A Promising Planar Transistor with in-situ Doped Selective Si Epitaxy Technology (GORES MOSFET) for 32nm node and beyond

We demonstrated 40nm gate length "gate overlapped raised extension structure: GORES MOSFET" without halo implantation and prove that the ultra shallow junction (USJ) could coexist with the reducing parasitic resistance in GORES MOSFET. It is the new concept planar transistor with the gate overlapping the in-situ doped epitaxial extension to break through the trade off relation between reducing parasitic resistance and suppression of the short channel effect (SCE) (Tateshita, 2005). As a matter of course, it has the USJ and the low parasitic resistance (LPR) for 32nm node with in-situ doped selective Si epitaxy (ISDSE)
