20170092640 · 2017-03-30 ·

Semiconductor devices and methods are described wherein temperature dependence of leakage current in at least one pathway of a device is compensated by a resistor in the device. Control of temperature dependent leakage current is particularly useful for silicon nitride devices and for circuits such as cascode circuits. A semiconductor leakage current that increases with temperature may be compensated by a fabricated resistor such as a boron doped polysilicon resistor that is electrically connected to compensate the leakage current in the pathway.
