Abstract: A multi-aperture irradiation profile shaping system is presented that uses at least one arrangement of at least three apertures associated with a plurality of optical elements, wherein at least one optical element has positive optical power and another one element has negative optical power. The system may be implemented with the apertures in one, two, or three dimensions. The system yields a predetermined arbitrary irradiation profile on a target. The shape of the apertures may be any one of square, rectangular, and hexagonal. The shape of the apertures may also be asymmetric so that a rotation of the aperture shape by 180 degrees around an axis perpendicular to the surface of the aperture yields an inverted aperture shape. The system may be implemented with apertures having symmetric and asymmetric shapes that allow nearly 100% fill factor.

Abstract: A projection eyepiece and method for aligning pattern areas on a substrate surface having a micro-optical device on an opposite surface side of the substrate is disclosed. The projection eyepiece enables projection of a reticle image onto a first surface of a substrate, enabling receipt of a reflection of that reticle image from a micro-optical device located on a second and opposing surface of the substrate, and enabling comparison of the projected and received image to determine alignment of the point of incidence on the first surface with the micro-optical device of the second surface. The projection eyepiece therefore determines alignment of pattern areas on opposing substrate surfaces by comparing a projected reticle image to a reflection of that projected reticle image.

Abstract: A structure and method for circularizing and collimating incident light involves a substrate having first and second opposing surfaces, a first anamorphic surface positioned on the first surface and a second anamorphic microlens positioned on the second surface, the first and second surfaces being separated by a distance defined by the distance required for the first anamorphic microlens to circularize the incident light. A single microlens structure used to circularize and collimate incident light is manufactured by identifying aligned portions on opposing surfaces of a substrate, and forming microlenses on each of the aligned portions of the opposing substrate surfaces identified. The microlenses formed on the opposing substrate surfaces are fabricated from a high-index material such as GaP.

Abstract: A system and method for achieving alignment of a mask and substrate focuses a first image (e.g., a reticle) on a first position of a first substrate surface, and determines whether the first position is aligned with a second position on an opposing second substrate surface based on a second image formed based on light from a micro-optical device located on the second surface which collects light from a first image focused thereon. To determine whether the first and second positions are aligned, the first image and the second image are projected on an image plane and compared, the first and second positions being aligned when the first image and the second image are coincident on the image plane. A mask and/or alignment pattern may be formed on the opposing substrate surfaces, and used to generate aligned optics on those surfaces. As such, precise alignment between optics on opposing surfaces of a substrate can be achieved.
