Improved biasthermal-stress method for the insulator charge measurement of BN/InP MIS structures
A modified biasthermal-stress method for insulator charge characterisation is described. The procedure is applied to optimise the deposition parameters of a boron-nitride (BN) insulator on an indium phosphide (InP) semiconductor. The deposition of the BN films is performed at low temperatures using a microwave plasma enhanced CVD system. A complete characterisation of both mobile and fixed charges in the BN films is performed and the methodology to verify the results is illustrated.
