Appeal No. 96-0019
Application 08/150,742
This is a decision on the appeal under 35 U.S.C. § 134
from the examiner's rejection of claims 24-28. Claims 1-23 have
been cancelled. Claims 29-37 have been indicated by the examiner
as being allowable.
The claimed invention pertains to a transistor having a
plurality of active regions arranged around a central active
region. The spacing between active regions is changed as the
active regions move away from the central region. The change in
spacing is said to modify the temperature distribution at the
transistor junctions so that a more uniform temperature can be
maintained across the entire transistor.
Representative claim 24 is reproduced as follows:
24. A transistor comprising a plurality of sets of
active regions arranged about a central active region, wherein at
least two of said sets lie at unequal intervals from said central
active region, and further wherein the interval between a set
nearest said central region and said central region is
approximately 50% larger than the interval between said nearest
set and a set next-nearest to said central active region.
The examiner relies on the following references:
Fukino 3,704,398 Nov. 28, 1972
Alderstein 4,939,562 July 03, 1990
Claims 24-28 stand rejected under 35 U.S.C. § 103. As
evidence of obviousness the examiner offers Fukino in view of
Alderstein.
