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 13):
The method of  claim 11 , further comprising:\n implanting a third portion and a fourth portion of the buried layer when the first and second portions of the buried layer are implanted, wherein the third portion is separated a distance from the fourth portion of the buried layer due to the first mask; annealing the buried layer, thereby decreasing the distance between the third and fourth portions of the buried layer at the same time the distance between the first and second portions is being decreased; implanting a second deep well in the epitaxial layer of material over the third and fourth portions of the buried layer while the deep well is implanted, the second deep well having the second conductivity type of the first doping concentration; the masking the section of the substrate with the third mask includes an opening over the second deep well and the third and fourth portions of the buried layer; and implanting a second patterned doped region in the second deep well over the third and fourth portions of the buried layer, wherein the second patterned doped region extends through the second deep well into the epitaxial layer but is separated from the third and fourth portions of the buried layer by another distance.
