Abstract:
An integrated circuit device includes at least two epitaxially grown active regions grown onto a substrate, the active regions being placed between a first gate device and a second gate device. The integrated circuit device includes at least one dummy gate between the two epitaxially grown active regions and between the first gate device and the second gate device, wherein each active region is substantially uniform in length. The first gate device and the second device are formed over a first well having a first conductivity type and the dummy gate is formed over a second well having a second conductivity type.
