METHODS OF PRODUCING PHOTOSENSITIVE CERAMIC COMPOSITION AND MULTI-LAYER SUBSTRATE
USING IT |
(57) The present invention relates to a photosensitive ceramic composite and a method
for manufacturing a multilayer substrate using the composite. The photosensitive ceramic
composite and manufacturing method of the present invention are applicable to circuit
members and components for ceramic multilayer substrates for high-frequency wireless
communication.
The photosensitive ceramic composite contains inorganic particles and a photosensitive
organic component. The inorganic particles have at least surface sections containing
an inorganic material having a refractive index less than that of inner sections of
the inorganic particles.
