  • Patent number: 9425311
    Abstract: A method is provided for fabricating MOS transistors. The method includes providing a semiconductor substrate having at least a first region and a second region; and forming first transistors on the semiconductor substrate. Wherein source/drain regions of the first transistors are configured as SiGe growth regions; and a first density of SiGe growth regions in the first region is smaller than a second density of SiGe growth regions in the second region.

  • Patent number: 9136182
    Abstract: A method for manufacturing a semiconductor device may include forming a gate structure that includes a dummy gate member on a substrate. The method may further include forming two first-type spacers such that the dummy gate member is positioned between the first-type spacers. The method may further include forming two second-type spacers such that the first-type spacers are positioned between the second-type spacers. The method may further include forming two third-type spacers such that the second-type spacers are positioned between the third-type spacers. The method may further include performing etch to remove the third-type spacers and to at least partially remove the second-type spacers. The method may further include removing at least a portion of the dummy gate member to form a space between remaining portions of the first-type spacers. The method may further include providing a metal material in the space for forming a metal gate member.
