Integrated circuits including LDMOS transistor structures and methods for fabricating LDMOS transistor structures

摘要

Integrated circuits including LDMOS transistor structures and methods for fabricating LDMOS transistor structures are provided. An exemplary method for fabricating an LDMOS transistor structure includes providing a semiconductor-on-insulator (SOI) substrate including a semiconductor layer overlying an insulator layer overlying a bulk layer. The method includes forming a gate structure overlying the substrate. A channel region is formed in the semiconductor layer under the gate structure. The method includes forming a source region overlying the substrate. Further, the method includes forming a drain region overlying the substrate. A drift region is located between the drain region and the gate structure. Also, the method includes forming contacts to the gate structure, the source region, and the drain region.
