  • Patent number: 8022536
    Abstract: The present invention provides techniques to fabricate build-up single or multichip modules. In one embodiment, this is accomplished by dispensing die-attach material in one or more pre-etched cavities on a substrate. A semiconductor die is then placed over each pre-etched cavity including the die-attach material by urging a slight downward pressure on the substrate such that an active surface of each placed semiconductor die is disposed across from the substrate and is further substantially coplanar with the substrate. The semiconductor die is then secured to the substrate by curing the die-attach material. A miniature circuit board, including one or more alternating layer of dielectric material and metallization structures, is then formed over the substrate and the active surface of each semiconductor die to electrically interconnect the semiconductor dies.
