    摘要： One embodiment relates to a method for semiconductor workpiece processing. In this method, a baseline tool induced shift (TIS) is measured by performing a baseline number of TIS measurements on a first semiconductor workpiece. After the baseline TIS has been determined, the method determines a subsequent TIS based on a subsequent number of TIS measurements taken on a first subsequent semiconductor workpiece. The subsequent number of TIS measurements is less than the baseline number of TIS measurements.

    摘要： The present disclosure relates to a lithographic tool arrangement for semiconductor workpiece processing. The lithographic tool arrangement groups lithographic tools into clusters, and selectively transfers a semiconductor workpiece between a plurality of lithographic tools of a first type in a first cluster to a plurality of lithographic tools of a second type in a second cluster. The selective transfer is achieved though a transfer assembly, which is coupled to a defect scan tool that identifies defects generated in the lithographic tool of the first type. The disclosed lithographic tool arrangement also utilizes shared structural elements such as a housing assembly, and shared functional elements such as gases and chemicals. The lithographic tool arrangement may consist of baking, coating, exposure, and development units configured to provide a modularization of these various components in order to optimize throughput and efficiency for a given lithographic fabrication process.

    摘要： A patterned silicon nitride layer formed over a semiconductor integrated circuit wafer having a layer of pad oxide is often used as a mask for subsequent processing steps. Etching of the silicon nitride layer is difficult to control and can create defects in the pad oxide layer which are difficult to detect before the manufacture of the semiconductor integrated circuit wafer is completed. A method is described using potassium hydroxide treatment and scanning electron microscope evaluation of a test wafer for detection of defects at the silicon nitride etching step. Continued processing of defective wafers can be terminated and the silicon nitride etching step can be controlled using this method.
