    摘要: A system for removing excess material from a semiconductor wafer employs an excimer laser for ablative photocomposition. A wafer is positioned on an X-Y stage that is computer controlled to position the wafer at points where the laser may be focused to remove excess material whether over alignment marks or identified contamination. The laser passes through a vacuum chamber which by generating an inward laminar flow constrains any particulate contamination resulting from the ablative photodecomposition from spreading. This material is removed by the vacuum system.

    摘要: The present invention provides a method for determining the development endpoint in a X-ray lithographic process. Endpoint is determined by visually observing resist test field patterns through a microscope during the developing step. During the developing, changing test field patterns are formed because test field locations each had been exposed simultaneously to different radiation doses. These different doses are produced when radiation passes through a mask containing a plurality of different size radiation attenuators. When the changing test field pattern matches a known pattern, which is correlated to the desired development endpoint, the workpiece is removed from the developing step.

    摘要: A high-performance radiation sensitive silicon-containing negative-tone resist is provided along with a method of using the silicon-containing resist in multilayer, including bilayer, imaging for manufacturing semiconductor devices. The negative-tone silicon-containing resist is based on an acid catalyzed high-contrast crosslinking of aqueous base soluble silicon-containing phenolic polymers through reaction of a carbocation of the crosslinking agent with the hydroxyl site of the phenolic group in the silicon-containing polymers. A chemically amplified silicon-containing negative-tone resist composition comprising said silicon-containing polymer resin; at least one crosslinking agent; one acid generator; and a solvent is provided. The silicon-containing resist composition has high silicon content and provide excellent resolution and a means of patterning high aspect ratio resist patterns. The resist compositions can be used as the top imaging layer in a multilayer, including bilayer, scheme to fabricate semiconductor devices using various irradiation sources, such as mid-ultraviolet (UV), deep-UV, extreme UV, X-ray, e-beam and ion-beam irradiation.
