1. An integrated circuit, comprising:
an active region in a semiconductor substrate; at least one operational device on the active region, wherein the operational device includes a strained channel; a first dummy gate disposed at a side of the operational device and directly on the active region; a dummy active region in the semiconductor substrate and adjacent the active region; a shallow trench isolation (STI) interposed between the active region and the dummy active region; and a second dummy gate disposed on the dummy active region. |
