Abstract:
To improve peelability, yield in a peeling step, and yield in manufacturing a flexible device. A peeling method is employed which includes a first step of forming a peeling layer containing tungsten over a support substrate; a second step of forming, over the peeling layer, a layer to be peeled formed of a stack including a first layer containing silicon oxynitride and a second layer containing silicon nitride in this order and forming an oxide layer containing tungsten oxide between the peeling layer and the layer to be peeled; a third step of forming a compound containing tungsten and nitrogen in the oxide layer by heat treatment; and a fourth step of peeling the peeling layer from the layer to be peeled at the oxide layer.

Claim (Index 3):
The peeling method according to  claim 1 ,\n wherein in the second step, the first layer comprising a region comprising nitrogen and a region comprising hydrogen is formed, wherein a nitrogen content in the region comprising nitrogen measured by secondary ion mass spectrometry is greater than or equal to 5.0\u00d710 20  molecules/cm 3  and less than or equal to 1.0\u00d710 23  molecules/cm 3 , and wherein a hydrogen content in the region comprising hydrogen is greater than or equal to 1.0\u00d710 20  molecules/cm 3  and less than or equal to 1.0\u00d710 22  molecules/cm 3 .
