Application No. 09/196,375
for all of the transistors on the integrated circuit to achieve the increased density. While
Akcasu teaches the varied thickness for reducing capacitance and increasing density,
we find no teaching or suggestion that these benefits may be achieved with one varied
thickness transistor and one uniform transistor. Therefore, we find that the examiner
has not established that the combination of teachings would have taught or suggested
the use of one transistor with a buried region of varied thickness and one transistor with
a buried region uniform thickness transistor, and we cannot sustain the rejection of
independent claim 3 and its dependent claims 4, 5, and 8-10.
CONCLUSION
To summarize, the decision of the examiner to reject claims 3-5 and 8-10 under
35 U.S.C. § 103 is reversed.
