Publication number: 20160237566Abstract: When a film is formed atomic layer by atomic layer with a use of a raw material gas and a reaction gas, a raw material gas is supplied into a film-forming space in which a substrate is placed to adsorb a component of the raw material gas onto the substrate. Then, a reaction gas is supplied into the film-forming space. Plasma is produced in the film-forming space using the reaction gas supplied so that part of a component of the raw material gas adsorbed on the substrate reacts with the reaction gas. At this moment, a duration of production of the plasma is set within a range of 0.5 millisecond to 100 milliseconds according to a degree of at least one property of a film to be formed, and a density of power input to the plasma source is in a range of 0.05 W/cm2 to 10 W/cm2.Type: ApplicationFiled: March 13, 2014Publication date: August 18, 2016Inventors: Nozomu HATTORI, Naomasa MIYATAKE, Yasunari MORI, Yoshiharu NAKASHIMA

Patent number: 8440268Abstract: Oxygen gas, for example, is introduced into a film forming chamber, and high-frequency power is supplied to a plurality of monopole antennas arranged above a silicon substrate (101) in the film forming chamber to generate a plasma of the introduced oxygen gas, thereby supplying atomic oxygen (123) onto the surface of an aminosilane molecular layer (102). This plasma generation is performed for about 1 sec. With this operation, the adsorption layer (102) adsorbed onto the surface of the silicon substrate (101) is oxidized, thereby forming a silicon oxide layer (112) corresponding to one atomic layer of silicon on the surface of the silicon substrate (101).Type: GrantFiled: March 28, 2007Date of Patent: May 14, 2013Assignee: Mitsui Engineering & Shipbuilding Co., Ltd.Inventors: Keisuki Washio, Kazutoshi Murata, Naomasa Miyatake, Hiroyuki Tachibana, Nozomu Hattori

Patent number: 7022545Abstract: The present invention has its object to obtain an SiC monitor wafer which can flatten the surface until particle detection is possible. SiC of a crystal system 3C is deposited on a substrate by a CVD (Chemical Vapor Deposition) method, and the SiC is detached from a substrate. After the SiC surface is flattened by using mechanical polishing alone or in combination with CMP (Chemo Mechanical Polishing), GCIB (Gas Cluster Ion Beam) is irradiated to the surface until the surface roughness becomes Ra=0.5 nm or less and the impurity density of the wafer surface becomes 1*1011 atoms/cm2 or less to produce the SiC monitor wafer.Type: GrantFiled: January 10, 2003Date of Patent: April 4, 2006Assignee: Mitsui Engineering & Shipbuilding Co., Ltd.Inventors: Isao Yamada, Jiro Matsuo, Noriaki Toyoda, Kazutoshi Murata, Naomasa Miyatake
