Abstract
A method for forming a lens barrel includes aligning each of a plurality of upper apertures of an upper wafer to (i) a respective one of a plurality of middle apertures of a middle wafer and (ii) a respective one of a plurality of lower apertures of a lower wafer. The middle wafer is between the upper wafer and the lower wafer. The method also includes bonding the middle wafer to the upper wafer to form a lens barrel wafer. Each triad of co-aligned upper, middle, and lower apertures forms a wafer aperture spanning between a top surface of the upper wafer and a bottom surface of the lower wafer. Each upper aperture has a respective upper width and each middle aperture has a respective middle width less than the respective upper width to form, in each triad, a ledge for supporting a lens in the upper aperture.
