METHOD OF MANUFACTURING SEMICONDUCTOR DEVICE |
摘要 |
According to one embodiment, a method of manufacturing a semiconductor device includes dry-etching a member containing silicon in a first pressure range equal to or more than a first pressure or in a second pressure range equal to or less than a second pressure, wherein the first pressure is obtained by multiplying a saturated pressure by 0.85, the saturated pressure is defined as a pressure under which an etching rate is one of a maximum value or a value obtained by multiplying the maximum value by a predetermined coefficient, and the etching rate is a half value of the maximum value under the second pressure. |
