Total PDQ-WLR Solution The shortened production lifetimes of modern semicon- ductor processes have increased the importance of wafer level reliability (WLR) data. Today, wafer fabs must use WLR data from the production line to ensure the reliability of their devices. In addition, reduced reliability qualification cycle times are needed to speed new IC processes to market. Used properly, WLR can provide high quality reliability data in a few minutes that was previously obtained through weeks of reliability test done on packaged test structures. This significantly shortens the development cycle time and results in faster time to market with less cost.
