Angstrom Engineering Box-Type PVD Coater

Overview

The Angstrom Engineering Box-Type PVD Coater is a modular, high-precision physical vapor deposition system engineered for research and pilot-scale thin-film fabrication in microelectronics and advanced materials development. Unlike roll-to-roll or inline production tools, this batch-type coater employs a static chamber architecture optimized for reproducible, multi-layer deposition under precisely controlled vacuum, thermal, and plasma environments. Its core operation relies on well-established PVD principles—including thermal evaporation (resistive or e-beam), magnetron sputtering (DC, RF, or reactive), and optional pulsed laser deposition—enabling atomic-level control over film stoichiometry, thickness uniformity (<±2% across 100 mm substrates), and interfacial integrity. Designed for cleanroom-integrated labs and university nanofabrication facilities, the system supports substrate sizes from 100 mm wafers up to 1200 mm × 1200 mm planar samples, with configurable electrode geometries, shutter sequencing, and in-situ monitoring interfaces (e.g., quartz crystal microbalance, optical emission spectroscopy ports).

Key Features

• Modular vacuum chamber design with front-loading or top-loading configurations, compatible with ISO-KF and CF flange standards for rapid tooling reconfiguration.
• Integrated turbomolecular pumping stack backed by dry scroll or cryogenic pumps, enabling base pressures down to 1×10⁻⁹ Torr in UHV-capable variants—critical for oxide-sensitive depositions (e.g., SrTiO₃, YBCO) and low-defect metal films.
• Multi-source capability: Simultaneous or sequential operation of up to four independent PVD sources (e.g., dual e-beam crucibles + dual magnetron targets), each with programmable power ramping and real-time power feedback.
• Substrate heating stage with PID-controlled temperature range from RT to 800°C (±1°C stability), coupled with optional liquid nitrogen cooling for cryogenic deposition studies.
• Programmable motion control: Motorized substrate rotation (0–30 rpm), vertical lift (for shadow masking), and planetary rotation for enhanced thickness uniformity on non-planar or large-area substrates.
• Full integration with Angstrom’s proprietary CoatOS control platform—supporting deterministic recipe management, hardware interlocking, and audit-trail logging compliant with GLP and internal QA protocols.

Sample Compatibility & Compliance

The Box-Type PVD Coater accommodates rigid and semi-rigid substrates including silicon wafers (100–300 mm), fused silica, sapphire, glass slides, ceramic tiles, and flexible metallic foils (e.g., Ni alloy, Mo foil). It supports deposition onto temperature-sensitive polymer substrates (e.g., PI, PET) via low-power e-beam or cold sputtering modes. All vacuum components conform to ASTM F2759-22 (Standard Guide for Vacuum System Integrity Testing) and ISO 20483-2 (Vacuum Technology — Vocabulary). The system meets CE Machinery Directive 2006/42/EC requirements and includes integrated safety interlocks per IEC 61508 SIL2 for vacuum breach, overtemperature, and high-voltage fault conditions. Optional FDA 21 CFR Part 11-compliant software modules are available for regulated environments requiring electronic signature, user role-based access, and immutable audit trails.

Software & Data Management

CoatOS v5.2 provides a deterministic, script-driven interface for process replication and cross-system portability. Each deposition run generates timestamped metadata logs—including source power profiles, chamber pressure transients, substrate temperature history, and QCM thickness accumulation—exportable in CSV, HDF5, or MDF4 formats. Real-time data streaming supports integration with LabVIEW, Python (via PySerial/PyVISA), or MATLAB for closed-loop optimization. Recipe versioning, parameter locking, and change history tracking ensure traceability from R&D through qualification. For shared-facility use, multi-user authentication (LDAP/Active Directory support) and session-based resource scheduling prevent configuration conflicts and enforce usage accountability.

Applications

This system serves critical functions across semiconductor process development (e.g., Al/TiN gate stacks, TaN diffusion barriers), photonic device fabrication (ITO/Ag/ITO transparent electrodes, SiNₓ anti-reflection coatings), quantum material synthesis (NbN superconducting films, CrI₃ van der Waals heterostructures), and MEMS packaging (AlN piezoelectric layers, TiW adhesion promoters). Its flexibility in source selection and chamber environment control makes it equally suitable for developing barrier layers for flexible OLEDs, seed layers for electroplating, or functionalized surfaces for biosensor platforms. Academic users leverage its open architecture for fundamental studies in nucleation kinetics, stress evolution during growth, and interdiffusion at multilayer interfaces.

FAQ

What vacuum level can be achieved with the standard configuration?
Standard systems achieve ≤5×10⁻⁸ Torr base pressure using a 700 L/s turbomolecular pump and dry backing pump; UHV options reach ≤1×10⁻⁹ Torr with cryo-pumping and all-metal sealing.
Is remote operation supported?
Yes—CoatOS supports secure remote monitoring and limited intervention via TLS-encrypted web interface or VNC, with configurable access permissions per user group.
Can the system be upgraded with in-situ ellipsometry or XRD?
Chamber ports comply with ConFlat 63.5 mm (2.5″) and larger diameters, permitting integration of commercial in-situ optical probes or grazing-incidence XRD stages without structural modification.
What maintenance intervals are recommended for the e-beam source?
E-beam crucible assemblies require visual inspection every 200 hours of operation; filament replacement is typically scheduled every 500–800 hours depending on evaporation rate and material purity.
Does Angstrom provide installation and training services?
Yes—factory-certified engineers perform site acceptance testing (SAT), vacuum validation, and hands-on operator training covering safety protocols, routine calibration, and failure mode diagnostics.
