## Abstract

Methods to form a device whereon flexible component elements are attached upon three-dimensional surfaces are described. In some aspects, the present invention includes incorporating flexible semiconductor devices onto three-dimensional surfaces with electrical contacts. In some aspects, the formed device may be incorporated in an ophthalmic device.

## Claims

### Claim 1

An ophthalmic device comprising:
an optical device component;
a substrate insert having at least a surface region that is non-planar and forms at least a portion of a cylindrical shape contoured around at least a portion of a radial path of the optical device component;
electrical contacts formed upon the surface region;
at least a first electronic element attached to the electrical contacts, wherein the first electronic element comprises a thinned flexible semiconductor bent to conform to the surface region along the portion of the cylindrical shape.

### Claim 2 (depends on 1)

The ophthalmic device of claim 1, wherein the electronic element is formed from a rectilinear-shaped material.

### Claim 3 (depends on 1)

The ophthalmic device of claim 1, wherein the device includes a second electronic element spatially separated from and redundant to the first electronic element, wherein the first and second electronic elements are connected in parallel or series.

### Claim 4 (depends on 1)

The method of claim 1, wherein the semiconductor comprises crystalline silicon, polycrystalline silicon, or amorphous silicon.

### Claim 5 (depends on 1)

The ophthalmic device of claim 1 wherein the surface region and the first electronic element are housed within a media insert at a location defined by a mold feature formed between a front optic piece and a back optic piece of the media insert.

### Claim 6 (depends on 1)

The ophthalmic device of claim 1 wherein the surface region is formed in a helical shape in three dimensions and wherein the thinned flexible semiconductor is bent in the third dimension to take on the helical shape of the substrate.

### Claim 7 (depends on 1)

The ophthalmic device of claim 1 wherein cylindrical shape of the substrate insert has a radius of within about 7 mm and 9 mm.
