LiTaO3 (Lithium Tantalate) on Si (Silicon) Bonded Wafers are engineered substrates that are created by bonding a thin layer of LiTaO3 crystal onto a silicon wafer. LiTaO3 is a piezoelectric crystal, which means it generates an electrical charge in response to mechanical stress. This makes it useful in applications such as sensors and actuators, as well as in high-frequency electronics, such as oscillators and filters.
The bond between the LiTaO3 and silicon is created using a process known as wafer bonding, which involves the application of high pressure and temperature to bring the two materials into intimate contact. The resulting bonded wafer has a very high level of mechanical and electrical stability, which makes it ideal for use in many high-performance electronic applications.
