    • A method of integrating lightly doped drain implantation for complementary metal oxide semiconductor (CMOS) device fabrication includes providing a semiconductor substrate having a p-well region and an n-well region. A patterned gate oxide and gate electrode are formed on each of the p-well region and the n-well region.
