WAFER-LEVEL LENS MODULE AND IMAGE PICKUP MODULE INCLUDING THE SAME
First Claim
1. A wafer-level lens module comprising:
- a first wafer-scale lens comprising a first substrate and a glass lens comprising a glass material and formed on a first side of the first substrate; and
a second wafer-scale lens spaced a predetermined distance from the first wafer-scale lens, the second wafer-scale lens comprising a second substrate and a first polymer lens comprising a polymer material and formed on a first side of the second substrate.

Abstract
Provided are a wafer-level lens module and an image pickup module including the same. The wafer lens module includes a plurality wafer-scale lenses. At least one of the plurality of wafer-scale lenses, such as a wafer-scale lens positioned toward an object side, includes a substrate and a glass lens element formed on one side of the substrate. The glass lens element may be a one-sided lens or a double-sided lens. When the glass lens is a double-sided lens, the substrate may have a through hole. The remaining wafer-scale lenses each include a substrate and polymer lens elements made of UV curable polymer and formed on both sides of the substrate. Also, spacers are interposed between the wafer-scale lenses, along the edge portions of the substrates, so as to maintain predetermined intervals between the wafer-scale lenses.
