Abstract:
A superjunction power semiconductor device includes a termination region with superjunction structures having higher breakdown voltage than the breakdown voltage of the active cell region. In one embodiment, the termination region includes superjunction structures having lower column charge as compared to the superjunction structures formed in the active cell region. In other embodiments, a superjunction power semiconductor device incorporating superjunction structures with slanted sidewalls where the grading of the superjunction columns in the termination region is reduced as compared to the column grading in the active cell region. The power semiconductor device is made more robust by ensuring any breakdown occurs in the core region as opposed to the termination region. Furthermore, the manufacturing process window for the power semiconductor device is enhanced to improve the manufacturing yield of the power semiconductor device.

Claim (Index 7):
The superjunction power semiconductor device of  claim 6 , wherein the second column width is less than the first column width.
