P Type (PT/Ta/Si) 4-Inch Silicon Wafer

01 Jun 2023

 Silicon Wafer 4″ P Type 
Semiconductor memory chips are manufactured in cleanroom environments because the circuitry is so small even tiny bits of dust can damage it. Class 1 and class 10 cleanrooms are typical. In a class 1 clean room, there is no more than 1 particle of dust in a cubic foot of air. In comparison, a clean, modern hospital has about 10,000 dust particles per cubic foot. The air inside a cleanroom is filtered and recirculated continuously, and employees wear special clothing such as dust-free gowns, caps, and masks to help keep the air particle-free. which accepts Phosphorus Doped Silicon Wafer from the factory materials handling system, aligns them for processing in the etch machine, and moves them into the main part of machine.
