What is The Role of Gate Oxide in MOS Devices?3 answersThe gate oxide in MOS devices plays a crucial role in their performance and reliability. It determines the current flow through the channel regions and controls the device's behavior. Different methods have been proposed to determine the effective gate oxide film thickness, such as using first principle calculations and comparing the atomic structure of the device. The thickness of the gate oxide layer can vary across different regions of the device, with the edge of the gate and the source/emitter regions having different thicknesses compared to the channel regions. Various materials, such as Al(ON), AlN, and Al2O3, have been studied for gate dielectrics to improve interface state density, dielectric strength, and reliability. Gate oxide reliability is an important aspect to consider, as stress conditions and long-term AC gate bias can affect the device's behavior and parametric shifts in threshold voltage and on-resistance. By optimizing the gate oxide structure, the current driving capability of the MOS device can be maintained while improving the withstand voltage between the source and the drain.
