ABSTRACT:
A method of forming a film having enhanced reflow characteristics at low thermal budget is disclosed, in which a surface layer of material is formed above a base layer of material, the surface layer having a lower melting point than the base layer. In this way, a composite film having two layers is created. After reflow, the surface layer can be removed using conventional methods.
