THE INVENTION
The disclosed invention relates generally to semiconductor electronic
circuits, and, more particularly, to an electronic circuit with an electrical
hole insulator (Specification 1).
Independent claim 1 is illustrative:
1. An electronic circuit, comprising:
a semiconductor substrate;
a first layer in a fixed physical relation to the semiconductor
substrate;
a well formed in the first layer, wherein the well comprises a
first conductivity type and has a side dimension and a bottom
dimension;
a first enclosure surrounding the side dimension and the bottom
dimension of the well, wherein the first enclosure comprises a second
conductivity type complementary of the first conductivity type and
has a side dimension and a bottom dimension; and
a second enclosure surrounding the side dimension and the
bottom dimension of the first enclosure, wherein the second enclosure
comprises the first conductivity type.
