Manufacturing method of semiconductor device |
| abstract |
When an opening diameter of a top end of a substantially column-shaped contact hole is S1, an opening diameter of a top end of a substantially column-shaped contact hole is T1, and a thickness of a silicon insulating layer is h, then contact holes are formed so as to satisfy the following conditional expression 1. T1/h < tan θ 1 < S1/h (expression 1). With this formation method, a manufacturing method of a semiconductor device can be provided which does not need covering processing using a photolithography technique when impurity regions of different conductivity types are formed using contact holes. |
