    摘要: The present invention relates to a method of accessing and repairing electrical opens in conducting metal lines on a semiconductor chip or other substrate using a thin conductive layer formed within the surface of a substrate and laser plating techniques. What has been described is a maskless means of repairing discontinuities in a conductor disposed on the surface of a substrate wherein the surface is locally irradiated to form a reversible carbonaceous layer thereon. This reversible carbonaceous layer acts as a base for electrodeless deposition of a metal to form a bridge across the discontinuity by laser-enhanced exchange plating or other suitable methods. Further, a means of accessing and repairing a discontinuity buried by a cover layer of an insulating or passivating material is described, wherein access to the discontinuity is provided by ablating away the cover layer using a pulsed excimer laser at a first power level.

    摘要: A static resistant reticle for use in photolithography having optimal transmission and reduced electrostatic discharge. The reticle comprises a substrate, a patterning layer, and two layers of material having a first refractive index and a second refractive index wherein the first refractive index is greater than the second refractive index and at least one of the layers is conductive. The refractive indices and thickness of the layers are matched to create an anti-reflective coating. The anti-reflective coating optimizes transmission of light through the reticle substrate to about 98.0% to about 99.5% at a wavelength of about 360 nm to about 370 nm. The conductivity of at least one of the layers reduces electrostatic discharge further improving delineation of the pattern projected onto a silicon wafer of a semiconductor device. Preferably, the anti-reflective coating comprises two or more layers of cermet material. The layer of material having a first refractive index is most preferably ruthenium oxide or ruthenium oxide with alumina. The second layer of material having a second refractive index is most preferably silica. A method of fabricating a static resistant reticle, and a method of patterning a silicon wafer using the reticle of the present invention is also described.
