Appeal No. 96-0471
Application 07/995,582
a base-collector junction connecting the base region
and the collector region, wherein the buffer region is
located adjacent to the sidewalls, thereby shifting the
base-collector junction towards the collector region and
away from the sidewalls.
The examiner relies on the admitted prior art in
appellant's figure 1, described at page 2, lines 11-15, of the
specification and the following prior art patent:
Tasch, Jr. et al. (Tasch) 4,153,904 May 8, 1979
Amended drawing figures 2 and 3 are objected to on the
basis that the specification does not teach that the boundary
between the base region (claim 1) or the first polarity region
(claim 11) and the buffer region is a straight line.
The specification is objected to and claims 1, 4-11,
and 14-20 stand rejected under 35 U.S.C. § 112, first
paragraph, as lacking written description support for the base
region extending to the sidewalls of the deep trench as
recited in claim 1 and for the first polarity region extending
to the sidewalls of the deep trench as recited in claim 11.
