Application No. 08/263,180
all of the limitations of the base claim and any intervening
claims.
The disclosed invention relates to a hot carrier
transistor.
Claim 79 is the only independent claim on appeal, and it
reads as follows:
79. A hot carrier transistor, comprising:
(a) an emitter;
(b) a base;
(c) a collector, said collector forming a
heterojunction with said base; and
(d) an injector connected between said emitter and
said base, said injector including tunneling barriers
with bandgap larger than the bandgaps of said emitter and
of said base and also including a quantum well between said
tunneling barriers with a portion having a bandgap
smaller than the bandgaps of said emitter and of said base.
The reference relied on by the examiner is:
Yokoyama 4,712,121 Dec. 8,
1987
Claims 79 and 81 stand rejected under 35 U.S.C. § 102(b)
as being anticipated by Yokoyama or, in the alternative, under
35 U.S.C. § 103 as being unpatentable over Yokoyama.
Reference is made to the brief and the answer for the
respective positions of the appellant and the examiner.
