Patent ID: 7324717

Claim:
An assembly comprising: a light emitting/detecting integrated circuit (IC) device including a substrate having a planar upper surface, and at least one light emitting/detecting element integrally fabricated on the substrate adjacent to the upper surface; and a microlens structure including a pedestal having a planar lower surface and a plurality of legs extending from the lower surface, and at least one microlens integrally fabricated on the lower surface of the microlens structure; wherein the microlens structure is mounted onto the upper surface of the light emitting/detecting device such that each of the plurality of legs contacts a corresponding region of the upper surface of the substrate, whereby the microlens is maintained at a predetermined distance from the light emitting/detecting element, wherein the microlens structure further comprises a carrier plate, and wherein the pedestal comprises a base section connected to the central region of the carrier plate, and a free end section extending from the base section away from the carrier plate, and wherein the lower surface is located at an end of the free end section.
