Lens module and a method for fabricating the same
A lens module and a method for fabricating the same are disclosed. The module comprises a substrate and a lens structure. The substrate comprises a through-hole therein. The lens structure is embedded in the through-hole.
1. A lens module, comprising:
a substrate comprising a through-hole therein; and
a lens structure embedded in the through-hole, the lens structure comprising a lens body, a dam structure overlying at least part of the sidewalls of the through-hole and extending out of the through-hole, and a connecting component connecting the lens body and the dam structure, wherein at least a portion of the lens structure completely and directly contacts side walls of the through-hole.
2. The module as claimed in claim 1 , wherein the substrate is a glass substrate.
3. The module as claimed in claim 1 , wherein the lens structure is substantially homogeneous.
4. The module as claimed in claim 1 , wherein the dam structure surrounds the connecting component and the connecting component surrounds the lens body.
5. The module as claimed in claim 1 , wherein the lens module is disposed overlying a semiconductor substrate.
