In some embodiments, more lenses may be produced than will eventually be used by the lasers. The inner portion of the substrate may be formed with the lenses that will be used for emitting lasers, and the outer portion of the substrate may be formed with lenses that will not be used for emitting lasers—rather, through etching these additional lenses, the inner lenses may be created with a higher quality. 1. A method for manufacturing lenses , the method comprising:etching a layer of photoresist over a substrate to form a lens array with a plurality of lenses, wherein the lens array further comprises an inner portion with a first set of lenses and an outer portion with a second set of lenses, wherein the second set of lenses is positioned adjacent to and surrounds the first set of lenses, wherein each lens in the first set of lenses is surrounded by a same number of lenses of either the first set of lenses or the second set of lenses; andpositioning each laser among a plurality of lasers to correspond with each lens in the first set of lenses and positioning no laser to correspond with any of the lenses in the second set of lenses.2. The method of claim 1 , wherein etching the layer of photoresist is accomplished by at least one of: a wet etching process claim 1 , an anisotropic wet etching process claim 1 , a plasma etching process claim 1 , and a dry etching process.3. The method of claim 2 , wherein etching a layer includes transferring a pattern for the lens array from photoresist into the substrate.4. The method of claim 1 , wherein the lens array is circular in configuration.5. The method of claim 1 , wherein the plurality of lasers are positioned on the opposite side ...

A method of fabricating a multi-tone amplitude photomask includes providing a mask substrate. The method includes providing a stepped pattern in at least one layer of material on a surface of the mask substrate. The stepped pattern includes at least two steps and at least three levels. Each level of the stepped pattern provides a different intensity of light when a light source shines light on the stepped pattern. 1. A method of fabricating a multi-tone amplitude photomask , comprisinga. providing a mask substrate; andb. providing a stepped pattern in at least one layer of material on a surface of said mask substrate, wherein said stepped pattern includes at least two steps and at least three levels, wherein each level of said stepped pattern provides a different intensity of light when a light source shines light on said stepped pattern.2. A method as recited in claim 1 , wherein said providing a stepped pattern in said at least one layer of material on said surface of said mask substrate includes providing a layer of a polymer on said mask substrate and ablating or etching said layer of polymer to form a pattern in said polymer wherein said pattern in said polymer includes a first portion having a first thickness and a second portion having a second thickness.3. A method as recited in claim 2 , wherein said ablating includes laser ablating with a scanning laser.4. A method as recited in claim 2 , wherein said ablating includes ablating with a holographic mask.5. A method as recited in claim 2 , wherein said etching includes plasma etching or reactive ion etching through a mask.6. A method as recited in claim 1 , wherein said providing a stepped pattern in at least one layer of material on a surface of a mask substrate includes additively providing patterned layers of polymer on said mask substrate to provide said stepped pattern.7. A method as recited in claim 1 , wherein said providing a stepped pattern in at least one layer of material on a surface of a mask ...
