Abstract:
A laterally diffused metal oxide semiconductor (LDMOS) device includes a substrate having a p-epi layer thereon, a p-body region in the p-epi layer and an ndrift (NDRIFT) region within the p-body to provide a drain extension region. A gate stack includes a gate dielectric layer over a channel region in the p-body region adjacent to and on respective sides of a junction with the NDRIFT region. A patterned gate electrode is on the gate dielectric. A DWELL region is within the p-body region. A source region is within the DWELL region, and a drain region is within the NDRIFT region. An effective channel length (Leff) for the LDMOS device is 75 nm to 150 nm which evidences a DWELL implant that utilized an edge of the gate electrode to delineate an edge of a DWELL ion implant so that the DWELL region is self-aligned to the gate electrode.

Claim (Index 20):
A laterally diffused metal oxide semiconductor (LDMOS) device, comprising:\n a substrate; a p-epi layer disposed on the substrate; a p-body region disposed in the p-epi layer; an NDRIFT region disposed in the p-body region to provide a drain extension region; a gate dielectric layer disposed over a channel region in the p-body region, wherein the gate dielectric layer extends from a first end over the NDRIFT region to a second end over a portion of the p-body region outside of the NDRIFT region so that the gate dielectric layer is disposed over a junction between the NDRIFT region and the p-body region; a gate electrode disposed over the gate dielectric layer; a DWELL region disposed in the p-body region and having an edge delineated by the an edge of the gate electrode, wherein an effective channel length between the edge of the DWELL region and the junction between the NDRIFT region and the p-body region is between approximately 75 nm and 150 nm; a source region disposed in the DWELL region; and a drain region disposed in the NDRIFT region.
