Abstract
Backside recesses in a base member host components, such as sensors or circuits, to allow closer proximity and efficient use of the surface space and internal volume of the base member. Recesses may include covers, caps, filters and lenses, and may be in communication with circuits on the frontside of the base member, or with circuits on an active backside cap. An array of recessed components may a form complete, compact sensor system.
