摘要： A process monitoring system may detect out-of-control situations on the basis of a single criterion for a plurality of different lithography processes. To this end, each data set related to a specific type of lithography process may be processed so as to determine relative data, which may be centered around the same mean value for each of the different process types for a standard control situation.

摘要： In extremely scaled semiconductor devices, an asymmetric transistor configuration may be established on the basis of tilted implantation processes with increased resist height and/or tilt angles during tilted implantation processes by providing an asymmetric mask arrangement for masked transistor elements. For this purpose, the implantation mask may be shifted by an appropriate amount so as to enhance the overall blocking effect for the masked transistors while reducing any shadowing effect of the implantation masks for the non-masked transistors. The shift of the implantation masks may be accomplished by performing the automatic alignment procedure on the basis of “shifted” target values or by providing asymmetrically arranged photolithography masks.

摘要： A substrate support system for process tools, such as lithography tools, comprises a configuration in which a local height level adjustment may be accomplished. Thus, upon detecting a non-allowable height level, the corresponding portion of the substrate support surface may be re-adjusted. Hence, the focus conditions of advanced exposure processes may be significantly enhanced, thereby providing superior process results and also increasing tool utilization.

摘要： Mask defects, such as crystal growth defects and the like, may be efficiently detected and estimated at an early stage of their development by generating test images of the mask under consideration and inspecting the images on the basis of wafer inspection techniques in order to identify repeatedly occurring defects. In some illustrative embodiments, the exposure process for generating the mask images may be performed on the basis of different exposure parameters, such as exposure doses, in order to enhance the probability of detecting defects and also estimating the effect thereof depending on the varying exposure parameters. Consequently, increased reliability may be achieved compared to conventional direct mask inspection techniques.
