  • Patent number: 6740550
    Abstract: A semiconductor device having a chamfered silicide layer and a manufacturing method of the same. The semiconductor device includes: a first insulation layer overlying a semiconductor substrate; gate structures including first conductive layer patterns formed on the first insulation layer, and second conductive layer patterns which are formed on the first conductive layer patterns, wherein the lower sides of the second conductive layer patterns are substantially perpendicular to the major surface of the semiconductor substrate and the upper sides of the second conductive layer patterns are chamfered; and a second insulation layer formed with a first width W on the second conductive layer patterns, wherein the sidewalls of the second insulation layer overhang the upper edges of the second conductive layer patterns.
    Type: Grant
    Filed: July 3, 2002
    Date of Patent: May 25, 2004
    Assignee: Samsung Electronics Co., Ltd.
    Inventors: Chang-won Choi, Dae-hyuk Chung, Woo-sik Kim, Shin-woo Nam, Yeo-cheol Yoon, Bum-su Kim, Jong-ho Park, Ji-hwan Choi
