The invention of the integrated circuit is one of the great achievements of the 20th century. There are hundreds of new integrated circuit tests and production every year. Now the international mainstream silicon diameter is 8 inches, and if only one integrated circuit is tried on the same silicon, the cost of the test is extremely high. Multi-project wafer manufacturing is made on the same wafer in the same wafer in multiple processes, so that expensive platelets and wafer processing costs are shared by multiple shares (if 30 projects are machined, the cost is only the original number 1/30), thereby greatly reduces the cost of experimental manufacturing, as shown in the following figure. The United States called this service as MOSIS (Metal-Oxide-Semiconductor-Implement Service), which is called CMP (Circuit Multi-Projects), which is provided by CMC (Canadian Microelectronics Corporation).
Multi Project Wafer, Abbreviation MPW) is to design a plurality of integrated circuits using the same process on the same wafer on the same wafer, after the manufacturing is completed, each design can get dozens of chip samples, this amount The test is sufficient for experiments in the prototype design phase. The manufacturing cost is shared by all the MPW projects, which is only 5% -10% of the cost of prototype manufacturing costs, which greatly reduces product development risks, and cultivates the threshold and small and medium integration of integrated circuit design talents. Circuit design business at the beginning of the start.
For economic reasons, Foundry is more inclined to receive large wafer processing services, and multi-project wafers provide effective ways for small batch production.
