摘要： Disclosed are a power semiconductor device and a method for manufacturing the same. The power semiconductor device has a PIP capacitor and an LDMOS transistor, the LDMOS transistor having second and third gate electrodes separate from a first gate electrode, which may be formed in the process of forming the upper electrode of the PIP capacitor, so it is possible to realize an LDMOS having a higher breakdown voltage and lower Ron and Rsp without additional processing. A drain voltage, which may be different from a voltage applied to the first gate electrode, may be applied to the third gate electrode, so it is possible to realize an LDMOS having a high breakdown voltage and low Ron and Rsp.
