Wide bandgap device TCAD simulation
TCAD simulation provides many benefits such as reducing the time and manufacturing cycles spent to develop semiconductor technologies or increasing the understanding of mechanisms involved in innovative devices using emerging materials and heterostructures by visualizing internal physical processes.
We developed a methodology to simulate complex devices based on TCAD SILVACO simulation and modelling coupled with ADS software in order to reproduce and predict device behavior both in small and large signal regimes.
