Appellants have appealed to the Board from the examiner’s
final rejection of claims 1-4. Claims 5-7 have been made
subject to a restriction requirement.
Representative claim 1 is reproduced below:
1. A semiconductor device exploiting a multiply connected
quantum interference effect comprising:
(a) a semiconductor body;
(b) n - 1 (n $ 3) rods of forbidden regions extending
along one direction in said semiconductor body;
(c) a single continuous channel region consisting of
a plurality of contiguous elemental channel regions, said
forbidden regions being provided to divide said channel region
into said plurality of elemental channel regions, each of said
elemental channel regions forming a continuous closed circuit
and surrounding each of said forbidden regions, said channel
regions being multiply connected with multiplicity of n and
having (n - 1)-fold rotational symmetry around said one
direction;
(d) a gate electrode surrounding plural side walls of
said channel region; and
(e) source and drain electrodes electrically connected to
one and another end of said channel region along said one
direction.
The following references are relied on by the examiner:
