Silicon wafer manufacturing process ppt

The first step in the wafer manufacturing process is the formation of a large, perfect silicon crystal. The crystal is grown from a 'seed crystal' that is a perfect crystal. The silicon is supplied in granular powder form, then melted in a crucible. The seed is immersed carefully into the crucible of molten silicon, then slowly withdrawn

2020-4-23  Wafer products are measured at various stages of the process to identify defects inducted by the manufacturing process. This is done to eliminate unsatisfactory wafer materials from the process stream and to sort the wafers into batches of uniform thickness and at a final inspection stage. These wafers will become the basic raw material for new integrated circuits. The following is a summary of the steps in a typical wafer manufacturing
