Patent ID: 7022399

Claim:
A semiconductor device integrated multilayer wiring board comprising a plurality of wiring substrates laminated together, each of said plurality of wiring substrates including: an insulating substrate consisting substantially of a thermoplastic resin composition having, as primary constituents, a polyarylketone resin with a crystalline melting peak temperature of at least 260° C. and an amorphous polyetherimide resin; a first conductive wiring embedded within one or more grooves formed in a surface of said insulating substrate, said first conductive wiring having a surface which is substantially flush with said surface of said insulating substrate; and a second conductive wiring comprising a cured conductive paste disposed within via holes in said the insulating substrate, for electrically connecting said wiring substrates to each other, wherein insulating substrates includes a semiconductor device accommodated in an aperture formed therein, wherein at least one horizontal surface of said semiconductor device is flush with a surface of said first conductive wiring, wherein a thickness of said first conductive wiring is less than that of said semiconductor device, and wherein said wiring substrates are laminated and bonded together.
