PEELING METHOD AND PEELING APPARATUS

摘要

An object is to provide a novel peeling method and a novel peeling apparatus. A peeling method including a first step of forming a separation layer over a substrate, a second step of forming a layer to be separated over the separation layer, a third step of forming a peeling starting point by separating part of the layer to be separated from the separation layer, and a fourth step of peeling the layer to be separated from the substrate using the peeling starting point. In the fourth step, the substrate temperature is higher than or equal to 60 degrees Celsius and lower than or equal to 90 degrees Celsius.
