There is a voltage stabilizing device in the yellow light area, so that the wafer will not be scrapped, but the yellow light of the semiconductor will cause the risk of film, diffusion and etching area, which is so great that it can be said that it is completely scrapped.
Yellow light is the process of gluing, soft baking, exposure, development and hard baking silicon wafers in the semiconductor industry, so that they can be photoetched into certain patterns. The characteristic is that yellow light is one of the manufacturing processes of fine circuits.
