Patent ID: 6849915

Claim:
A light sensitive semiconductor package, comprising: a chip carrier having an upper surface and an opposite lower surface, wherein the chip carrier is formed with a through hole penetrating therethrough; at least one first chip mounted on the upper surface of the chip carrier and over the through hole with the first chip electrically connected to the upper surface of the chip carrier; at least one second chip attached to the first chip and received in the through hole of the chip carrier, such that the second chip is electrically connected to the lower surface of the chip carrier; a dam formed on the upper surface of the chip carrier and having a cavity for receiving the first chip therein; a first light permeable member attached to the dam to seal an opening of the cavity and hermetically isolate the first chip from the atmosphere; an encapsulant formed on the chip carrier to surround the dam and encapsulate the second chip; and a second light permeable member supported by the encapsulant and disposed above the first light permeable member.
