Abstract :
The hot carrier stress induced device degradation of a p-type LDMOS high voltage transistor is investigated at different stress conditions. The influence of shallow trench corner rounding and carbon ion implantation into the shallow trench region is discussed. Numerical device simulations, charge pumping measurements and electrical characterisations are used for these investigations.
