Manufacture Machinery Of Silicon Wafers From Sand

how do you make silicon wafers into computer chips

To make a PC chip the layers are etched to create a pattern of lines and geometric shapes During this process the etched silicon is then exposed to a photoresist and subsequently baked again The next step in the process is to develop the photoresist Typically the process begins with the melting of silicon ingots
