Patent number: 7419858Abstract: A recessed-gate thin-film transistor (RG-TFT) with a self-aligned lightly doped drain (LDD) is provided, along with a corresponding fabrication method. The method deposits an insulator overlying a substrate and etches a trench in the insulator. The trench has a bottom and sidewalls. An active silicon (Si) layer is formed overlying the insulator and trench, with a gate oxide layer over the active Si layer. A recessed gate electrode is then formed in the trench. The TFT is doped and LDD regions are formed in the active Si layer overlying the trench sidewalls. The LDD regions have a length that extends from a top of the trench sidewall, to the trench bottom, with a doping density that decreases in response to the LDD length. Alternately stated, the LDD length is directly related to the depth of the trench.Type: GrantFiled: August 31, 2006Date of Patent: September 2, 2008Assignee: Sharp Laboratories of America, Inc.Inventors: Paul J. Schuele, Mark A. Crowder, Apostolos T. Voutsas, Hidayat Kisdarjono

Patent number: 7419859Abstract: Provided are methods for fabricating semiconductor devices incorporating a fin-FET structure that provides body-bias control, exhibits some characteristic advantages associated with SOI structures, provides increased operating current and/or reduced contact resistance. The methods for fabricating semiconductor devices include forming insulating spacers on the sidewalls of a protruding portion of a first insulation film; forming a second trench by removing exposed regions of the semiconductor substrate using the insulating spacers as an etch mask, and thus forming fins in contact with and supported by the first insulation film. After forming the fins, a third insulation film is formed to fill the second trench and support the fins. A portion of the first insulation film is then removed to open a space between the fins in which additional structures including gate dielectrics, gate electrodes and additional contact, insulating and storage node structures may be formed.Type: GrantFiled: August 17, 2006Date of Patent: September 2, 2008Assignee: Samsung Electronics, Co., Ltd.Inventors: Suk-Pil Kim, Yoon-Dong Park, Won-Joo Kim, Dong-Gun Park, Eun-Suk Cho, Suk-Kang Sung, Byung-Yong Choi, Tae-Yong Kim, Choong-Ho Lee

Patent number: 7419860Abstract: A crystalline semiconductor having an even surface and a large crystal grain size is formed on an economical glass substrate using a laser crystallizing technology. A series of processes, including forming an insulation film on a glass substrate; forming a semiconductor film in the first layer; crystallizing the semiconductor film in the first layer by irradiating laser light stepwise from weak energy laser light to strong energy laser light; forming a semiconductor film in a second layer having a film thickness thinner than that of the semiconductor film in the first layer; performing laser crystallization of the semiconductor thin film in the second layer by irradiating laser light stepwise from weak energy laser light to strong energy laser light, are continuously performed without exposing the workpiece to the atmosphere.Type: GrantFiled: March 17, 2003Date of Patent: September 2, 2008Assignee: Hitachi, Ltd.Inventors: Youmei Shinagawa, Akio Mimura, Genshiro Kawachi, Takeshi Satoh

Patent number: 7419861Abstract: To form a polycrystalline silicon film having a grain size of 1 ?m or greater by means of laser annealing. A beam emitted from a laser apparatus (101) is split in two by a half mirror. The split beams are processed into linear shapes by cylindrical lenses (102) to (105), and (207), then simultaneously irradiate an irradiation surface (209). If an amorphous silicon film formed on a glass substrate is disposed on the irradiation surface (209), an area will be irradiated by both a linear shape beam entering from a front surface and a linear shape beam that has transmitted through the glass surface. Both linear shape beams irradiate the same area to thereby crystallize the amorphous silicon film.Type: GrantFiled: June 22, 2005Date of Patent: September 2, 2008Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Koichiro Tanaka, Shunpei Yamazaki, Ritsuko Kawasaki

Patent number: 7419863Abstract: Complementary IGFETs (210W and 220W or 530 and 540) are fabricated so that the body dopant concentration in each IGFET decreases by at least 10 in moving from a subsurface location in the body material of that IGFET up to one of its source/drain zones. Semiconductor dopant, typically a fast-diffusing species such as aluminum, is introduced into starting semiconductor material to form a relatively uniformly doped region that serves as body material (108) for one of the IGFETs. A remaining part of the starting material serves as body material (268) for the other IGFET. Well dopant is introduced into the body material of each IGFET for establishing the requisite body dopant profile. Alternatively, a cavity is formed through an initial structure having body material (108) doped in the preceding way for one of the IGFETs. Semiconductor material is introduced into the cavity to form the body material (568) for the other IGFET.Type: GrantFiled: August 29, 2005Date of Patent: September 2, 2008Assignee: National Semiconductor CorporationInventor: Constantin Bulucea
