Patent ID: 6856008

Claim:
A multilayer package comprising: a first substrate including: a first conductive pad and a first conductive layer disposed in the first substrate; and a first via extending through at least a portion of the first substrate and providing an electrical connection between the first conductive pad and the first conductive layer; a second substrate including: a second conductive pad and a second conductive layer disposed in the second substrate; and a second via extending through at least a portion of the second substrate and providing an electrical connection between the second conductive pad and the second conductive layer; an adhesive film disposed between the first substrate and the second substrate and having an aperture located at least in part between the first and second conductive pads, the adhesive film mechanically bonding the first substrate and the second substrate; and a solder segment occupying at least a substantial portion of the aperture in the adhesive film and providing an electrical connection between the first conductive pad and the second conductive pad, the solder segment being formed at least in part by a reflow of solder paste applied to the first conductive pad.
