Patent number: 9136182Abstract: 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.Type: GrantFiled: May 16, 2014Date of Patent: September 15, 2015Assignee: SEMICONDUCTOR MANUFACTURING INTERNATIONAL (SHANGHAI) CORPORATIONInventors: Qingsong Wei, Shukun Yu
