ARTICLE AND METHOD FOR FORMING LARGE GRAIN POLYCRYSTALLINE SILICON FILMS

摘要

A templated mold comprises a mold body formed from a mold material. The mold body has at least one major surface with a patterned layer formed from a patterning material disposed over the major surface. The patterned layer defines a high nucleation energy barrier surface and a plurality of nucleation surfaces, such that a contact angle of a molten semiconducting material with the nucleation surfaces is less than a contact angle of the molten semiconducting material with the high nucleation energy barrier surface, and the nucleation surfaces are formed from either the mold material or the patterning material.
