Patent number: 7459379Abstract: When a semiconductor film is irradiated with laser light, the semiconductor film is instantaneously melted and expand locally. In order to reduce internal stress generated by this expansion, strain is locally generated in the semiconductor film. Accordingly, a variation is caused among portions with strain and portions without strain, and a variation is caused also by a difference in extent of strain. According to the present invention, after laser light irradiation, an oxide film (referred to as a chemical oxide) is formed by using a solution containing ozone (typically, ozone water) to form an oxide film of 1 to 10 nm in total, and further, a heat treatment for reducing strain of a semiconductor film (a heat treatment of heating the semiconductor film instantaneously to approximately 400 to 1000° C.) is performed.Type: GrantFiled: March 25, 2005Date of Patent: December 2, 2008Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Chiho Kokubo, Shunpei Yamazaki, Tamae Takano, Hiroaki Irie

Patent number: 7200102Abstract: A main information area 31 capable of recording an information signal and a subsidiary information area 32 for recording subsidiary information that is different from the information signal are divided in one principal plane direction of a substrate, and an information layer for recording the information signal in the main information area 31 is provided also in the subsidiary information area 32, and medium identification information for distinguishing the medium optically is recorded in the information layer of the subsidiary information area 32 without changing the shape of the information layer. As a result, the medium identification information can be recorded in an optical recording medium 1 stably. In particular, the initialization of a phase change type optical recording medium and the recording of the medium identification information can be performed at the same time, so that the production process can be simplified, and the production costs can be reduced.Type: GrantFiled: March 21, 2005Date of Patent: April 3, 2007Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Hiroaki Irie, Keiichiro Horai, Kenichi Nishiuchi, Mitsuaki Oshima
