Drain-induced barrier lowering (DIBL) is a short-channel effect in MOSFETs referring originally to a reduction of threshold voltage of the transistor at higher drain voltages. In a classic planar field-effect transistor with a long channel, the bottleneck in channel formation occurs far enough from the drain contact that it is electrostatically shielded from the drain by the combination of the substrate … WebApr 6, 2024 · The on/off current ratio was only 200 due to gate leakage through the dielectric. The poor oxide quality also impacted gate control and drain-induced barrier lowering (DIBL). Destructive breakdown occurred around 20V. The p-FETs were affected by the gate recess depth, where a second threshold was seen with deep recessing. …
