Claim 17:
18. A complementary MOSFET structure comprising:
a semiconductor wafer substrate with a semiconductor surface;
a P type MOSFET comprising a first gate structure and a first conductive region, wherein the first conductive region includes a first lightly doped semiconductor region and a highly doped P+ region laterally extending from the first lightly doped semiconductor region, and the first lightly doped semiconductor region is aligned or substantially aligned with an edge of the first gate structure;
a N type MOSFET comprising a second conductive region, wherein the second conductive region includes a highly doped N+ region; and
a localized isolation region between the P type MOSFET and the N type MOSFET,
wherein both the highly doped P+ region and the highly doped N+ region are shielded from the semiconductor wafer substrate;
wherein the first conductive region or the second conductive region further comprises a metal containing region laterally abuts against a sidewall of the highly doped P+ region or a sidewall of the highly doped N+ region.
