Method of making electrode-to-electrode bond structure

摘要

A process of making an electrode-to-electrode bond structure includes a step of forming a resin coating on a first bonding object having a first electrode portion in a manner such that the resin coating covers the first electrode portion. Then, an opening is formed in the resin coating to expose the first electrode portion. Then, the opening is filled with a metal paste containing a metal and a resin component. Then, the first bonding object is placed on a second bonding object having a second electrode portion in a manner such that the metal paste filled in the opening faces the second electrode portion while the resin coating contacts the second bondingobject. Finally, heat-treatment isperformedtocause the first electrode portion and the second electrode portion to be electrically connected with each other via the metal while causing the resin coating to harden.
