The Applied Materials AMC 7821 EPI is an epitaxial silicon deposition system. The AMC 7821 EPI processes 6-inch wafers.[1][2][3]
What it is
How it works
General reference — not yet source-verifiedEpitaxial deposition systems operate by chemical vapor deposition at high temperature. A silicon-containing precursor gas, such as silane or dichlorosilane, is introduced into a reaction chamber with a hydrogen carrier gas. The gas decomposes on the heated wafer surface, depositing a single-crystal silicon layer that replicates the crystal orientation of the underlying wafer.
Where it fits in the process flow
General reference — not yet source-verifiedEpitaxial deposition typically follows wafer cleaning and precedes further processing steps such as lithography, etching, and doping. The epitaxial layer serves as the active region for many semiconductor devices, providing a high-quality crystalline surface with controlled resistivity.
Applications
General reference — not yet source-verifiedEpitaxial layers enable precise control of doping concentration and layer thickness, which is critical for high-performance and power devices. The system can also be used for epitaxial growth on patterned wafers in the fabrication of advanced device structures.
