ABSTRACT:
A method of fabricating a slant reflector with a bump structure, includes the steps of: providing a substrate; forming a layer of photosensitive material on the substrate; patterning the photosensitive material to form a plurality of trapezoidal bumps that have different bottom areas and that are joined to each other at their bottoms; and smoothing the trapezoidal bumps to form a bump structure with an inclined angle. The invention utilizes a photo-mask with a particular pattern and optical diffraction to fabricate the bump structure in a simple way.
