Abstract:
An exposure mask for forming a G-type active region with a double patterning technology includes a bar shaped first light-blocking pattern to define an I-type active region, and an island shaped second light-blocking pattern to define a bit line contact region. The first light-blocking pattern and the second light-blocking pattern are arranged alternately.
