Any given FAB has hundred different types of these, and without the required tools and equipment, the FAB cannot work efficiently. One piece of equipment that drives the semiconductor fabrication process forward is lithography. There are several aspects of semiconductor fabrication that has driven by lithography equipment. Yield and defect are two such examples from the technical point of view. It is the primary reason why semiconductor fabrication focuses a lot on which type of lithography technology to deploy. Eventually, products with low yields and high defect rates will not be market-qualified. Yield: Lithography equipment plays a vital part in achieving the required target process yield. Defect: Defect free […]
