  • Publication number: 20190326389
    Abstract: Methods for manufacturing a MOSFET device for high voltage application are disclosed to solve less-than-90-degree trench angle problem. In one embodiment, the trenches in a MOSFET device are filled with different concentrations of P? epitaxial material at different stages to improve charge balance. In an alternative embodiment, several N? epitaxial layers with different concentrations are created before etching trenches filled with P? epitaxial material. Yet in another embodiment, a reverse deep trench process creates a P? epitaxial layer first, and etches wider conductive regions to be filled with N? epitaxial later, leaving the remaining P? epitaxial columns as non-conductive regions similar to the traditional P? epitaxial trenches.
