Abstract:
1. A method of manufacturing a layered electronic device over a flexible plastic substrate, comprising: depositing a buffer layer over said flexible plastic substrate; forming a metal layer over and in physical contact with said buffer layer to thereby form a layer structure, such that said layer structure has a first lateral dimension and an induced first strain in said buffer layer; heating said layer structure to an anneal temperature which is greater than the temperature at which the plastic substrate, the buffer layer, and the metal layer plastically deform such that said layer structure is deformed to have a second lateral dimension greater than said first lateral dimension and inducing a second strain in said buffer layer greater than said first strain; cooling the layer structure such that said layer structure remains substantially at said second lateral dimension, and substantially with at least said second strain in said buffer layer; following said cooling, forming over said metal layer a layered electronic device such that:
