Publication number: 20230306458Abstract: According to one embodiment, a server device for a retail stamp card service includes a communication interface connectable to a network and a storage unit for storing electronic stamp cards for a plurality of purchasers and stamp issuance conditions for a plurality of stores. A processor of the server device is configured to acquire purchaser identification information and receipt data indicating details of a purchase by a purchaser at a store and determine, based on the receipt data, whether a stamp issuance condition has been satisfied. The processor then issues stamp data if the stamp issuance condition has been satisfied and updates stamp card data according to the issued stamp data. The stamp issuance conditions can be set on an individual store basis, a brand basis, or an operating company basis based on operator input to the server device.Type: ApplicationFiled: February 21, 2023Publication date: September 28, 2023Inventors: Kento YAMADA, Takuji SAKAGUCHI

Publication number: 20230154748Abstract: A method for manufacturing a semiconductor substrate by forming an insulator film and a semiconductor single crystal layer on a surface of a silicon single crystal substrate to manufacture a semiconductor substrate having the semiconductor single crystal layer on the insulator film, the method including at least the steps of: forming a silicon nitride film having an epitaxial relationship with the silicon single crystal substrate on the surface of the silicon single crystal substrate as the insulator film by subjecting the silicon single crystal substrate to a heat treatment under a nitrogen gas-containing atmosphere; and forming the semiconductor single crystal layer on the silicon nitride film by epitaxial growth. This makes it possible to obtain a semiconductor substrate by simple method with high productivity at low cost even when the insulator film provided between the silicon single crystal substrate and the semiconductor single crystal layer is a silicon nitride film.Type: ApplicationFiled: October 8, 2020Publication date: May 18, 2023Applicant: SHIN-ETSU HANDOTAI CO., LTD.Inventors: Miho NIITANI, Taishi WAKABAYASHI, Kento YAMADA, Kazuhiko YOSHIDA
