Lens Plate For Wafer-Level Camera And Method Of Manufacturing Same

摘要

A lens plate includes a transparent substrate wafer, and a plurality of lenses and spacers that are formed of a single portion of material on the transparent substrate wafer. An assembly includes a first lens plate that includes a first transparent substrate wafer, a plurality of first lenses and a plurality of spacers, the first lenses and spacers being formed of a single portion of material on said first transparent substrate wafer. The assembly also includes a second lens plate that includes a second transparent substrate wafer and a plurality of second lenses formed thereon, each of the plurality of second lenses corresponding to a respective one of the plurality of first lenses. The lens plates are aligned such that each of the plurality of first lenses aligns with the respective one of the plurality of second lenses, and the lens plates are bonded to one another.

主权项

1. A method for making a lens plate comprising:
dispensing a first portion of material onto a tool that forms recesses corresponding to spacers and lenses, disposing a first side of a transparent substrate wafer onto said first portion of material, adjusting a position of said transparent substrate wafer to provide said first portion of material with a spacer thickness and a lens thickness for each of the spacers and lenses respectively, and curing the first portion of material.
