Abstract: Method for reducing resist poisoning. The method includes the steps of forming a first structure in a dielectric on a substrate, reducing amine related contaminants from the dielectric and the substrate prior to a formation of a second structure on the substrate such that the amine related contaminates will not diffuse out from either the substrate or the dielectric, wherein the reducing utilizes a plasma treatment which one of chemically ties up the amine related contaminates and binds, traps, or consumes the amine related contaminates during subsequent processing steps, forming the second structure on the substrate, and after the forming of the first structure, preventing poisoning of a resist layer in subsequent processing by the reducing.

Abstract: Photolithography tools have alignment systems for aligning a level to be printed with a level already on the wafer. Commonly a photolithography tool has several alignment systems Also, wafers may have several alignment marks, and the various alignment systems may be capable of reading several of the alignment marks. The present invention provides a method of selecting the alignment system-alignment mark combination that gives the most accurate alignment to a previous level. The inventors found that residual errors provide a metric by which to evaluate alignment system-alignment mark combinations. The combination with the least residual error is selected. Alternatively data for actual overlay measurements is compared with alignment data for each alignment system-alignment mark combination, and the combination that has the best correlation to the overlay data is selected.

Abstract: A method of fabricating an attenuating phase shift photolithographic mask which will reduce the formation of side-lobes adjacent to large structures in the kerf regions on the patterned wafer. These structures are typically much larger in size than device nominal, and this method may be applied to either one axis or both axes of the kerf structure depending on it's susceptibility to form side-lobes. A substantially defect free optical lithography mask having partially transmissive attenuating phase-shift regions, transmissive clear regions, and more opaque than partially transmissive regions is fabricated by first depositing an attenuating phase-shifting layer on the top surface of a transmissive substrate followed by deposition of a more opaque than partially transmissive layer on top of the partially transmissive attenuating phase-shifting layer. Next an image transfer layer is deposited on top of the more opaque than partially transmissive layer.

Abstract: In a plasma or RIE etching tool using a uniquely designed annulus around a wafer supporting pedestal, it has been found that the introduction of one or more gases in the region immediately adjacent the annulus controls the amount of etching of features in that region in the surface of the wafer mounted on the pedestal. By so controlling the amount of gas in this region, the slope of the walls of the etched features can be also controlled.
