5 Stages Of IC Fabrication, You Will Be Amazed at Knowing!
An integrated Circuit – IC, is the term that even every kid is aware of! The IC fabrication itself an interesting process to explore about. Imagine an IC which can’t be viewed with a naked eye and requires a microscope for, then what would be its manufacturing process like? Do you know an IC incorporates millions of components within? These components are transistors, capacitors, diodes etc. Let’s have a glance at a bunch of processes towards semiconductor fabrication . 1. Wafer Production Only wafer production consists of series of processes one after another. Firstly, silicon, fetched from sand, is heated to form a liquid. Silicon’s small piece is dipped in this liquid and then taken out to cool. With the use of wafer slicing machine, it’s cut into thin wafers with a thickness around 0.1 to 0.25 inches. After that, it passes through the process of polishing and cleansing followed by exposure to ultra pure oxygen. 2. Masking Masking is an essential part of IC
