SUMMARY
The oxide layer in MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistors) serves as a critical insulator that separates the gate from the channel, enabling voltage control over the channel conductivity. This layer, typically silicon dioxide (SiO2), is essential for the device's operation, affecting parameters such as threshold voltage and leakage current. The discussion emphasizes the importance of oxide thickness and quality in enhancing MOSFET performance, particularly in modern applications where miniaturization is key.
