Abstract

A multi-chip integrated circuit (IC) package is provided which is configured to protect against failure due to warpage. The IC package may comprise a substrate, a level-one IC die and a plurality of level-two IC dies. The level-one IC die having a surface that is electrically coupled to the substrate. The plurality of level-two IC dies is stacked above the level-one IC die. The plurality of level-two IC dies may each have an active surface that is electrically coupled to the substrate. The plurality of level-two IC dies may be arranged side by side such that the active surfaces of the plurality of level-two IC dies are positioned substantially in a same plane. Relative to a single die configuration, the level-two IC dies are separated thereby inhibiting cracking, peeling and/or other potential failures due to warpage of the IC package.
