    摘要: Apparatus and methods for forming semiconductor assemblies. An interposer includes a perimeter wall surrounding at least a portion of an upper surface thereof to form a recess. An array of electrical connection pads is located within the recess. A semiconductor die can be flip chip attached to the interposer by at least partial insertion of the semiconductor die within the recess with discrete conductive elements between bond pads of the semiconductor die and electrical connection pads of the interposer. The electrical connection pads communicate with a number of other electrical contact pads accessible elsewhere on the interposer, preferably on a lower surface thereof. A low viscosity underfill encapsulant is disposed between the semiconductor die and the interposer and around the discrete conductive elements by permitting the same to flow into the space between the die and the perimeter wall. The encapsulant may form an underfill or substantially encapsulate the semiconductor die within the recess of the interposer.

    摘要: The present invention is directed toward methods and apparatuses for encapsulating a microelectronic die or another type of microelectronic device. One aspect of the present invention is directed toward packaging a microelectronic die that is attached to either a first surface or a second surface of a substrate. The die can be encapsulated by positioning the die in a cavity of a substrate and sealing the substrate to the substrate. The method can further include injecting an encapsulation compound into the cavity at a first end of the substrate to move along the first surface of the substrate. This portion of the compound defines a first flow of compound along the first surface that moves in a first direction from a first end of the substrate toward a second end of the substrate. Several embodiments of the method also include driving a portion of the compound through the substrate at a pass-through location or a secondary gate that is spaced apart from the first end of the substrate to generate a second flow of compound along the second surface of the substrate. The second flow of compound moves in a second direction toward the first end of the substrate. As the first and second flows of compound move through the mold, the method includes inhibiting a third flow of compound from moving in the first direction along the second surface of the substrate between the first end of the substrate and the pass-through location.
