RIBER MBE Epitaxy System

Core FunctionUltra-high vacuum epitaxial growth system used for precise deposition of crystalline thin films,primarily for compound semiconductors (III-V materials such as GaAs, InP, etc.).

Vacuum & Chamber Architecture- UHV growth chamber with multi-port geometry – Cryogenic and turbomolecular pumping – Loadlock / transfer capability (typical for Riber systems) – Base pressure in 10■¹■Torr range

Key Subsystems Identified- Effusion cell power supplies (multi-channel rack) – RF plasma source (Advanced Energy Cesar RFgenerator) – Hiden Analytical system (likely RGA or mass spec) – SPECS control electronics -Cryogenic temperature controller – Beam equivalent pressure (BEP) monitoring controls

Deposition Capabilities- Molecular Beam Epitaxy (MBE) – Elemental and compound semiconductor growth – Ultra-precisethickness and composition control – Layer-by-layer epitaxial deposition

Process Control- Independent source temperature control (effusion cells) – RF plasma for reactive species (e.g.,nitrogen, oxygen) – In-situ monitoring via RGA / diagnostics – Automated recipe control viaintegrated electronics racks

Typical Applications- Semiconductor device R&D; (GaAs, InGaAs, AlGaAs, etc.) – Quantum structures (quantum wells,dots) – Optoelectronics (lasers, LEDs, detectors) – Advanced materials research

High-complexity, high-value research system. Requires specialized operators and cleanroom integration. Designed for precision rather than throughput.
