Patent ID: 8153957

Claim:
An integrated optical imaging system, comprising: a first substrate having first and second opposing surfaces; a second substrate having third and fourth opposing surfaces; a spacer between a substantially planar portion of the third surface of the second substrate and a substantially planar portion of the second surface of the first substrate, the spacer having a hole therein to define an interior space between the first and second substrate, and at least two of the spacer, the first substrate and the second substrate sealing the interior space between the third surface of the second substrate and the second surface of the first substrate; an optical imaging system having n surfaces, where n is greater than or equal to two, at least one of the n surfaces of the optical imaging system is on respective ones of the first, second, third and fourth surfaces; an optoelectronic device on one of the third and fourth surfaces, wherein a periphery of the spacer is equal to or less than a periphery of both the first and second substrates; and at least one metalization pad on a respective one of the first, second, third, and fourth surfaces, the metallization pad being configured to indicate an alignment position with respect to a predetermined element, and at least one of the optical imaging system and the optoelectronic device is connected to a respective one of the first, second, third, and fourth surfaces via the metalization pad.
