Patent abstract
In a semiconductor device including multiple unit cells arranged in an array, transistors are affected by a stress from an STI at different degrees depending on the position in the array. As a result, a variation occurs in transistor characteristic. In a semiconductor device according to the present invention, each of predetermined transistors in outermost unit blocks in the array has a transistor size according to the stress from the STI.
