    摘要: A method comprises determining a warpage of an integrated circuit (IC) package design. The IC package design includes a substrate having a top solder mask on a first major surface and a bottom solder mask on a second major surface opposite the first major surface. The first major surface has an IC die mounted over the top solder mask. The design is modified, including modifying an average thickness of one of the group consisting of the top solder mask and the bottom solder mask, so as to reduce the warpage. An IC package is fabricated according to the modified design.

    摘要: A package-on-package arrangement for maintaining die alignment during a reflow operation is provided. A first top die has a first arrangement of solder bumps. A bottom package has a first electrical arrangement to electrically connect to the first arrangement of solder bumps. A die carrier has a plurality of mounting regions defined on its bottom surface, wherein the first top die is adhered to the die carrier at a first of the plurality of mounting regions. One of a second top die and a dummy die having a second arrangement of solder bumps is also fixed to the die carrier at a second of the plurality of mounting regions of the die carrier. The first and second arrangements of solder bumps are symmetric to one another, therein balancing a surface tension during a reflow operation, and generally fixing an orientation of the die carrier with respect to the bottom package.
