Abstract
Disclosed herein is an apparatus that includes: a semiconductor substrate including first and second STI regions arranged in a first direction, a first diffusion region having a first conductivity type surrounded by the first STI region, a second diffusion region having a second conductivity type surrounded by the second STI region, and a third diffusion region extending in a second direction such that the third diffusion region is arranged between the first and second STI regions; a first gate electrode including a first polycrystalline silicon film covering a part of the first diffusion region to form a P-channel MOS transistor; a second gate electrode including a second polycrystalline silicon film covering a part of the second diffusion region to form an N-channel MOS transistor; and a third polycrystalline silicon film extending in the second direction such that the third polycrystalline silicon film covers the third diffusion region.
