement gate process and replacement sidewall spacer process, and both tensile stress in the channel region of NMOS device and compressive stress in the channel region of PMOS device are increased by forming a first stress layer with compressive stress in the space within the first metal gate layer of NMOS and a second stress layer with tensile stress in the space within the second metal gate layer of PMOS, respectively. After formation of the stress layers, sidewall spacers of the gate stacks of PMOS and NMOS devices are removed so as to release stress in the channel regions. In particular, stress structure with opposite stress may be formed on sidewalls of the gate stacks of the NMOS device and PMOS device and on a portion of the source region and the drain region, in order to further increase both tensile stress of the NMOS device and compressive stress of the PMOS device.
