  • Publication number: 20180019114
    Abstract: A method for depositing a silicon nitride film is provided. A nitrided adsorption site is formed in a recess formed in a surface of a substrate by supplying an ammonia-containing gas to the substrate for nitriding the surface of the substrate including the recess. A non-adsorption site is formed in a predetermined upper area of the recess by adsorbing a chlorine-containing gas on the nitride adsorption site in the predetermined upper area by physical adsorption. The predetermined upper area ranges from an upper end of the recess to a predetermined depth of the recess. A silicon-containing gas is adsorbed on the nitride adsorption site other than the predetermined upper area so as to deposit a silicon nitride film by a chemical reaction between the adsorbed ammonia-containing gas and the adsorbed silicon-containing gas. The nitride adsorption site includes a bottom surface of the recess.

  • Publication number: 20170314454
    Abstract: A vehicle includes a radiator, a bypass passage, a first valve, a second valve, and a controller. Cooling water is circulated through the radiator independently of a cylinder block and a cylinder head of an engine. The radiator cools the cooling water. The cooling water is circulated through the bypass passage while bypassing the radiator. The first valve switches between an open state in which cooling water is circulated through the cylinder block and a closed state in which cooling water is not circulated through the cylinder block. The second valve receives cooling water circulated through the cylinder head and cooling water circulated through the cylinder block via the first valve. The second valve uses an intermediate opening to adjust a flow rate of cooling water circulated through the radiator and the bypass passage. The controller controls opening and closing of the first valve and the opening of the second valve.

  • Publication number: 20170282245
    Abstract: In a three-dimensional modeling apparatus, diffusion of fumes generated around the modeling stage accompanying irradiation with an energy beam can be efficiently prevented. Three-dimensional modeling is performed by repeating scanning a modeling material arranged on a modeling stage with laser light to form a solidified layer. A cover is provided that locally surrounds an irradiation portion on the modeling material arranged on the modeling stage irradiated with the laser light, and suppresses diffusion of the fumes caused by irradiation with the laser light. In the cover, a stream of gas containing the fumes is regulated so as to cause the fumes to flow toward an upward portion inside the cover apart from the irradiated portion irradiated with the laser light.
