Abstract:
1. A semiconductor package comprising: a substrate having (i) a first surface, (ii) a second surface that is opposite to the first surface, and (iii) an opening formed between the first surface of the substrate and the second surface of the substrate; a semiconductor die having (i) a first surface and (ii) a second surface that is opposite to the first surface, wherein at least a part of the first surface of the semiconductor die is attached to the second surface of the substrate; a bonding wire that electrically couples the first surface of the semiconductor die to the first surface of the substrate through the opening of the substrate; a first electrically insulative structure disposed to substantially fill the opening of the substrate, wherein the first electrically insulative structure substantially encapsulates the bonding wire; and a second electrically insulative structure that comprises a material different from a material of the first electrically insulative structure, wherein the second electrically insulative structure encapsulates at least a part of the second surface of the substrate.
