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 bonding object. Finally, heat-treatment is performed to cause 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.

According to a method of making a semiconductor device, a semiconductor chip is bonded to a substrate via bumps by flip-chip bonding. Then, a sealing adhesive composition is loaded between the semiconductor chip and the substrate to provide an adhesive sealing. The sealing adhesive composition, which is capable of hardening in two stages, contains at least a first main resin ingredient, a second main resin ingredient and a hardening agent. Then, the adhesive sealing is heated for primary hardening. Then, the substrate is placed on a mother board with a solder material interposed between the substrate and the mother board. Finally, the adhesive sealing is heated for secondary hardening while the solder material is reflowed for bonding the substrate to the mother board.
