Abstract
The concept of Cpk has been a long accepted method for indicating manufacturing process capability and making critical judgments about expected performance. Within this paper Cpk's are calculated for a set of test masks generated by divergent photomask lithography tools. The MSTM (Manufacturing Simulation Test Mask) uses different address sizes (1.0, 0.5, 0.25, and 0.1 micrometers ) allowing all address structures to be tested on the same mask. A Leica LMS- 2000 was used for the registration measurements. Through critical observation of the data sets' mean and range variance, an insight about contributing error sources is gained and a common ground for unbiased comparison is found.
