Abstract
The method of the invention induces crystallization in an amorphous semiconductor layer, and includes the steps of: a) producing a patterned metal layer on a first substrate, the metal layer exhibiting a weak level of adherence to the first substrate; b) pressing the metal layer into physical contact with the amorphous semiconductor layer; c) applying heat, light or both to the metal layer and amorphous semiconductor layer to cause a reaction therebetween and a crystallization of the amorphous semiconductor that is juxtaposed to the metal.
