WebThe Manufacturing Process of Semiconductor Thin Films The process of semiconductor manufacturing starts with a thin pure silicon wafer. Deposition places an atomic- or molecular-scale film layer over the wafer to give it the necessary electrical properties. WebThey are made out of fine carbon particles mixed with a binder (for example clay). After baking, it has a solid form. Although carbon composition resistors are widely applied in circuits, the majority of resistors today are made by deposition of a metal or carbon film over a ceramic carrier.
