Patent ID: 7504637

Claim:
A two component detector, comprising: a photodiode array comprising two or more photodiodes wherein each photodiode is capable of converting light to an electrical signal; a first substrate having a first surface and a second surface opposite the first surface, wherein the first surface of the first substrate is bonded to the photodiode array, and wherein the first substrate comprises two or more analog electrically conductive paths individually routed through the first substrate leading from the first surface of the first substrate to a portion of the second surface of the first substrate, and wherein each photodiode is coupled to a unique one of the two or more electrically conductive paths at the first surface of the first substrate; a shield attached to the second surface of the first substrate; a second substrate having a first surface and a second surface wherein a portion of the first surface of the second substrate is joined to the portion of the second surface of the first substrate coupling each one of the two or more analog electrically conductive paths of the first substrate to a unique one of two or more analog electrically conductive paths individually routed through the second substrate; a die comprising circuitry for processing each electrical signal wherein the die is directly flip chip attached to the first surface of the second substrate coupling each unique analog electrically conductive path in the second substrate to the die; and two or more digital electrically conductive paths individually routed through the second substrate coupling the die to a passive electronic component directly attached to the second surface of the second substrate, said digital electrically conductive paths being isolated from the analog electrically conductive paths.
