SEMICONDUCTOR DEVICE HAVING STRAIN MATERIAL

摘要

A semiconductor device having strain material is disclosed in a particular embodiment, the semiconductor device includes a first cell including a first gate between a first drain and a first source. The semiconductor device also includes a second cell adjacent to the first cell. The second cell includes a second gate between a second drain and a second source. The semiconductor device further includes a shallow trench isolation area between the first source and the second source. A first amount of strain material over the first source and over the second source is greater than a second amount of strain material over the first drain and over the second drain.
