ABSTRACT:
A method for forming a semiconductor material involves forming an i-type non-single crystalline layer on a substrate and crystallizing the semiconductor material by irradiation with a light having a wavelength in the range of 250 to 600 nm. Desirably, the crystals of the semiconductor material extend in column form approximately perpendicular to the substrate. Preferably, the i-type layer is doped with a recombination center neutralizer selected from hydrogen and a halogen element and the concentration of impurities forming recombination centers, such as oxygen, nitrogen, carbon, phosphorus and boron, are maintained at 1 atomic % or less.
