STACKED LENS STRUCTURE, METHOD OF MANUFACTURING THE SAME, AND ELECTRONIC APPARATUS
Substrates with lenses having lenses disposed therein are aligned with high accuracy. A stacked lens structure has a configuration in which substrates with lenses having a lens disposed on an inner side of a through-hole formed in the substrate are direct-bonded and stacked based on an alignment mark. The alignment mark is formed simultaneously with the through-hole. The present technique can be applied to a camera module or the like in which a stacked lens structure in which at least three substrates with lenses including first to third substrates with lenses which are substrates with lenses in which a through-hole is formed in the substrate and a lens is formed on an inner side of the through-hole is integrated with a light receiving element, for example.
Method for producing optical article with anti-reflective surface, and optical article with anti-reflective surface
Methods for forming optical articles with antireflective nanostructured (ARN) surfaces. An aluminum layer is deposited or otherwise applied to the cavity of an injection mold tool. Sequential chemical treatments such as anodization and etching steps form an ARN mold texture on the interior surface of the cavity. The ARN mold texture is a negative of a desired surface texture of the article. During injection molding, the desired ARN surface is thereby produced in the optical article.
LENS-ATTACHED SUBSTRATE, STACKED LENS STRUCTURE, CAMERA MODULE, AND MANUFACTURING APPARATUS AND METHOD
To suppress occurrence of contamination or damage to a lens. In the present technology, for example, a manufacturing apparatus allows a spacer which is thicker than a height of a lens resin portion protruded from a substrate to be adhered to the substrate. In addition, for example, in the present technology, the manufacturing apparatus molds the lens resin portion inside a through-hole formed in the substrate by using a mold frame configured with two layers of molds and, after molding the lens resin portion, in the state that one mold is adhered to the substrate, the manufacturing apparatus demolds the substrate from the other mold. The present technology can be applied to, for example, a lens-attached substrate, a stacked lens structure, a camera module, a manufacturing apparatus, a manufacturing method, an electronic apparatus, a computer, a program, a storage medium, a system, or the like.

Fabrication of optics wafer
Fabricating an optics wafer includes providing a wafer comprising a core region composed of a glass-reinforced epoxy, the wafer further comprising a first resin layer on a top surface of the core region and a second resin layer on a bottom surface of the core region. The wafer further includes vertical transparent regions that's extend through the core region and the first and second resin layers. The wafer is thinned from its top surface and its bottom surface so that a resulting thickness is within a predetermined range without causing glass fibers of the core region to become exposed. Optical structures ate provided on one or more exposed surfaces of at least some of the transparent regions.
