1. A semiconductor thin film comprising:
an insulating base; and
a single crystal thin film having micro-projections formed on said insulating base by heat treating a polycrystalline thin
film formed by heat treating an amorphous semiconductor thin film, said polycrystalline thin film having polycrystalline grains
aligned in a generally regular pattern forming initial micro-projections by uplift of a boundary portion among at least three
of said polycrystalline grains, at least a portion of said micro-projections of said single crystal thin film being comprised
of the initial micro-projections.
