摘要

The pin-pin device includes an n-doped source and / or drain extension disposed between the bulk semiconductor portion of the semiconductor substrate on which the n-doped source or drain extension is disposed and the gate spacer of the pin-pin. An n-doped source or drain extension is formed by a selective epitaxial growth (SEG) process of the cavity formed proximate to the gate spacer.
