Abstract:
The subject matter disclosed herein relates to super-junction (SJ) power devices and, more specifically, to edge termination techniques for SJ power devices. A semiconductor super-junction (SJ) device includes one or more epitaxial (epi) layers having a termination region disposed adjacent to an active region. The termination region includes a plurality of vertical pillars of a first and a second conductivity-type, wherein, moving outward from the active region, a respective width of each successive vertical pillar is the same or smaller. The termination region also includes a plurality of compensated regions having a low doping concentration disposed directly between a first side of each vertical pillar of the first conductivity-type and a first side of each vertical pillar of the second conductivity-type, wherein, moving outward from the active region, a respective width of each successive compensated region is the same or greater.

Claim (Index 22):
The method of  claim 17 , comprising:\n forming a second epi layer on the first epi layer; applying the first mask that selectively exposes a first portion of the second epi layer; implanting dopant of the first conductivity-type with the first implantation dose into the first portion of the active region and the termination region of the second epi layer; applying the second mask that selectively exposes a second portion of the second epi layer; and implanting dopant of a second conductivity-type with a second dose into the second portion of the active region and termination region of the second epi layer, wherein the first portion and the second portion overlap in the termination region to form a plurality of compensated regions directly between a plurality of vertical pillars of the first conductivity-type and a plurality of vertical pillars of the second conductivity-type in the termination region of the second epi layer.
