Abstract:
1. A method for forming a chip package, comprising: providing a substrate having an upper surface and a lower surface, wherein the substrate comprises at least a first contact pad; disposing a non-optical sensor chip overlying the upper surface of the substrate, wherein the non-optical sensor chip comprises at least a second contact pad and has a first length; disposing a spacer structure overlying the non-optical sensor chip; disposing a protective cap overlying the spacer structure, wherein the protective cap has a second length, an extending direction of the second length is substantially parallel to an extending direction of the first length, and the second length is shorter than the first length, wherein the spacer structure defines a space between the protective cap and the non-optical sensor chip, and wherein the protective cap, the spacer structure and the non-optical sensor chip together surround a sealed space; disposing an IC chip overlying the protective cap, wherein the IC chip comprises at least a third contact pad, the IC chip has a third length, and an extending direction of the third length is substantially parallel to the extending direction of the first length; and forming a plurality of bonding wires, wherein the bonding wires form electrical connections between the substrate, the non-optical sensor chip, and the IC chip.
