Patent ID: 8446176

Claim:
A configured base cell module comprising: a plurality of base cells, each having a fixed circuit structure through a second metal (M 2 ) layer and comprising: an n-well and a p-well formed in a substrate, PMOS and NMOS gate electrode structures formed over the n-well and p-well and electrically separated from another up to the second metal (M 2 ) layer, P+ implant and N+ implant regions formed adjacent to the PMOS and NMOS gate electrode structures in the n-well and p-well, respectively, and first and second power supply lines formed over the n-well and p-well and electrically separated from another up to the second metal (M 2 ) layer; and one or more conductor elements formed over a first base cell above the M 2 layer to configure the first base cell to provide a predetermined circuit function.
