A COMPANIES SUCCESS
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.
igator 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 and others were put with time constraints whereas the author might have some difficultiy accomplishing. The projects mentioned above are not ones that are necessarily completed, but are continually worked on as needs arise. All of these projects relate to one or more of the other projects and help gain a better understanding of the others. Together they provide an adequate, but brief overview of WET. Advanced Micro Devices is a living and breathing learning envirorment. It is hardly possible to complete any task without learning something new. The author would learn that the three easiest way to learn more about any process or tool in the company would be to take a class, visit the library, or view the department references. Advanced Micro Devices offered classes on nearly anything that could relate to any persons job. Also employees were encouraged to take advantage of these free courses and were allowed to enroll in courses not related to their job title. The company also had an onsite library. The books here could be sat down and read or checked out on a person's badge. This would prove useful in the authors programming endeavors. Each department also had references. These were a collection of books and manuals left or contributed by current or former employees. These references would provide direct pertanance to issues the author faced. The three major sections of test definition are:
