Threshold Voltage Improvement Scheme for High-voltage IGBT

The threshold voltage, commonly abbreviated as Vth or VGS(th), of a field-effect transistor (FET) is the minimum gate-to-source voltage (VGS) that is needed to create a conducting path between the source and drain terminals. It is an important scaling factor to maintain power efficiency. When referring to a junction field-effect transistor (JFET), the threshold voltage is often called pinch-off voltage instead. This is somewhat confusing since pinch off applied to insulated-gate fi… Web25 nov. 2024 · IGBT stands for Insulated-gate-Bipolar-Transistor, a power semiconductor which includes the features of a MOSFET's high speed, voltage dependent gate … Web20 okt. 2024 · Threshold Voltage Improvement Scheme for High-voltage IGBT Abstract: In this paper, the impact of silicon nitride process on threshold voltage (V th ) in an IGBT … pogoh pittsburgh
