Embodiments of laterally diffused metal oxide semiconductor (LDMOS) transistors are provided. An LDMOS transistor includes a substrate having a source region, channel region, and a drain region. A first implant is formed to a first depth in the substrate. A gate electrode is formed over the channel region in the substrate between the source region and the drain region. A second implant is formed in the source region of the substrate; the second implant is laterally diffused under the gate electrode a predetermined distance. A third implant is formed to a second depth in the drain region of the substrate; the second depth is less than the first depth.

Methods of forming laterally diffused metal oxide semiconductor transistors for radio frequency power amplifiers

Deuterated compounds are used to form passivation (20) and other insulating layers to reduce the hydrogen content within those films. Semiconductor source gases, nitride source gases, and dopant gases can be obtained in deuterated form. Process steps for forming and etching are substantially the same as those used to form and etch conventional insulating layer. A sintering step can be performed using deuterated gas or omitted altogether.
