Abstract:
Semiconductor device and methods for making the devices includes a buried layer of a first conductivity in a substrate in which a distance between two adjacent ends can be selected to achieve a desired breakdown voltage. A deep well having a first doping concentration of a second conductivity type is implanted in an epitaxial layer above the two adjacent ends of the buried layer. A patterned doped region is formed in the deep well and extending into the epitaxial layer above and separated a distance from the two adjacent ends of the buried lay. The patterned doped region has a second doping concentration of the second conductivity type that is greater than the first doping concentration.

Claim (Index 8):
The semiconductor device of  claim 1 , further comprising:\n the patterned buried layer further including a third portion and a fourth portion, wherein the third and fourth portions each have a first end and a second end, the first ends having a smaller cross-section than the second ends, and the first ends with the smaller cross-section are adjacent to one another; a second deep well in the substrate having the second conductivity type and the first doping level, wherein the second deep well is separated from the patterned buried layer; a patterned doped region in the second deep well directly over the first ends of the third and fourth portions of the patterned buried layer, the patterned doped region having the second conductivity type and the second doping level that is greater than the first doping level.
