Patent ID: 7923317

Claim:
A solid phase crystallization method, comprising the following successive steps: a) depositing a first layer of amorphous or polycrystalline material on a surface of a top part of a substrate, b) depositing a metal layer with a thickness in a range between 1 nm and 20 nm on the first layer, the top part of the substrate comprising, after step b), a second material in an amorphous state able to change to a liquid or an overmelted liquid state, and c) performing a thermal treatment to enable crystalline growth of the material of the first layer, simultaneously causing: a temperature increase of the top part of the substrate at a rate of more than 100K per second until the second material of the top part of the substrate goes to the liquid or the overmelted liquid state, and a heat transfer from an interface between the top part of the substrate and the first layer to an interface between the first layer and the metal layer.
