摘要： Within both a method for forming a patterned photoresist layer and a method for forming an electroplated patterned conductor layer while employing the patterned photoresist layer as a patterned photoresist plating mask layer there is first provided a substrate. There is then formed over the substrate a blanket photoresist layer formed of a negative photoresist material. There is then photoexposed the blanket photoresist layer to form a photoexposed blanket photoresist layer while employing a photoexposure apparatus which employs an annular edge ring exclusion apparatus positioned over an annular edge ring of the blanket photoresist layer and the substrate. Finally, there is then developed the photoexposed blanket photoresist layer to form a patterned photoresist layer having an annular edge ring excluded over the annular edge ring of the substrate. By employing within the context of the present invention the annular edge ring exclusion apparatus, the electroplated patterned conductor layer is formed with enhanced thickness uniformity.

摘要： A method for alignment to an alignment mark array within a patterned electronic material layer, formed on a substrate employed in a microelectronics fabrication, with improved registration accuracy of a subsequent step-and-repeat photomask pattern. There is first provided a substrate upon which is formed a patterned microelectronics layer containing an alignment mark array. There is then formed over the substrate and patterned layer, covering over the alignment marks, a subsequent layer or layers which may be of opaque material. In order to align properly a patterned photomask for patterning the overlying layer by means of conventional photolithography, the alignment mark array is located by first scanning with a laser light source contained within a step-and-repeat apparatus containing the patterned photomask and detecting the optical radiation signal scattered from the alignment mark array. The accuracy of location may be enhanced by rotating the orientation of the alignment mark array with respect to the direction of scanning with the laser light source by 90 degrees to render the subsequent orientation orthogonal to the first orientation, and then repeating the scanning operation. The altered nature of the back-scattered light signal from the orthogonal scanning direction provides additional information for improving the precision of location and alignment.

摘要： A microelectronic method is described for optimizing the fabrication of optical and semiconductor array structures for high efficiency color image formation in solid-state cameras. Disclosed is an ordered fabrication sequence in which microlens formation precedes color filter layer formation to enable increased image light collection efficiency, to encapsulate and protect the microlens elements from chemical and thermal processing damage, to minimize topographical underlayer variations which would axially misalign or otherwise aberrate microlens elements formed on non-planar surfaces, and, to complete the most difficult steps early in the process to minimize rework and scrap. A CMOS, CID, or CCD optoelectronic configuration is formed by photolithographically patterning a planar-array of photodiodes on a Silicon or other III-V, II-VI, or compound semiconductor substrate. The photodiode array is provided with metal photoshields, passivated, planarized, and, a first convex microlens array of high curvature or other suitable lenses are formed thereon. A transparent encapsulant is deposited to planarize the microlens layer and provide a spacer for the successive deposition(s) of one or more color filter layers. The microlens array may be formed from positive photoresists and the spacer from negative resist, with close attention to matching the index of refraction at layer interfaces. A final surface layer comprising a color filter completes the solid-state color image-forming device.

摘要： A new method is provided of treating the wafer prior to the process of singulating the wafer into individual die. A first surface of the wafer over which CMOS image sensor devices have been created is coated with a layer of material that is non-soluble in water. The wafer is attached to a tape by bringing a second surface of the wafer in contact with the tape. The wafer is singulated by approaching the first surface of the wafer and by sawing first through the layer of material that has been coated over the first surface of the wafer and by then sawing through the wafer, stopping at the surface of the tape. A thorough water rinse is applied to the surface of the singulated wafer, followed by a wafer clean applying specific chemicals for this purpose. The singulated die is now removed from the tape and further processed by applying steps of die mount, wire bonding, surrounding the die in a mold compound and marking the package.
