The project was dedicated to production yield improvement in microchip manufacturing. The bumps are created on the top of a wafer and used for the final test of all dies. Only good dies are taken for the packaging. All dies that fail the test will be scrapped. The process yield depends on the amount of "good" and "bad" dies. It was revealed that in some cases, the time between the end of the process and the final test impacts the yield. The longer the dwelling, the more dies fail the final test. If the dwelling exceeds hundreds of hours, the amount of failed dies becomes dramatically high, which results in the scrapping of the whole wafer. The problem was analyzed and solved.
Flash heating of a wafer is widely used in microchip manufacturing. The purpose of the process is to prevent the diffusion of ions and atoms. During the flash process, a wafer breakage occurs. The project's purpose is to learn and understand the mechanism of the wafer breakage and propose the solutions to prevent the wafer breakage
An example of how to make task prioritization with Urgency - Important Matrix (UMI) using the PRIZ Innovation Platform
The vacuum cleaner problem is an excellent example showing how to manage and resolve excursion - unexpected deviation from normal operation. Read, learn and use the platform for resolving of your excursions.
The vacuum furnace is used for sintering parts made of metal powder. To keep the shape of the parts, a binder is used. The main problem is that the vacuum furnace becomes dirty and needs a very long cleaning. Regular washing was not successful. We investigated the process and found that washing should be dedicated to the conversion of the material into a form that results in the formation of gases having low temperature of the condensation
