Experimental and modelled configuration of double-barrier HBV based on Al0.7Ga0.3As/GaAs

Results are presented on device models for an optimisation of processes. In particular the double-barrier Al0.7Ga0.3As/GaAs Heterostructure Barrier Varactor (HBV) designed using the commercial software Synopsys ISETCAD c, with accuracy higher than generally published. The design takes into account all the technological steps that are involved during the development of the HBV. The comparison with the measurements shows that the accuracy is higher than standard available models.
