Abstract
A semiconductor device includes a local oxidation of silicon (LOCOS) structure and a shallow trench isolation (STI) structure formed over a semiconductor substrate. A source region is located between the LOCOS structure and the STI structure. A gate structure is located between the source region and the LOCOS structure. A contact may be located over the STI structure electrically connect to the gate structure.
