What is SOI Wafer ?
A SOI (Silicon-On-Insulator) wafer is a type of semiconductor wafer used in the manufacturing of integrated circuits (ICs). It is characterized by a layered structure consisting of a thin layer of silicon (the active layer) on top of an insulating layer, which is usually made of silicon dioxide (SiO2). The insulating layer, also known as the buried oxide (BOX), separates the active layer from the underlying silicon substrate. The purpose of using an SOI wafer is to improve the performance and power efficiency of ICs. The insulating layer reduces parasitic capacitance and leakage currents, thereby enhancing the speed and reducing the power consumption of the devices fabricated on the wafer. Additionally, the SOI structure helps to minimize the interference between neighboring transistors, leading to better isolation and reduced crosstalk.

Product Application
The purpose of using an SOI wafer is to improve the performance and power efficiency of ICs. The insulating layer reduces parasitic capacitance and leakage currents, thereby enhancing the speed and reducing the power consumption of the devices fabricated on the wafer. Additionally, the SOI structure helps to minimize the interference between neighboring transistors, leading to better isolation and reduced crosstalk. SOI technology offers several advantages over traditional bulk silicon wafers. It enables the fabrication of high-performance devices, such as microprocessors, memory chips, and RF (radio frequency) circuits. SOI wafers are particularly advantageous for applications that require low power consumption, high-speed operation, and excellent isolation between components.
