Image-sensor chip-scale package and method for manufacture

Abstract

A method for fabricating an image-sensor chip-scale package includes bonding, with temporary adhesive, a glass wafer to a device wafer including an array of image sensors. The method also includes forming an isolated-die wafer by removing, from the device wafer, each of a plurality of inter-sensor regions each located between a respective pair of image sensors of the array of image sensors. The isolated-die wafer includes a plurality of image-sensor dies each including a respective image sensor, of the array of image sensors, bonded to the glass wafer. The method also includes encapsulating the isolated-die wafer to form an encapsulated-die wafer; removing, from each of the plurality of image-sensor dies, a respective region of the glass wafer covering the respective image sensor; and singulating the encapsulated-die wafer.
