Electron Beam Vacuum Evaporation Equipment

This Electron Beam Vacuum Evaporation System executes physical vapor deposition (PVD) of high-melting-point metals, oxides, and dielectrics. By directing a focused electron beam into a water-cooled copper hearth, the system delivers localized temperatures up to 3000°C while keeping chamber walls cool, preventing crucible interaction and preserving film purity.

Designed for cleanroom R&D and industrial production, the architecture integrates a high-vacuum chamber, multi-pocket electron gun, programmable beam deflection, and real-time film thickness monitoring.

270° Magnetic Deflection: Curves the electron beam to position the emitter filament away from the evaporation plume, eliminating filament degradation and extending run-time.

Programmable Beam Sweep: Microprocessor-controlled coils distribute energy across the evaporant surface, suppressing cratering, nodule formation, and spitting.

Interlocked Cooling Matrix: Thermal sensors and flow switches monitor crucibles, pumps, and power supplies, triggering automated halts if thresholds are exceeded.

Roughing Train: Oil-free roots blowers and multi-stage dry screw pumps establish baseline vacuum without hydrocarbon backstreaming.

High-Vacuum Train: Cryogenic pumps paired with pneumatic gate valves deliver rapid pumping speeds for water vapor and process gases.

Instrumentation: Pirani and hot-cathode ionization gauges link directly to the PLC safety interlock matrix.
