Patent number: 6666943Abstract: A device is formed by transferring a film onto a substrate when the film requires but the substrate is not adapted to a high temperature heat treatment process. The film having layers and formed on a first substrate having layers is transferred onto a second substrate having layers. The method of transferring the film comprises a first step of forming a lift-off layer and the film to be transferred on the first substrate, a second step of bonding the film to be transferred to the second substrate and a third step of separating the film to be transferred from the first substrate by etching the lift-off layer and transferring it onto the second substrate.Type: GrantFiled: December 3, 2001Date of Patent: December 23, 2003Assignee: Canon Kabushiki KaishaInventors: Takatsugu Wada, Hidetoshi Nojiri, Masatake Akaike, Takehiko Kawasaki, Rei Kurashima, Satoshi Nozu, Kozo Hokayama
