CONCAVE SPACER-WAFER APERTURES AND WAFER-LEVEL OPTICAL ELEMENTS FORMED THEREIN

摘要

Wafer-level optical elements and the concave spacer-wafer apertures in which they are formed are disclosed. The wafer-level optical elements include a spacer wafer comprising a plurality of apertures. Each aperture has a concave shape in a planar cross-section of the spacer wafer and an overflow region intersecting the planar cross-section. The wafer-level optical elements also include an array of optical elements, each optical element of the array being formed of cured flowable material within a respective one of the plurality of apertures. A portion of the cured flowable material forming each optical element extends into the overflow region of the respective aperture of the plurality of apertures. The spacer wafer includes a plurality of apertures, each of the plurality of apertures having a concave shape in a planar cross-section of the spacer wafer. Each of the plurality of apertures includes an overflow region intersecting the planar cross-section.
