Customized Silicon-on-Insulator (SOI) Wafer (4"-8")

To better serve you, we would like to discuss your specific requirement, Please Contact Us for a quote.

Silicon-on-Insulator (SOI) wafer is a structure including the device layer (top), buried oxide layer (middle), and handle wafer (bottom). This technology allows for the continuous miniaturization of microelectronic devices. It has several advantages over a traditional silicon wafer, like low leakage currents and low parasitic capacitance. It is used in various applications, including MEMS, sensors, telecommunications, and power devices. For example, the researchers at Toyota Central R&D Labs proposed simple T-shaped support as a solution to the tilt deformation caused by the residual stress. This solution could potentially allow for the development of high-precision sensors and actuators.
