PVD Multi-Process Thin Film Equipment

The PVD Multi-Process Thin Film Equipment is an integrated vacuum deposition platform engineered to combine multiple thin-film fabrication techniques-including RF/DC Magnetron Sputtering, Thermal Evaporation, and Electron Beam Evaporation-within a unified vacuum architecture.

This system eliminates vacuum break contamination between distinct process layers, enabling the deposition of complex multi-layer metallic, dielectric, and semiconductor films without ambient exposure. Configured for laboratory R&D clusters or pilot-line production, it accommodates substrates up to 300mm in diameter or customized carriers.

Modular Vacuum Architecture: Independent process chambers coupled via gate valves prevent cross-contamination between reactive sputtering and high-vacuum evaporation.

In-Vacuum Substrate Transfer: Magnetic or linear transfer arms maintain high vacuum (< 10^-4 Pa) during inter-chamber sample movement.

Quick-Change Source Flanges: Sputter cathodes and e-beam crucibles are mounted on standard CF flanges for rapid maintenance and target replacement.

Advanced Cryogenic Trapping: Integrated liquid nitrogen cold traps and Meissner traps minimize residual water vapor pressure inside the chamber.

Closed-Loop Thickness Monitoring: Dual quartz crystal microbalance (QCM) sensors provide real-time deposition rate and thickness feedback linked directly to power supply regulation.

Roughing Stage: Oil-free scroll pumps paired with multi-stage roots blowers to eliminate hydrocarbon back-streaming.

High Vacuum Stage: Backed by magnetically levitated turbo-molecular pumps (> 1200 L/s for N2) and optional cryopumps for high water-vapor throughput.

Pressure Regulation: Baratron capacitance manometers for absolute pressure measurement independent of gas species, paired with automated throttle valves for precise process gas pressure control (0.1 Pa to 10 Pa).

Leak Detection: Helium leak-tested to < 1 x 10^-9 Pa*m^3/s prior to factory acceptance testing (FAT).

Conductive Targets: Au, Ag, Cu, Al, Ti, Cr, ITO, AZO, Mo, W, NiCr.

Dielectric Materials: SiO2, TiO2, Al2O3, Ta2O5, HfO2 (via reactive sputtering or e-beam).

Substrate Types:
Semiconductor wafers (Silicon, Gallium Arsenide, Indium Phosphide).

Optical blanks (Fused silica, BK7, Sapphire).

Flexible webs and thin metal sheets (Polyimide, stainless steel foil).

Optoelectronics: Deposition of transparent conductive oxide (TCO) layers and anti-reflective (AR) optical filter stacks.

Semiconductor Device Fabrication: Formation of ohmic contacts, Schottky barriers, seed layers for electroplating, and diffusion barriers (Ti/TiN).

Sensor Manufacturing: Thin-film metallic strain gauges, micro-heater elements, and piezoelectric transducers.

Advanced R&D: Exploratory multi-layer thin-film synthesis for quantum computing components and novel energy storage materials.

Chamber Geometry: Expanding chamber dimensions for non-standard or oversized batch substrates.

Source Integration: Custom allocation ratios between magnetron sputtering guns and electron beam evaporation pockets.

Bias Sputtering: Substrate RF/DC biasing options for film densification and stress control.

Load-Lock Integration: Addition of automated load-lock chambers to maintain high vacuum integrity during high-throughput loading cycles.

Material Traceability: Mill test certificates (MTCs) provided for all vacuum-side stainless steel components and structural frames.

Cleanroom Assembly: Final integration and particle-count verification performed in an ISO Class 6 cleanroom environment.

Factory Acceptance Testing (FAT): 72-hour continuous vacuum bake-out test, leak testing via residual gas analyzer (RGA) mass spectrometry, and baseline film deposition run verifying thickness uniformity.

Site Preparation Guide: Comprehensive utility mapping provided pre-shipment, detailing chilled water flow rates (> 15 L/min), compressed air, process gas lines (Ar, O2, N2 at 99.999% purity), and electrical load requirements (3-phase 380V/480V).

Commissioning: On-site installation, vacuum calibration, and joint test-runs conducted by factory field service engineers.

Operator Training: Structured 5-day on-site training covering routine maintenance, vacuum safety protocols, recipe programming, and basic troubleshooting.
