LiNbO3 Substrate for Research & Development

university wafer substrates

Lithium niobate (LiNbO3)

is a useful material for optoelectronics, and many technologies are based on the fact that the material has unique piezoelectrostatic, optical and photoelastic properties, while maintaining mechanical and chemical stability. This makes it attractive for use in integrated optics and as a material of great interest in the field of photonics.

Optical Grade Lithium Niobate

This material was developed as a next generation material by the University of California, San Diego Department of Materials Science and Engineering (DMSE).

The main application is the production of high-performance, cost-effective and high-performance electronic devices. In the case of subgrain and lead-free wafers, damage caused by magnesium doping leads to contamination of the material with lead, lead oxide and lead-containing materials.

Add to this the high cost of lead-free wafers and the lack of a high-quality, cost-effective alternative for the production of electronic devices.

Lithium Niobate Saw Applications

The most commonly used orientation is the YZ (128Adeg) cut, which is best suited for high-end laser cutters such as the MOSFET and XMOS.

Accordingly, the dual-power rotating wafers 171Adeg and 106ADeg have shown increasing interest. The ability to rotate sections at high speed without sound is of growing demand for applications for high-speed sound processing.
