The appeal involves claims 1-3, 5-8, 10-21, and 31-37. Claims 1 and
16 are illustrative and are reproduced below.
1. A method comprising:
coating a core surface with an A-stage thermoset resin to
produce an A-stage thermoset resin layer, wherein the A-stage
thermoset resin is a material combined with a solvent, the material
selected from the group consisting of epoxy resins, polyimide epoxies,
bismaleimide epoxies and any combination thereof;
partially curing the A-stage resin layer to produce a partially
cured thermoset resin layer;
imprinting a plurality of conductor features into the partially
cured thermoset resin layer to produce an imprinted substrate;
completely curing the imprinted substrate to produce a fully
cured resin layer having an exposed surface;
chemically roughening the exposed surface to produce a
chemically roughened exposed surface;
applying a seed layer to the chemically roughened exposed
surface; and
plating the chemically roughened exposed surface to produce a
plated surface.
16. A method comprising:
providing a core having an upper surface and a lower surface;
coating the upper surface and lower surface with an A-stage
thermoset resin to produce upper and lower A-stage thermoset resin
layers, wherein the A-stage thermoset resin is a material combined
with a solvent, the material selected from the group consisting of
