Abstract

A manufacturing method of a thin film apparatus, includes: a first step for forming a separation layer on a heat resistant substrate; a second step for forming a thin film device on the separation layer; a third step for providing a surface layer on the thin film device; and a fourth step for generating a peeling phenomenon at the interface of the separation layer and the heat resistant substrate so as to peel the heat resistant substrate from a side of the thin film device.
