Contact lens having an uneven embedded substrate and method of manufacture
First Claim
1. A contact lens, comprising:
- a polymer;
a substrate positioned in the polymer, wherein the substrate comprises a first region having a first thickness and a second region having a second thickness, wherein the first thickness is greater than the second thickness, and wherein the polymer has a non-uniform height above the substrate;
a sensor positioned on the substrate; and
a chip positioned on the substrate.

Abstract
Contact lenses and methods of manufacturing contact lenses are provided. In one aspect, a method includes: forming a substrate having an uneven surface; providing a sensor at a first region of the substrate; providing a chip at a second region of the substrate; and encapsulating the substrate, sensor and chip in a polymer. The method also includes: patterning interconnections from the first region of the substrate to the second region of the substrate; and patterning metal pads proximate to the second region of the substrate. The chip can be provided on a metal pad. The uneven surface can be a sloped surface or one or more sloped channels in the substrate, and the channels can be wide enough to receive interconnections for the chip and to receive the chip. Further, the substrate can be ring-shaped and curved prior to encapsulation.
