    摘要: A method for flip-chip bonding of two electronic components (27,28) does not use a flux material. A substrate (13) of one electronic component (28) is roughened during processing to provide an improved adhesive surface for a solder ball (12). The roughened pattern is replicated by additional conductive layers formed over the substrate or in an alternate embodiment may be formed on one of the intermediary or top conductive layers. Tacking pressure is applied to the two components so the solder ball (12) will be affixed to the roughened surface and provide a temporary bond. This bond ensures the surfaces of the two electrical components remain in contact with each other during reflow of the solder ball (12) to form a permanent bond.

    摘要: A method of packaging an electronic component includes forming a hole (24) in a substrate (21) having a first surface (22) opposite a second surface (23) and disposing and patterning a malleable layer (26) over the first surface (22) and over the hole (24) of the substrate (21). The malleable layer (26) has a third surface (27) opposite a fourth surface (28). A portion (29) of the fourth surface (28) is exposed by the hole (24) in the substrate (21). An electrically conductive layer is simultaneously disposed over the portion (29) of the fourth surface (28) and over a different portion of the third surface (27) of the malleable layer (26). The malleable layer (26) is deformed into the hole (24). Then, a semiconductor die (43) is coupled to the malleable layer (26), and an underencapsulant (37) is disposed under the semiconductor die (43) and over the hole (24).

    摘要: A multi-tiered IC device contains a first die including a substrate with a first and second set of vias. The first set of vias extends from one side of the substrate, and the second set of vias extend from an opposite side of the substrate. Both sets of vias are coupled together. The first set of vias are physically smaller than the second set of vias. The first set of vias are produced prior to circuitry on the die, and the second set of vias are produced after circuitry on the die. A second die having a set of interconnects is stacked relative to the first die in which the interconnects couple to the first set of vias.

    摘要: By constructing a universal test circuit on a tester chip, and stacking the tester chip in an IC package together with operational circuit chips to be tested, the problems inherent with external IC testing are reduced. The tester chip can be standardized across a number of different chip combinations and, if desired, pre-programmed during manufacturing for a particular package. The tester chip interfaces to other chips in the stack advantageously are standardized.
