Abstract:
A Lateral Diffusion Metal Oxide Semiconductor (LDMOS) device and its manufacturing method are presented. The LDMOS device comprises a first region that has a first conductivity type; a drift region that has a second conductivity type in the first region, wherein the second conductivity type is opposite to the first conductivity type; and a plurality of second regions that have the first conductivity type in the drift region, wherein the second regions are separated from each other and extend to the first region along a depth direction of the drift region. This LDMOS device has an higher Breakdown Voltage and thus better performance than conventional LDMOS devices.

Claim (Index 16):
The method of  claim 10 , further comprising:\n forming a well region that has the first conductivity type in the first region when forming the drift region, wherein the well region and the drift region are separated from each other.
