STACKED LENS STRUCTURE, METHOD OF MANUFACTURING THE SAME, AND ELECTRONIC APPARATUS

Title:

STACKED LENS STRUCTURE, METHOD OF MANUFACTURING THE SAME, AND ELECTRONIC APPARATUS

Document Type and Number:

WIPO Patent Application WO/2017/022188

Kind Code:

A1

Abstract:

A deformation of a stacked lens is suppressed. 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 bonded and stacked by direct bonding. 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.
