Wafer-Level Array Cameras And Methods For Fabricating The Same

摘要

A wafer-level array camera includes (i) an image sensor wafer including an image sensor array, (ii) a spacer disposed on the image sensor wafer, and (iii) a lens wafer disposed on the spacer, wherein the lens wafer includes a lens array. A method for fabricating a plurality of wafer-level array cameras includes (i) disposing a lens wafer, including a plurality of lens arrays, on an image sensor wafer, including a plurality of image sensor arrays, to form a composite wafer and (ii) dicing the composite wafer to form the plurality of wafer-level array cameras, wherein each of the plurality of wafer-level array cameras includes a respective one of the plurality of lens arrays and a respective one of the plurality of image sensor arrays.

1. A wafer-level array camera, comprising:
an image sensor wafer including a M×N image sensor array, M and N are positive integers; a spacer disposed on the image sensor wafer; and a lens wafer disposed on the spacer, the lens wafer including a M×N lens array, each lens of the lens wafer having the same back focal length and being disposed at the same distance from a respective image sensor of the image sensor wafer.
