Patent attributes
A method is provided for fabricating an LDMOS transistor. The method includes providing a base substrate. The method also includes forming a first well area doped with a first well ion in the base substrate. In addition, the method includes forming a second well area doped with a second well ion in the base substrate, where the second well area includes a first region adjacent to the first well area. Moreover, the method includes forming a first ion doping region doped with first ions in the first well area and the first region, where a type of the first ions is the same as a type of the first well ion and opposite to a type of the second well ion. Further, the method includes forming a gate structure on part of the first well area and part of the first region.
