Latest Patents

Osborne holds a patent for "Laser planarization of nonrefractory metal during integrated circuit." This invention involves the use of optical pulses from a laser, such as a xenon chloride excimer laser, to momentarily melt nonrefractory micrometer-thick deposited metals, like aluminum and aluminum alloy films, on integrated circuits. The process enhances the reflow of the metal upon melting by preheating the substrate and any intervening dielectric and conductive layers to approximately one-half the melting temperature of the metal. This technique improves planarization and reduces stress in the resolidified metal, making it an attractive method for fabricating multilayer interconnect structures.
