Patent ID: 7879689

Claim:
A method for manufacturing a semiconductor device, comprising the steps of: preparing a plurality of first semiconductor substrates, wherein a side surface of each of the first semiconductor substrates has a first crystal plane direction; preparing a plurality of second semiconductor substrates, wherein a side surface of each of the second semiconductor substrates has a second crystal plane direction, which is different from the first crystal plane direction; forming a semiconductor ingot by bonding each of the first semiconductor substrates and each of the second semiconductor substrates alternately, wherein an upper surface of the semiconductor ingot comprises the side surfaces of the first semiconductor substrates having the first crystal plane direction and the side surfaces of the second semiconductor substrates having the second crystal plane direction alternately arranged in stripe; forming a third semiconductor substrate in which portions of the first semiconductor substrates and portions of the second semiconductor substrates are alternately arranged in stripe by slicing the semiconductor ingot parallel to the upper surface.
