Method for manufacturing semiconductor device |
摘要 |
Provided is a method for manufacturing a semiconductor device which includes, on a wafer which has a notch, a plurality of transistors parallel with and perpendicular to a notch direction extending between the center of the wafer and the notch, the method including: preparing the wafer having the front surface which has Off angle of at least 2 degrees and at most 2.8 degrees from plane in a direction in which Twist angle relative to the notch direction is at least 12.5 degrees and at most 32.5 degrees; and doping impurities into the front surface of the wafer in a direction perpendicular to the front surface. |

1. A method for manufacturing a semiconductor device which includes, on a semiconductor substrate having a notch, a plurality of transistors in parallel with and perpendicular to a notch direction extending between a center of the semiconductor substrate and the notch, the method comprising:
preparing the semiconductor substrate which has a front surface having an Off angle of at least 2 degrees and at most 2.8 degrees from (100) plane in a direction in which a Twist angle relative to the notch direction is at least 12.5 degrees and at most 32.5 degrees; and doping impurities into the front surface of the semiconductor substrate in a direction perpendicular to the front surface. |
