CAPPING LAYER FOR RECRYSTALLIZATION PROCESS

摘要

An improved method for crystallizing amorphous or polycrystalline material is disclosed, which method employs a novel intermediate product. A film of material to be crystallized is formed on a substrate. A porous silica cap is formed over the film. The resultant intermediate product is heated to melt the film which crystallizes upon cooling. Gases generated during melting of the film escape through the porous cap which also functions to prevent deleterious agglomeration of the material while it is in a molten state.
