Ultra-thin single crystal diamond membrane

The technology

The scalable method produces high-quality ultra-thin single crystal diamond membranes. They are suitable for a wide range of applications in optics, sensing, quantum computing and filtration. They are also suitable for use as high-strength, ultra-thin vacuum windows.

Market need

Industrially scalable fabrication methods are needed to exploit the superior chemical, physical and structural properties of single crystal diamond for use in integrated photonics.

Technology status

The method produces thin (<300 nm) large-area, single crystal diamond membranes at up to half the cost of current techniques. The membranes and their method of fabrication are the subject of a patent application. Further research and development is underway to explore new applications of the technology.
