Method of filling apertures with crystalline material

摘要

A sheet containing the apertures to be filled is coated with a layer of crystalline material. A localized heat source heats small portions of the layer at a time. The crystalline material in each portion is melted and allowed to flow into the apertures. The localized heat source is then moved to heat a different portion of the crystalline layer. In this fashion the layer of crystalline material is scanned with the localized heat source so that the crystalline material melts, flows into the apertures to be filled and then recrystallizes.
