摘要： The present invention relates to an image sensor comprising a microlens array, and to a manufacturing method thereof. The method of the present invention includes gradually increasing the aluminum composition ratio of a compound semiconductor as the latter gradually gets farther from a substrate, to enable a microlens-forming layer to grow, and making the oxidation rate of the region adjacent to the substrate slower and the oxidation rate of the region farther from the substrate faster, making the interface between the oxidized region and the unoxidized region into a lens shape after the completion of oxidation. The thus-made lens is integrated into an image sensor. The present invention reduces costs for manufacturing image sensors in which a microlens is integrated, increases the signal-to-noise ratio and resolution of the image sensor, and achieves improved sensitivity.

摘要： Surface measurement data just provides the coordinates of an object surface without giving various parameters like the radius of curvature, conic constant, and deformation coefficients. In this paper, we propose a novel method for extracting the important parameters for the determination of unknown aspheric surface equations from the measurement of aspheric surfaces. The largest error between the original surface and the reconstructed surface in the theoretical case is shown to be about 8.6 nm. This fact implies that the new method is well suited for the reconstruction of unknown surface equations.
