Abstract
In one embodiment, a system is disclosed that includes an illuminator having a source that produces light waves having a first wavelength, and a mask. The mask includes at least one partly opaque area and at least one opening within the opaque area includes a slanted, sub-resolution feature that redistributes a portion of the light passing through the open area to an off-axis location. A method of forming a device by way of photolithography might include forming unresolvable features on a mask and projecting light through the mask. Other systems, methods, and apparatus are disclosed.
