Abstract
A sensor device, a sensor package, and method for fabricating a sensor device are described that include an integrated light blocker disposed on the thermopile device and a lens configured to direct light to the thermopile device. In an implementation, the thermopile device includes a substrate; a thermopile membrane disposed on the substrate, the thermopile membrane including at least one passivation layer; a thermopile disposed within the thermopile membrane, the thermopile including at least one thermocouple; and a light blocking layer disposed proximate to the thermopile membrane, the light blocking layer including an aperture disposed proximate to the thermopile.
