20130082372 | Package on Packaging Structure and Methods of Making Same - A package on packaging structure provides for improved thermal conduction and mechanical strength by the introduction of a sold thermal coupler between the first and second packages. The first package has a first substrate and through vias through the first substrate. A first set of conductive elements is aligned with and coupled to the through vias of the first substrate. A solid thermal coupler is coupled to the first set of conductive elements and to a die of the second package. A second set of conductive elements is coupled to the die and a bottom substrate is coupled to the second set of conductive elements. The thermal coupler may be, e.g., an interposer, a heat spreader, or a thermal conductive layer. | 04-04-2013 |
20130087892 | Electrical Connection for Chip Scale Packaging - A system and method for providing a post-passivation opening and undercontact metallization is provided. An embodiment comprises an opening through the post-passivation which has a first dimension longer than a second dimension, wherein the first dimension is aligned perpendicular to a chip's direction of coefficient of thermal expansion mismatch. By shaping and aligning the opening through the post-passivation layer in this fashion, the post-passivation layer helps to shield the underlying layers from stresses generated from mismatches of the materials' coefficient of thermal expansion. | 04-11-2013 |
