Overview
The ADVANCE RIKO MILA-5000 Series Desktop Rapid Thermal Annealing (RTA) System is a compact, high-performance thermal processing instrument engineered for semiconductor process development, thin-film optimization, and materials science research. Based on infrared (IR) radiant heating using gold-coated reflectors and halogen lamp arrays, the system delivers precise, localized, and contamination-free thermal energy to substrates—enabling rapid, repeatable, and highly controllable annealing cycles without bulk furnace lag. Unlike conventional tube or box furnaces, the MILA-5000 employs a transient thermal profile architecture: heat is delivered directly to the sample surface via broadband IR radiation, while integrated water-cooled chamber walls and active gas flow management ensure sub-second thermal quenching. This design conforms to fundamental RTA principles defined in SEMI F26 and ASTM F1942 standards for rapid thermal processing characterization.
Key Features
- Infrared gold-mirror heating configuration for high emissivity, low thermal inertia, and minimal cross-contamination
- Integrated quartz reaction chamber with O-ring sealed flange assembly—compatible with vacuum (down to 10−5 Pa in MILA-5000UHV variant), inert gas (N2, Ar), forming gas (N2/H2), and ambient air environments
- Real-time optical access via top-mounted fused silica viewport (UV-grade, 300–2500 nm transmission), enabling in situ visual monitoring and synchronized high-speed imaging (up to 1000 fps with optional camera integration)
- Dual-mode temperature control: front-panel programmable PID controller with real-time overlay of setpoint vs. measured thermocouple (Type K) or pyrometer (optional 2-wavelength) feedback
- USB 2.0 interface supporting PC-based operation via ADVANCE RIKO’s proprietary RTA Control Suite v4.x—compliant with Windows 10/11 and compatible with LabVIEW™ drivers for custom automation
- Modular cooling architecture: closed-loop deionized water circuit with flow rate monitoring (≥4 L/min) and thermal cutoff safeguards ensures reproducible 200 K/s quench rates
Sample Compatibility & Compliance
The MILA-5000 accommodates standard 2-inch (50.8 mm) wafers, diced die, TEM grids, and planar thin-film coupons on quartz, silicon, sapphire, or SiC carriers. Its low-particulate quartz chamber and metal-sealed UHV option (MILA-5000UHV) meet Class 100 cleanroom handling requirements per ISO 14644-1. The system supports process validation under GMP-aligned workflows: temperature profiles are logged with timestamped, audit-trail-enabled data files compliant with FDA 21 CFR Part 11 when used with validated software configurations. All thermal cycles adhere to ASTM F1942-22 (“Standard Practice for Characterizing Rapid Thermal Processing Equipment”) and are traceable to JIS Z 8703 reference temperature standards.
Software & Data Management
The RTA Control Suite provides full-cycle programmability—including ramp-hold-cool sequences, multi-step isotherms, and conditional branching based on real-time temperature deviation thresholds. Each run generates a binary .rta file containing time-stamped thermocouple/pyrometer readings, lamp power output (%), gas flow rates (if equipped with MFC), and chamber pressure (for UHV models). Export formats include CSV, MATLAB .mat, and XML for integration into MES platforms. Data integrity is enforced via SHA-256 checksums, user-level access controls (admin/operator/guest), and automatic backup to network drives or NAS endpoints.
Applications
- Activation annealing of ion-implanted dopants (e.g., B, P, As in Si, SiGe, GaN)
- Crystallization of amorphous silicon, IGZO, and metal oxide semiconductors
- Thermal budget optimization for CMOS gate stack formation and silicide phase transformation
- Post-deposition annealing of ALD/CVD dielectrics (HfO2, Al2O3) to reduce fixed charge and interface trap density
- Process window mapping for RTP-compatible MEMS release and packaging steps
- Accelerated aging studies of photovoltaic absorber layers (CIGS, perovskites) under controlled atmospheres
FAQ
What vacuum level does the MILA-5000UHV achieve, and how is it maintained?
The MILA-5000UHV model reaches base pressures of ≤1×10−5 Pa using a turbomolecular pump backed by a dry scroll pump; vacuum integrity is verified via residual gas analysis (RGA) and leak-checked per ISO 20484.
Can the system perform temperature calibration traceable to NIST standards?
Yes—optional blackbody cavity calibration kits (traceable to NMI-Japan) and dual-wavelength pyrometers enable emissivity-compensated measurements with ±0.5% uncertainty at 1000 °C.
Is the quartz chamber replaceable, and what is its typical service life under routine use?
Quartz tubes are field-replaceable consumables; average lifespan exceeds 500 cycles at 1100 °C in inert atmosphere, subject to proper cooldown sequencing and particulate filtration.
Does the system support integration with in-line metrology tools such as ellipsometers or four-point probes?
Yes—standard RS-232 and TTL trigger I/O ports enable hardware synchronization with external measurement systems; timing jitter is <10 µs for coordinated anneal–measure sequences.
