Patent number: 9893190Abstract: A fin field effect transistor (fin FET) is formed using a bulk silicon substrate and sufficiently guarantees a top channel length formed under a gate, by forming a recess having a predetermined depth in a fin active region and then by forming the gate in an upper part of the recess. A device isolation film is formed to define a non-active region and a fin active region in a predetermined region of the substrate. In a portion of the device isolation film a first recess is formed, and in a portion of the fin active region a second recess having a depth shallower than the first recess is formed. A gate insulation layer is formed within the second recess, and a gate is formed in an upper part of the second recess. A source/drain region is formed in the fin active region of both sides of a gate electrode.Type: GrantFiled: April 24, 2017Date of Patent: February 13, 2018Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Keun-Nam Kim, Hung-Mo Yang, Choong-Ho Lee

Patent number: 7494895Abstract: A method of fabricating a 3D field effect transistor employing a hard mask spacer includes forming a hard mask pattern on a semiconductor substrate. The semiconductor substrate is etched using the hard mask pattern as an etch mask to form a trench that defines an active region. A trench oxide layer and a liner are sequentially formed on the semiconductor substrate, and an isolation layer is formed to fill the trench. An upper surface of the isolation layer may by recessed below an upper surface of the hard mask pattern. A hard mask spacer is formed that covers sidewalls of the hard mask pattern. Some portions of the isolation layer where an etching is blocked by the hard mask spacer remain on sidewalls of the channel region, respectively, thereby preventing the liner from being damaged by etching.Type: GrantFiled: March 21, 2005Date of Patent: February 24, 2009Assignee: Samsung Electronics Co., Ltd.Inventors: Hung-Mo Yang, Keun-Nam Kim
