    摘要: Disclosed is a method that deposits an aqueous material having a pH between approximately 10 and 11 in a first opening and on an oxide hard mask, deposits an organic material on the aqueous material, and patterns a photoresist over the organic material. The invention then etches the organic material and the aqueous material through the photoresist to form a second opening above the first opening and forms a polymer along sidewalls of the second opening. The invention can then perform a wet cleaning process using an alkali solution having a pH between approximately 10 and 11 to remove the aqueous material from the first opening. By utilizing an alkali aqueous (water-based) material having a pH of approximately 10-11, the invention can use a fairly low pH wet etch (pH of approximately 10-11) to completely remove the aqueous solution from the via, thereby eliminating the conventional problem of having residual organic material left within the via.

    摘要: A method in which during the formation of damascene features in a semiconductor structure, a planarization material is added to vias formed in the dielectric to protect the vias during subsequent lithographic processing. The planarization material preferred is a developable photosensitive material which can be exposed and developed to define the damascene features rather than etching as is conventional.

    摘要: A method and apparatus are provided for improving the focusing of a substrate such as a wafer during the photolithography imaging procedure of a semiconductor manufacturing process. The invention is particularly useful for step-and-scan system and the CD of two features in each exposure field are measured in fields exposed at varying focus to form at least two Bossung curves. Exposure focus instructions are calculated based on the intersection point of the curves and the wafer is then scanned and imaged based on the calculated exposure focus instructions. In another aspect of the invention, when multiple wafers are being processed operational variances may cause a drift in the focus. The focus drift can be easily corrected by measuring the critical dimension of each of the features and comparing the difference to determine if any focus offset is needed to return the focus to the original calculated focus value.
