| 摘要 |
A semiconductor device and a method of manufacturing a semiconductor device. A semiconductor device may include a substrate and a laterally diffused metal oxide semiconductor (LDMOS) device. A semiconductor device may include a second conductive type well formed on and/or over a substrate. An LDMOS device may include a drain disposed on and/or over a substrate. An LDMOS device may include a field oxide at one side of a drain, a first conductive type impurity layer on and/or over a substrate, under a field oxide, and/or a second conductive type impurity layer between a first conductive type impurity layer and a field oxide.
