Title:
半導体装置の作製方法
Document Type and Number:
Japanese Patent JP6983569
Kind Code:
B2
Abstract:
To increase the yield of the separation process. To produce display devices formed through the separation process with higher mass productivity. A first layer is formed using a material including a resin or a resin precursor over a substrate. Then, first heat treatment is performed on the first layer, whereby a first resin layer including a residue of an oxydiphthalic acid is formed. Then, a layer to be separated is formed over the first resin layer. Then, the layer to be separated and the substrate are separated from each other.
