Abstract:
1. A method for producing a thin film, comprising steps of: providing a primary substrate; forming an etching stop layer on the primary substrate; forming at least one sacrificial layer on the etching stop layer; implanting gas ions with an ion implantation technique, so that the gas ions are implanted through the sacrificial layer and then through the etching stop layer, so that an ion implantation peak layer is formed in the primary substrate, thereby defining an effective transferred layer and a remnant layer, with a thickness of the effective transferred layer determined by a thickness of the sacrificial layer and an ion implantation energy used in the ion implantation technique; removing the sacrificial layer with one of an etching treatment, a chemical solution etching treatment, and an ion plasma etching treatment; and separating the effective transferred layer from the remnant layer by applying an energy input treatment to polymerize the implanted gas ions.
