Hiden HPR30 Process Gas Analysis Mass Spectrometer

Overview

The Hiden HPR30 Process Gas Analysis Mass Spectrometer is a compact, high-stability quadrupole mass spectrometer engineered for continuous, real-time compositional monitoring of process gases in vacuum and low-pressure industrial environments. Operating on the principle of electron ionization (EI) coupled with mass-selective detection via a radio-frequency (RF) quadrupole mass filter, the HPR30 delivers quantitative and qualitative analysis of gaseous species from residual background gases to reactive process streams. Its design emphasizes robustness under dynamic vacuum conditions—particularly within semiconductor fabrication, thin-film deposition, and plasma processing systems—where rapid response, long-term signal stability, and trace-level sensitivity are critical for process control and fault diagnostics.

Key Features

• Direct re-entrant sampling interface with integrated differential pumping architecture, enabling stable operation across a wide pressure range (1×10⁻⁴ mbar to 1 mbar) without compromising mass resolution or detector lifetime.
• High-sensitivity detection down to 5 parts-per-trillion (ppt) for selected species under optimized conditions; typical quantifiable limit at 5 ppb for common process gases (e.g., H₂, O₂, N₂, Ar, CF₄, SiH₄, NH₃).
• Mass range configurable up to 1000 atomic mass units (amu), supporting analysis of heavy organometallic precursors used in MOCVD and complex fragmentation patterns in plasma chemistry studies.
• Soft ionization mode with adjustable electron energy (1–100 eV), minimizing fragmentation for improved molecular ion identification—essential for distinguishing isobaric compounds and characterizing unstable intermediates.
• Thermally stabilized ion source and detector assembly, delivering < ±0.5% peak height reproducibility over 24-hour continuous operation—meeting GLP-aligned stability requirements for trend-based process validation.
• Integrated pneumatic isolation valve with fail-safe actuation triggered by overpressure (>1.5 mbar), power loss, or user-defined safety thresholds—ensuring system integrity during abnormal process excursions.

Sample Compatibility & Compliance

The HPR30 interfaces directly with vacuum chambers, gas lines, and exhaust manifolds via standardized CF-35 or ISO-KF flanges. It supports reactive, corrosive, and condensable gas streams—including halogenated etchants (Cl₂, BCl₃), silanes (SiH₄, Si₂H₆), ammonia, and metalorganic vapors—when paired with inert sampling capillaries and heated transfer lines (optional). The system complies with CE marking directives (EMC 2014/30/EU, LVD 2014/35/EU) and meets mechanical safety standards per ISO 13857. While not certified for hazardous area installation (ATEX/IECEx), it is routinely deployed in Class 100–1000 cleanrooms and qualifies for inclusion in FDA 21 CFR Part 11-compliant environments when MASsoft audit trails, electronic signatures, and data integrity controls are enabled.

Software & Data Management

MASsoft v6.x provides full instrument control, method development, and real-time spectral interpretation via a Windows-native GUI. Key capabilities include multi-channel time-resolved tracking (up to 100 masses simultaneously), automated peak integration using library-matched retention indices, and configurable alarm logic with email/SNMP notification. All raw spectra, calibration logs, and operator actions are timestamped and stored in encrypted SQLite databases with optional network backup. Audit trail functionality satisfies ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) for regulated QC/QA workflows. Remote monitoring and synchronized multi-system control are supported over standard Ethernet LAN infrastructure.

Applications

• Chemical vapor deposition (CVD), plasma-enhanced CVD (PECVD), and metalorganic CVD (MOCVD) endpoint detection and precursor decomposition monitoring.
• Reactive ion etching (RIE) and deep reactive ion etching (DRIE) plasma composition diagnostics—tracking fluorocarbon radical ratios (CF⁺/CF₂⁺/CF₃⁺) and etch byproduct evolution.
• In-situ contamination analysis during vacuum chamber bake-out, leak testing (He, H₂ tracer), and outgassing profiling of chamber walls and fixtures.
• Process qualification of sputter deposition systems—monitoring target poisoning, argon partial pressure shifts, and oxygen/nitrogen incorporation in oxide/nitride films.
• Real-time reaction kinetics studies in catalytic reactors, fuel cell test benches, and hydrogen purification units operating under sub-atmospheric conditions.

FAQ

What vacuum interface options are available for the HPR30?
Standard configurations include CF-35 conflat flanges with direct re-entrant orifices; custom KF-40, ISO-KF, or DN25 variants are available upon request.
Can the HPR30 operate continuously during chamber venting cycles?
Yes—the differential pumping system and automatic isolation valve allow safe transition between high-vacuum (<10⁻³ mbar) and rough vacuum (up to 1 mbar) without manual intervention or hardware reconfiguration.
Is MASsoft compatible with LabView or Python-based automation frameworks?
Yes—Hiden provides documented TCP/IP and DLL-based APIs for third-party integration, enabling scripted control, data streaming to SCADA systems, and custom dashboard development.
How often does the filament require replacement under typical semiconductor fab usage?
With proper gas handling and routine filament conditioning, average service life exceeds 12 months in controlled CVD/etch environments; MASsoft includes filament usage logging and predictive maintenance alerts.
Does the HPR30 support isotopic ratio measurements for process gas verification?
Yes—mass resolution (M/ΔM > 200 at 10% valley) enables baseline separation of key isotopes (e.g., ²⁸Si/²⁹Si, ¹⁴N/¹⁵N, ³⁵Cl/³⁷Cl), supporting stoichiometric validation of precursor delivery systems.
