Abstract

See full text

A method for soldering three-dimensional integrated circuits is provided. A three-dimensional integrated circuit is heated to a base temperature, wherein the base temperature is lower than the melting point of a solder, and wherein the three-dimensional integrated circuit includes a plurality of solder bumps. A first on-chip heat source reflows a first portion of the plurality of solder bumps that is within a first local-hot-zone. A second on-chip heat source reflows a second portion of the plurality of solder bumps that is within a second local-hot-zone.
