Patent ID: 7241641

Claim:
A manufacturing method comprising: (1) obtaining a first integrated circuit structure comprising: a semiconductor substrate; one or more first conductive contact pads protruding out at a surface of the first integrated circuit structure; (2) obtaining a first substrate comprising a circuit which comprises one or more first conductive contact pads, wherein at least a portion of each of the one or more first contact pads of the first substrate is located in a corresponding via in a surface of the first substrate, the portion having a first surface facing a sidewall of the via and a second surface opposite to the first surface, the second surface facing an interior of the via and extending upward along the sidewall; (3) inserting the protruding first contact pads of the first integrated circuit structure into the corresponding vias of the first substrate and attaching the protruding first contact pads of the first integrated circuit structure to the first contact pads of the first substrate.
