Abstract
Provided herein include various examples of an apparatus, flow cells that include these examples of the apparatus, and methods of making these examples of the apparatus. The apparatus can include a molding layer over a substrate and covering sides of a light detection device. The molding layer comprises a first region and a second region, which, with the active surface of the light detection device, form a contiguous surface. A waveguide integration layer is between the contiguous surface and a waveguide. The waveguide integration layer comprises optical coupling structures over the first and second regions, to optically couple light waves from a light source to the waveguide. The waveguide utilizes the light waves to excite light sensitive materials in nanowells. A nanostructure layer over the waveguide comprises the nanowells. Each nanowell shares a vertical axis with a location on the active surface of the light detection device.
