DA Scientific Equipment Ltd. has over 10 years experience in developing highly specialized process equipment for semiconductor crystal growth. These platforms are often one of kind for the production of new novel materials by traditional or new growth method. We have produced Czochralski, Bridgman and Vertical Gradient Freeze (VGF) systems. We also have experience in producing a wide range of solution growth equipment including Travelling Heater Method (THM) systems and Liquid Phase Epitaxy (LPE) systems. Our systems are developed to meet the specific needs of the project, from fully flexible for process development to streamlined for production. In addition to growth systems, we also have extensive experience in developing associated infrastructure for cutting, polishing, sealing, etc.
Some examples of recent projects:
- Czochralski Crystal Grower for Melt Replenishment Development. 4" to 8" hot zone for SiGe growth development.
- Liquid Phase Diffusion Growth Platform for SiGe. Reasearch platform for study of growth technique under a number of combined stimuli including static magnetic field, rotating magnetic field, ampoule translation, ampoule rotation and electric field.
- Solidification Research Furnace with in situ observation of interface position. This platform integrated a infrared sensor for interface tracking with a vacuum furnace, rotating magnetic field and static magnetic field for research into metal casting.
- Bridgman Crystal Growth Platform for II-IV material production. Flexible platform for Bridgman type growth development.
- Vertical Gradient Freeze Growth Platform for process development. Fully integrated system for development of gradient freeze growth process.
Our expertise in crystal growth equipment translates very well to process equipment across the spectrum of applications. We welcome the opportunity to discuss your application and the solution we can provide.
