    摘要: A semiconductor device with improved transistor operating and flicker noise characteristics includes a substrate, an analog NMOS transistor and a compressively-strained-channel analog PMOS transistor disposed on the substrate. The device also includes a first etch stop liner (ESL) and a second ESL which respectively cover the NMOS transistor and the PMOS transistor. The relative measurement of flicker noise power of the NMOS and PMOS transistors to flicker noise power of reference unstrained-channel analog NMOS and PMOS transistors at a frequency of 500 Hz is less than 1.

    摘要: In a method of fabricating a CMOS transistor, and a CMOS transistor fabricated according to the method, the characteristics of first and second conductivity type MOS transistors are both simultaneously improved. At the same time, the fabrication process is simplified by reducing the number of masks required. The method includes amorphizing the active region of only the second conductivity type MOS transistor, and performing selective etching to form a first recessed region of a first depth in the active region of the first conductivity type MOS transistor and a second recessed region of a second depth that is greater than the first depth in the active region of the second conductivity type MOS transistor. Selective epitaxial growth is performed in the first and second recessed regions to form an elevated epitaxial layer that fills the first recessed region and extends to a level that is above the upper surface of the semiconductor substrate and to form a recessed epitaxial layer that fills the second recessed region.

    摘要: A semiconductor device includes a substrate having a semiconductor channel region therein. A gate electrode is provided on the channel region. A SiGeC stress-inducing region is provided adjacent the channel region. The SiGeC region is configured to form a semiconductor junction with the channel region and induce a net mobility-enhancing stress in a portion of the channel region. The SiGeC region may have a Ge/C atomic ratio of less than about 12. The SiGeC region also has a sufficient concentration of substitutional C atoms therein to induce a net tensile stress in the portion of the channel region, which has a different lattice constant relative to the SiGeC region.
