摘要： 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. One of either the p-well region or the n-well region is masked with a patterned photoresist having a prescribed thickness, leaving a non-masked region exposed. Ions are then implanted to form desired p-type lightly doped drain (Pldd) regions in the n-well region, including Pldd regions adjacent to edges of the gate electrode in the n-well region. Lastly, ions are implanted to form desired n-type lightly doped drain (Nldd) regions in the p-well region, including Nldd regions adjacent to edges of the gate electrode in the p-well region, the Pldd and Nldd regions thus being formed with the use of only a single ion implantation masking step. A semiconductor substrate and an integrated circuit are also disclosed.

摘要： A MOS integrated circuit device fabricated utilizing high energy, high current implanting of ions through a layer of oxide to form heavily doped source and drain regions which are self-aligned with a polysilicon gate. A thick portion of the oxide layer adjacent to the polysilicon gate prevents heavy doping in the substrate next to the gate. The oxide layer is removed and a lightly doped drain (LDD) implant forms an LDD region which is self-aligned with the gate. Using this method the source/drain and LDD implants are performed using only a single mask and etch operation, rather than two mask and etch operations which are necessary using a conventional process.
