Abstract:
1. A substrate comprising a plurality of integrated circuitry dies, individual of the integrated circuitry dies having bond pads, the substrate comprising: first passivation material comprising at least one of silicon dioxide and silicon nitride received over the integrated circuitry dies; second passivation material comprising polyimide received over the first passivation material; silicone-comprising passivation material received over the second passivation material; openings extending through the silicone-comprising passivation material, through the second passivation material and through the first passivation material to the bond pads; and a silica particle-containing resin distinct from and received over the silicone-comprising passivation material and within the openings, solid particles of the silica particle-containing resin extending from the silica particle-containing resin into the silicone-comprising passivation material.
