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 4):
The peeling method according to  claim 1 ,\n wherein in the second step, the first layer from which nitrogen and hydrogen are released is formed, wherein an amount of the released nitrogen is greater than or equal to 5\u00d710 17  molecules/cm 3  when converted into nitrogen molecules, at temperatures ranging from 100\u00b0 C. to 450\u00b0 C. in a spectrum obtained by thermal desorption spectrometry at a mass-to-charge ratio of 28, and wherein an amount of the released hydrogen is greater than or equal to 5\u00d710 19  molecules/cm 3  when converted into hydrogen molecules, at temperatures ranging from 100\u00b0 C. to 450\u00b0 C. in a spectrum at a mass-to-charge ratio of 2.
