Patent ID: 7868386

Claim:
A semiconductor device comprising: a gate electrode formed over a gate oxide overlying a semiconductor substrate active area, the gate electrode having sidewalls, the active area beneath the gate oxide defining a channel region for the semiconductor device; lightly doped source/drain diffusions formed into the semiconductor substrate adjacent the sidewalls of the gate electrodes and having a concentration of dopant atoms of a first type, the lightly doped source/drain diffusions having an inner boundary that extends beneath the gate electrode; recesses formed in the lightly doped source/drain diffusions adjacent the sidewalls such that the gate oxide is located above the surface of the recessed lightly doped source/drain diffusions; composite sidewall insulators formed on the sidewalls of the gate electrodes and overlying the recesses; source/drain diffusions formed into the semiconductor substrate adjacent the outer edge of the composite sidewall insulators and in physical contact with the lightly doped source/drain diffusions; and pocket source/drain diffusions formed beneath the recesses and at the boundary of the source/drain diffusions and the channel region of the semiconductor substrate.
