Patent number: 8404498Abstract: A method of forming a semiconductor thin film includes: a step of forming an amorphous semiconductor thin film over a transparent substrate; a step of forming a crystalline semiconductor thin film by irradiating the amorphous semiconductor thin film with laser light to provide heat treatment and thereby crystallizing the amorphous semiconductor thin film; and an inspection step of inspecting the crystalline semiconductor thin film. The inspection step includes a step of obtaining a transmission image of the crystalline semiconductor thin film by irradiating the crystalline semiconductor thin film with light from a rear side of the transparent substrate and taking an image, and a screening step of performing screening of the crystalline semiconductor thin film based on the obtained transmission image.Type: GrantFiled: August 7, 2009Date of Patent: March 26, 2013Assignee: Sony CorporationInventors: Hirohisa Amago, Nobuhiko Umezu

Publication number: 20120231559Abstract: A method of forming a semiconductor thin film includes the steps of: forming an amorphous semiconductor thin film on a substrate; forming a crystalline semiconductor thin film partially in each element region by applying laser light to the amorphous semiconductor thin film to selectively perform a heating process on the amorphous semiconductor thin film, thereby crystallizing the amorphous semiconductor thin film in a region irradiated with the laser light; and inspecting the crystallinity degree of the crystalline semiconductor thin film. The step of inspecting includes the steps of determining a contrast between the luminance of a crystallized region and the luminance of a non-crystallized region by applying light to the crystalline semiconductor thin film and the amorphous semiconductor thin film, and performing screening of the crystalline semiconductor thin film on the basis of the determined contrast.Type: ApplicationFiled: May 22, 2012Publication date: September 13, 2012Applicant: SONY CORPORATIONInventors: Nobuhiko UMEZU, Koichi TSUKIHARA, Hirohisa AMAGO, Go MATSUNOBU, Katsuya SHIRAI

Patent number: 5402314Abstract: A printed circuit board having a through-hole in a land is disclosed. A solder resist of a photo-curable solder resist is formed on the substrate surface of the printed circuit board and the through-hole is stopped with the same photo-curable solder resist as the solder resist layer. If a land on which a chip component is mounted co-exists with a land on which a discrete component is mounted, only the through-hole in the land on which the chip component is mounted is selectively stopped with the photo-curable solder resist. The solder resist layer and the photo-curable solder resist stopping the through-hole are formed by selective light exposure from both the front and reverse surfaces of the substrate.Type: GrantFiled: February 3, 1993Date of Patent: March 28, 1995Assignee: Sony CorporationInventors: Hirohisa Amago, Seimi Ishii, Nobuo Komatsu, Nobuyuki Yasuda
