Patent number: 8759200Abstract: The present invention discloses that under modified chemical vapor deposition (mCVD) conditions an epitaxial silicon film may be formed by exposing a substrate contained within a chamber to a relatively high carrier gas flow rate in combination with a relatively low silicon precursor flow rate at a temperature of less than about 550° C. and a pressure in the range of about 10 mTorr-200 Torr. Furthermore, the crystalline Si may be in situ doped to contain relatively high levels of substitutional carbon by carrying out the deposition at a relatively high flow rate using tetrasilane as a silicon source and a carbon-containing gas such as dodecalmethylcyclohexasilane or tetramethyldisilane under modified CVD conditions.Type: GrantFiled: June 23, 2011Date of Patent: June 24, 2014Assignees: Matheson Tri-Gas, Inc., International Business Machines CorporationInventors: Terry Arthur Francis, Satoshi Hasaka, Paul David Brabant, Robert Torres, Jr., Hong He, Alexander Reznicek, Thomas N.

Publication number: 20080128833Abstract: A high-dielectric-constant film including hafnium, wherein the above-mentioned high-dielectric-constant film includes deuterium at a ratio higher than the ratio of deuterium to hydrogen present in nature. In a field-effect transistor provided with the high-dielectric-constant film including hafnium, the interface state density at the interface between a silicon substrate and a gate dielectric film decreases and carrier mobility in the gate dielectric film increases. In the present invention, a high-dielectric-constant constant second dielectric film, which is a thin film including hafnium such as HfSiON or HfAlOx and including deuterium at a ratio higher than the ratio of deuterium to hydrogen present in nature, is used as the gate dielectric film of the field-effect transistor.Type: ApplicationFiled: August 25, 2005Publication date: June 5, 2008Inventors: Takaaki Kawahara, Kazuyoshi Torii, Minoru Inoue, Satoshi Hasaka

Patent number: 6910602Abstract: A container valve, attached to a gas container, wherein the container valve has a pressure reducing function, and is inside a valve block in the gas container. In the valve block, the container valve comprises a gas filling passage in which a filling valve is installed, a gas lead-out passage in which a lead-out valve is installed, and a pressure regulator arranged at an upstream side of the lead-out valve in the gas lead-out passage. The container valve can safely supply gas under a reduced pressure for use by opening the container valve of a container whose pressure is high and gas can be filled easily into the container. The container valve can be miniaturized and the purging operation for supplying high purity gas can be performed.Type: GrantFiled: November 26, 2002Date of Patent: June 28, 2005Assignees: Taiyo Nippon Sanso Corporation, Hamai Industries LimitedInventors: Satoshi Hasaka, Yutaka Horiuchi, Masao Koizumi
