  • Patent number: 11996397
    Abstract: Wafer level proximity sensors are formed by processing a silicon substrate wafer and a silicon cap wafer separately, bonding the cap wafer to the substrate wafer, forming an interconnect structure of through-silicon vias within the substrate, and singulating the bonded wafers to yield individually packaged sensors. The wafer level proximity sensor is smaller than a conventional proximity sensor and can be manufactured using a shorter fabrication process at a lower cost. The proximity sensors are coupled to external components by a signal path that includes the through-silicon vias and a ball grid array formed on a lower surface of the silicon substrate. The design of the wafer level proximity sensor passes more light from the light emitter and more light to the light sensor.
