  • Patent number: 11737276
    Abstract: A method of manufacturing a semiconductor device according to the present disclosure includes forming a stack by alternately stacking insulating films and sacrificial films on a substrate; forming, in the stack, a through-hole extending in a thickness direction of the stack; forming a block insulating film, a charge trapping film, a tunnel insulating film, and a channel film on an inner surface of the through-hole in this order; forming, in the stack, a slit extending in the thickness direction of the stack separately from the through-hole; removing the sacrificial films through the slit so as to form a recess between adjacent insulating films; forming a first metal oxide film on an inner surface of the recess; forming, on the first metal oxide film, a second metal oxide film having a crystallization temperature lower than that of the first metal oxide film; and filling the recess with an electrode layer.

  • Publication number: 20200130300
    Abstract: A coating method includes a) supplying a coating liquid including a resin to a lens surface of a lens body made of a resin, the lens surface being on one side of the lens body, and b) forming a film of the coating liquid on the lens surface by rotating the lens body around a predetermined rotational axis. The film of the coating liquid is a buffer layer provided between the lens body and an anti-reflection layer. When the lens surface is a convex surface, the viscosity of the coating liquid is about 8 mPa·s or more and about 26 mPa·s or less and a number of revolutions of the lens body in the step b) is about 4500 rpm or more and about 30000 rpm or less.

  • Patent number: 9551068
    Abstract: A film forming method includes supplying a first source gas containing a first metal element onto a substrate, supplying a second source gas containing a second metal element onto the substrate, supplying a reaction gas converted into plasma and containing a nonmetal element reacting with the first metal element and the second metal element to generate a first reaction product and a second reaction product, respectively, to the substrate, to generate a third reaction product containing the first metal element, the second metal element and the nonmetal element. A mixing ratio of the first metal element contained in the third reaction product is higher than that of the second metal element, and a crystallization temperature of the second reaction product is higher than that of the first reaction product.

  • Publication number: 20150184294
    Abstract: A film deposition apparatus rotates a turntable and each gas nozzle relatively to each other at a rotational speed of 100 rpm or higher when depositing a titanium nitride film, to speed up a reaction gas supply cycle or a film deposition cycle of a reaction product.
