Semiconductor integrated circuit device

摘要

In a semiconductor integrated circuit device, semiconductor elements formed in active regions included in a first element formation portion (stress transition region) in a peripheral circuit formation portion are not electrically driven, while only semiconductor elements of a second element formation portion (steady stress region) are electrically driven. Therefore, the second element formation portion in the peripheral circuit formation portion is located away from an outer STI region so as to be hardly affected by compressive stress.
