Latest Patents

Andrew Bessy holds a patent for a "Static Resistant Reticle." This invention is designed for use in photolithography and features optimal transmission while reducing electrostatic discharge. The reticle consists of a substrate, a patterning layer, and two layers of materials with differing refractive indices. The first layer has a higher refractive index than the second, and at least one of these layers is conductive. This design allows for an anti-reflective coating that optimizes light transmission through the reticle substrate to approximately 98.0% to 99.5% at wavelengths between 360 nm and 370 nm. The conductivity of the layers further minimizes electrostatic discharge, improving the delineation of patterns projected onto silicon wafers used in semiconductor devices. The preferred materials for the layers include ruthenium oxide and silica.
