Annealsys AS-ONE 100 High-Vacuum Rapid Thermal Annealing Furnace

Overview

The Annealsys AS-ONE 100 is a high-precision, vertically oriented rapid thermal processing (RTP) furnace engineered for semiconductor research, process development, and advanced materials fabrication. Designed and manufactured in France, it employs high-intensity infrared (IR) lamp arrays—12 lamps delivering up to 30 kW—to achieve ultra-fast, controllable thermal transients under high-vacuum or precisely regulated gas atmospheres. Its core operational principle relies on radiative heating of wafers via broadband IR radiation, enabling non-contact, spatially uniform thermal profiles with minimal thermal mass interference. This architecture supports true rapid thermal annealing (RTA), rapid thermal oxidation (RTO), silicidation, nitridation, and crystallization processes where millisecond-scale thermal budgets and sub-second ramp rates are critical to preserving dopant profiles, minimizing interdiffusion, and controlling interface chemistry.

Key Features

• High-vacuum capability down to 10⁻⁶ Torr using integrated turbomolecular pumping system, ensuring ultra-clean processing environments essential for compound semiconductor and 2D material synthesis.
• Real-time dual-sensor temperature monitoring: combined K-type thermocouple (for low-to-mid range stability) and dual-range optical pyrometer (150–1100 °C and 400–1500 °C) for accurate, non-contact surface temperature measurement across the full operational range.
• Digital PID control architecture with adaptive tuning algorithms ensures stable setpoint tracking, repeatability better than ±1% in both accuracy and radial uniformity over 150 mm (6-inch) substrates.
• Modular gas delivery system featuring five independent mass flow controllers (MFCs), supporting sequential or simultaneous introduction of inert (N₂, Ar), reactive (O₂, NH₃, H₂, forming gas), or precursor gases through quartz-lined inlet lines.
• Optimized chamber geometry with 200 mm diameter × 25 mm depth cavity and fused silica viewport enables in situ optical monitoring (e.g., reflectance, ellipsometry) and facilitates integration with external metrology tools.
• Rugged mechanical design with water-cooled lamp housing and forced-air lamp cooling ensures long-term operational stability and lamp lifetime consistency across thousands of thermal cycles.

Sample Compatibility & Compliance

The AS-ONE 100 accommodates standard semiconductor wafers up to 150 mm (6-inch) in diameter—including Si, SiC, GaAs, InP, sapphire, quartz, and flexible metal foils—with optional custom substrate holders for non-planar or patterned samples. All wetted surfaces are constructed from ultra-high-purity quartz and stainless steel (316L), compliant with SEMI F57 standards for particle generation control. The system meets ISO 9001 manufacturing traceability requirements and supports GLP/GMP-aligned operation through configurable audit trails, user access levels, and electronic signature-ready logging (compatible with FDA 21 CFR Part 11 when deployed with validated software extensions). Vacuum and gas safety interlocks conform to EN 61508 SIL2 functional safety requirements.

Software & Data Management

Control and data acquisition are managed via Annealsys’ proprietary RTA-Studio software running on an embedded industrial PC. The interface provides full recipe-based automation—including multi-zone ramp/soak/cool sequences, gas switching logic, vacuum sequencing, and real-time temperature profiling. All process parameters, sensor readings, and alarm events are timestamped and stored in ASCII- and HDF5-compatible formats for seamless export into MATLAB, Python, or statistical process control (SPC) platforms. Optional OPC UA server module enables integration into factory-wide MES/SCADA systems. Data integrity safeguards include cyclic redundancy checks (CRC), write-once archival mode, and encrypted local backups.

Applications

• Rapid thermal annealing (RTA) of ion-implanted silicon wafers to activate dopants while suppressing transient enhanced diffusion (TED).
• Rapid thermal oxidation (RTO) for ultrathin gate oxide growth (< 2 nm) with precise stoichiometric control.
• Formation of low-resistance silicide contacts (NiSi, CoSi₂, TiSi₂) on advanced CMOS nodes.
• Nitridation of SiO₂/SiON interfaces for high-k dielectric stacks.
• Selenization and sulfurization of CIGS and CZTS absorber layers in thin-film photovoltaics.
• Graphene chemical vapor deposition (CVD) and controlled carbon nanotube (CNT) growth on catalytic substrates.
• Crystallization of amorphous silicon, IGZO, and phase-change materials (e.g., Ge₂Sb₂Te₅) for memory and display applications.
• Densification of sol-gel derived dielectrics and ferroelectric thin films without cracking or delamination.

FAQ

What vacuum level does the AS-ONE 100 achieve, and is a high-vacuum option standard?
Standard configuration includes a turbomolecular pump achieving ≤10⁻⁶ Torr base pressure; no upgrade is required for high-vacuum operation.

Can the system be qualified for use in a Class 100 cleanroom environment?
Yes—the AS-ONE 100 is designed with sealed electronics, low-outgassing materials, and vibration-damped mounting to meet ISO Class 5 (Class 100) cleanroom compatibility requirements.

Is remote monitoring and control supported over Ethernet or industrial protocols?
Yes—RTA-Studio supports TCP/IP-based remote desktop access, and optional OPC UA or Modbus TCP gateways enable integration with central facility monitoring systems.

What calibration documentation is provided upon installation?
A full NIST-traceable temperature calibration report (pyrometer and thermocouple), vacuum gauge certification, and MFC flow verification data are included with each shipment.

Are spare lamps and quartz components available as consumables?
Yes—Annealsys maintains global inventory of IR lamps, quartz viewports, sample boats, and gasket kits with documented shelf-life and lot-specific QC certificates.
