摘要:
Methods of forming microlens structure are provided. A hard mask is formed overlying a transparent material. An opening is patterned into the hard mask. Both the patterned hard mask and the underlying transparent material are exposed to a wet etch that etches the hard mask and the transparent material. As the hard mask is etched the opening increases exposing more of the transparent material. Depending on the etch selectivity, a lens shape is formed with sloped sidewalls. The lens opening may be filled with lens material to form a lens.

摘要:
A sub-resolutional grayscale reticle and associated fabrication method have been presented. The method provides a transparent substrate, and forms a plurality of coincident partial-light transmissive layers overlying the transparent substrate. A pattern is formed, sub-resolutional at a first wavelength, in at least one of the transmissive layers. If there are n transmissive layers, the reticle transmits at least (n+1) intensities of light. In one aspect, each of the plurality of transmissive layers has the same extinction coefficient and the same thickness. In other aspects, the transmissive layers may have different thickness. Then, even if the extinction coefficients are the same, the attenuation of light through each layer is different. The transmission characteristics of the reticle can be further varied if the transmissive layers have different extinction coefficients. Likewise, the transmission characteristics through the sub-resolutional patterns can be varied.
