    摘要: A semiconductor device includes a semiconductor layer of a first conductivity type and a first doping concentration. A first semiconductor region, used as drain, of the first conductivity type has a lower doping concentration than the semiconductor layer and is over the semiconductor layer. A gate dielectric is over the first semiconductor region. A gate electrode over the gate dielectric has a metal-containing center portion and first and second silicon portions on opposite sides of the center portion. A second semiconductor region, used as a channel, of the second conductivity type has a first portion under the first silicon portion and the gate dielectric. A third semiconductor region, used as a source, of the first conductivity type is laterally adjacent to the first portion of the second semiconductor region. The metal-containing center portion, replacing silicon, increases the source to drain breakdown voltage.

    摘要: A method of forming a metal oxide semiconductor (MOS) device comprises defining an active area in an unstrained semiconductor layer structure, depositing a hard mask overlying the active area and a region outside of the active area, patterning the hard mask to expose the active area, selectively growing a strained semiconductor layer overlying the exposed active area, and forming a remainder of the MOS device. The active area includes a first doped region of first conductivity type and a second doped region of second conductivity type. The strained semiconductor layer provides a biaxially strained channel for the MOS device. During a portion of forming the remainder of the MOS device, dopant of the first conductivity type of the first doped region of the active area and dopant of the second conductivity type of the second doped region of the active area diffuses into overlying portions of the strained semiconductor layer to create a correspondingly doped strained semiconductor layer, thereby providing corresponding doping for the biaxially strained channel.
