Abstract
A radiation sensor () includes a radiation sensor chip () including first () and second () thermopile junctions connected to form a thermopile (). The first thermopile junction is disposed in a floating portion of a dielectric membrane () thermally insulated from a silicon substrate () of the chip, and the second thermopile junction is disposed in the dielectric membrane directly adjacent to the substrate. Bump conductors () are bonded to corresponding bonding pads (A) coupled to the thermopile () to physically and electrically connect the chip to conductors on a printed circuit board (). The silicon substrate transmits infrared radiation to the thermopile while blocking visible light.
