A company's success depends on the success of the company's product. In a situation where a company's product is mass-produced and may take several weeks to complete its construction, early and continual monitoring of the products' progress is essential. Such a company is Advanced Micro Devices (AMD), which manufacturers integrated circuits. Portions of AMD's monitoring efforts are performed by their Product Engineering W.E.T. analysis group. W.E.T. is an acronym for Wafer Electrical Test, and the duties of the group are to provide failure analysis of semi-conductor wafers at an individual device level. During the process of a lot, which is a cassette of up to 25 wafers, tests are routinely ran on automated probing machines, using a program called IC-MS, and the results are stored in files for further analysis. If an irregularity is observed, the wafer may require bench verification before being dispositioned to proceed with further processing. In addition to these standard inspections, Wafer Level Reliability (WLR) testing provides specific information regarding wafer processing. All these, and many more analysis procedures, allow AMD to continually improve the quality of their product.
             The investigator was given four major projects to accomplish during his tenure at Advanced Micro Devices. This would be in the form of with his exposure to WET analysis, which consists of four main projects. His first assignment was to organize a new test program using IS-MS. Second, the author was to help disposition lots that fell under a certain technology process. The next project the author was assigned was to collect and update archived WLR data, which was then organized into trend charts for comparison analysis. His fourth project was to assist in a tabulation and investigation of issues that our department is concerned with resolving. Some of these task were revoliving projects that would never be solved...
