Bump structures for multi-chip packaging

摘要

The mechanisms for forming a multi-chip package described enable chips with different bump sizes being packaged to a common substrate. A chip with larger bumps can be bonded with two or more smaller bumps on a substrate. Conversely, two or more small bumps on a chip may be bonded with a large bump on a substrate. By allowing bumps with different sizes to be bonded together, chips with different bump sizes can be packaged together to form a multi-chip package.

1. A chip package, comprising:
a first bump structure between a first chip and a substrate of the chip package, wherein a first solder layer of the first bump structure surrounds more than one bump on the substrate, and the solder layer covers an entirety of each sidewall of each bump of the more than one bump.
