摘要： Underfill flow guide structures and methods of using the same are provided with a module. The method includes mounting bumps on a substrate. The method also includes forming underfill flow guide structures on the substrate by patterning wires with an overlay of hard substance. The underfill flow guide structures are integrated with the substrate and formed between adjacent bumps. The underfill flow guide structures are further formed to uniformly guide underfill along the substrate during capillary underfill processing.

摘要： Disclosed is a chip and method of forming the chip with improved conductive pads that allow for flexible C4 connections with a chip carrier or with another integrated circuit chip. The pads have a three-dimensional geometric shape (e.g., a pyramid or cone shape) with a base adjacent to the surface of the chip, a vertex opposite the base and, optionally, mushroom-shaped cap atop the vertex. Each pad can include a single layer of conductive material or multiple layers of conductive material (e.g., a wetting layer stacked above a non-wetting layer). The pads can be left exposed to allow for subsequent connection to corresponding solder bumps on a chip carrier or a second chip. Alternatively, solder balls can be positioned on the conductive pads to allow for subsequent connection to corresponding solder-paste filled openings on a chip carrier or a second chip.

摘要： Disclosed herein is a solder self-assembly structure, an IC chip including a solder self-assembly structure, and a method of making the same. The structure includes a release layer disposed on a portion of an upper surface of the substrate, laterally spaced from a via in the substrate. A barrier layer metallization (BLM) is disposed in a first part over a portion of the substrate including a via, and in a second part over the release layer, leaving a surface of the substrate exposed between the first portion and the second portion of the BLM. A solder structure is disposed over the first and second portions of the BLM and the exposed surface of the substrate disposed there between. When the solder structure is reflowed and annealed, surface tension in the solder causes self-assembly of a three-dimensional, compliant solder structure.

摘要： An IC chip package, in one embodiment, may include an IC chip including an upper surface including an overhang extending beyond a sidewall of the IC chip, and underfill material about the sidewall and under the overhang. The overhang prevents underfill material from extending over an upper surface of the IC chip. In another embodiment, a ball grid array (BGA) is first mounted to landing pads on a lower of two joined IC chip packages. Since the BGA is formed on the lower IC chip package first, the BGA acts as a dam for the underfill material thereon. The underfill material extends about the respective IC chip and surrounds a bottom portion of a plurality of solder elements of the BGA and at least a portion of respective landing pads thereof.

摘要： Structures with improved solder bump connections and methods of fabricating such structures are provided herein. The structure includes a via formed in a dielectric layer to expose a contact pad and a capture pad formed in the via and over the dielectric layer. The capture pad has openings over the dielectric layer to form segmented features. The solder bump is deposited on the capture pad and the openings over the dielectric layer.
