Application 10/178,008
… In one embodiment, injection molding is used to produce
new substrates having the same recessed pattern as the master.
The new substrate is typically formed out of plastic or glass
although other moldable materials…are suitable. Finally, a
series of layers is applied to the new substrate (step 150).
These layers provide the desired electrical properties of the
microelectronic device.
FIG. 2A is a top view of a portion of a substrate 200
having a microscopic recessed pattern constructed in
accordance with the present invention. Typically, feature sizes
will range from hundreds of nanometers to microns, but larger
and smaller features are possible….Substrate 200 can be
formed from the master by injection molding or itself could be
the master used to create the form…
5. Shepard teaches that its injection molding technique is taught to be
more economical than a lithography technique for patterning, such as that
employed in preparing the mold surface (stamp master) exemplified in
Kumar (col. 1, ll. 15-40).
VI. PRINCIPLES OF LAW
Under 35 U.S.C. §103, the obviousness of an invention cannot be
established by combining the teachings of the prior art references absent
