摘要:
A method of making a semiconductor device comprises: providing a semiconductor wafer having a semiconductor layer; forming a first mask layer over the semiconductor layer; forming a second mask layer over the first mask layer; annealing the second mask layer to form islands; etching through the first mask layer and the semiconductor layer using the islands as a mask to form an array of pillars; and growing semiconductor material between the pillars and then over the tops of the pillars.
