Wafer-Level Hybrid Compound Lens And Method For Fabricating Same

摘要

A hybrid compound lens includes a substrate lens and a resin lens. The substrate lens has a non-planar substrate surface surrounded by a flange having a flange surface bordering the non-planar substrate surface and forming an obtuse angle therewith. The resin lens has a non-planar resin surface adjoining the substrate lens along the non-planar substrate surface. A lens wafer includes a substrate wafer and resin lenses. The substrate wafer has a top surface having non-planar surface features each bordered by a planar region of the top surface and forming an obtuse angle therewith. Each resin lens has a non-planar resin surface adjoining the substrate wafer along a non-planar surface feature. A method for fabricating a wafer-level hybrid compound lens includes depositing a resin portion on a non-planar feature of a side of a substrate. The method also includes forming the resin portion into a lens on the non-planar feature.

1. A hybrid compound lens comprising:
a substrate lens having a first non-planar substrate surface surrounded by a flange having a flange surface bordering the first non-planar substrate surface, the flange surface forming an obtuse angle with the first non-planar substrate surface; and a resin lens having a first non-planar resin surface that adjoins the substrate lens along the first non-planar substrate surface.
