at 1551, 1553, 220 USPQ at 311, 312-13. In addition, our
reviewing court requires the Patent Trademark Office to make
specific findings on a suggestion to combine prior art
references. In re Dembiczak, 175 F.3d 994, 1000-01, 50 USPQ2d
1614, 1617-19 (Fed. Cir. 1999).
We further fail to find that Appellants’ prior art
admissions, Asano, or Fisher suggest to those skilled in the
art to provide a non-transparent electrode connected to the
drain region which would completely overlap the channel
region. We agree that Asano does suggest to those skilled in
the art to provide a partial overlapping of the channel region
in an NPN transistor. However, the Examiner has not
addressed why one of ordinary skill in the art would be led to
use this teaching with a thin film transistor matrix of Fisher
and the admitted prior art.
