    摘要: A method of forming a semiconductor structure includes forming a PMOS device and an NMOS device. The step of forming the PMOS device includes forming a first gate stack on a semiconductor substrate; forming a first offset spacer on a sidewall of the first gate stack; forming a stressor in the semiconductor substrate using the first offset spacer as a mask; and epitaxially growing a first raised source/drain extension (LDD) region on the stressor. The step of forming the NMOS device includes forming a second gate stack on the semiconductor substrate; forming a second offset spacer on a sidewall of the second gate stack; epitaxially growing a second raised LDD region on the semiconductor substrate using the second offset spacer as a mask; and forming a deep source/drain region adjoining the second raised LDD region.

    摘要: A semiconductor structure includes a semiconductor substrate comprising a PMOS region and an NMOS region; a PMOS device in the PMOS region; and an NMOS device in the NMOS region. The PMOS device includes a first gate stack on the semiconductor substrate; a first offset spacer on a sidewall of the first gate stack; a stressor in the semiconductor substrate and adjacent to the first offset spacer; and a first raised source/drain extension region on the stressor and adjoining the first offset spacer, wherein the first raised source/drain extension region has a higher p-type dopant concentration than the stressor. The NMOS device in the NMOS region includes a second gate stack on the semiconductor substrate; a second offset spacer on a sidewall of the second gate stack; a second raised source/drain extension region on the semiconductor substrate and adjoining the second offset spacer; and a deep source/drain region adjoining the second raised source/drain extension region, wherein the deep source/drain region is free from stressors formed in the semiconductor substrate.

    摘要: A semiconductor device includes a semiconductor substrate, a gate stack overlying the semiconductor substrate, a spacer on a sidewall of the gate stack, a lightly doped source/drain (LDD) region adjacent the gate stack, a deep source/drain region adjoining the LDD region, and a graded silicide region on the deep source/drain region and the LDD region. The graded silicide region includes a first portion having a first thickness and a second portion adjoining the first portion and having a second thickness substantially less than the first thickness. The second portion is closer to a channel region than the first portion.
