⚙️ Equipment Function / Features
The ultra-high-vacuum electron beam evaporation system adopts a linear multi-chamber design (load-lock chamber + deposition chamber + oxidation chamber). It supports metal film deposition, ion beam etching, and oxidation processes. With its high-vacuum transfer system enabling continuous processing, it provides highly directional and precise deposition for nanoscale structures—ideal for high-density integrated circuits and quantum device fabrication.
