Semiconductor devices and methods of manufacturing semiconductor devices

A semiconductor device, comprising:

• a spacer substrate comprising,
• a spacer dielectric;
• a spacer top terminal on a top side of the spacer substrate;
• a spacer bottom terminal on a bottom side of the spacer substrate;
• and
• a spacer via in the spacer dielectric and coupled with the spacer top terminal and the spacer bottom terminal;
• a first lens substrate over the first spacer substrate, the first lens substrate comprising,
• a first lens dielectric;
• a first lens;
• a first lens top terminal on a top side of the first lens dielectric;
• a first lens bottom terminal on a bottom side of the first lens dielectric;
• and
• a first lens via in in the first lens dielectric and coupled with the first lens top terminal and the first lens bottom terminal;
• a lens protector over the first lens dielectric adjacent to the first lens;
• and
• a first interconnect coupled with the spacer top terminal and the first lens bottom terminal.
