Abstract

A semiconductor device includes a common diffusion structure formed in each region of a substrate in which semiconductor components are formed. The diffusion structures are separated into sections by trenches to form semiconductor components. The trenches define sizes of the semiconductor components and isolate the semiconductor components from the surrounding area.
