Beschreibung
Silicon metal powder is a fine-grained form of silicon that is used in a variety of industries, including the electronics industry. It is used as a raw material in the production of semiconductor devices like transistors. Silicon metal powder is also used as an alloying element, where it is mixed with other metals to improve their properties.

Once the pattern is etched onto the wafer, a layer of silicon oxide is grown on top of the wafer. This oxide layer acts as a barrier between the different layers of the transistor, preventing them from short-circuiting. The oxide layer is then patterned, and a layer of metal is deposited on top of it. This layer of metal forms the contacts that connect the transistor to the rest of the circuit.
A: From raw materials' selecting, smelting, crushing, finished products' testing, packing, to pre-shipment inspecting, every step, Zhenan people are all implementing strict quality control.
