MBE Molecular Beam Epitaxy Equipment
Molecular Beam Epitaxy (MBE) equipment can achieve epitaxial growth processes on certain substrates, enabling molecular self-assembly, superlattices, quantum wells, one-dimensional nanowires, and more. It can be used for process verification and the growth and manufacturing of epitaxial wafers for both second-generation and third-generation semiconductors. The MBE equipment provides an ultra-high vacuum environment during thin film epitaxial growth, creating an ideal setting for this process. It effectively eliminates various interference factors during film growth, resulting in high-precision thin films.

Molecular Beam Epitaxy (MBE) EquipmentThis equipment can achieve epitaxial growth processes on certain substrates, enabling molecular self-assembly, superlattices, quantum wells, one-dimensional nanowires, etc. It can be used for process verification and epitaxial wafer growth and manufacturing of second-generation and third-generation semiconductors.
The molecular beam epitaxy equipment has an ultra-high vacuum environment during thin film epitaxial growth, providing an ideal environment for thin film growth. It can eliminate various interference factors during film growth, resulting in ideal high-precision films.
The molecular beam epitaxy experimental equipment designed and manufactured by our company comes in experimental and production types, with reasonable configuration, simple structure, easy operation, advanced technology, reliable performance, versatile applications, strong practicality, and relatively low prices, suitable for laboratories and research institutions in universities for teaching experiments, scientific research, and process experiments in molecular beam epitaxy.Production-type MBE can be used for the preparation of small batches of epitaxial wafers.
Functional Features
This project completed the full domestic research and development design and manufacturing of a complete set of MBE in 2005, achieving independent control. It independently designed core components such as the ultra-high vacuum epitaxial growth chamber, process control system and software, RHEED in-situ real-time monitoring instrument, linear electron gun, high-temperature source furnace, source furnace power supply, high-temperature sample stage, and film thickness gauge (which can measure the number of molecular layers grown epitaxially).
It can achieve epitaxial growth of second-generation semiconductors (such as gallium arsenide) and third-generation semiconductors (such as silicon carbide and gallium nitride). After more than a decade of process exploration, the equipment design has been continuously upgraded, and it now has the capability to design and manufacture production-type MBE equipment. The equipment has reasonable configuration, simple structure, advanced technology, reliable performance, versatile applications, strong practicality, and high performance-to-price ratio.Equipment Composition and Main Technical Indicators
