A new two-dimensional process modeling program written in Fortran is described. For the first time, this program allows the simulation of all important processing steps occurring in typical sequences involved in the fabrication of integrated circuits such as doping, oxidation, lithography, etching, and layer deposition. The program possesses a modular(More)
Three-dimensional (3D) simulations of conventional and collimated sputter deposition of titanium into contact holes with high aspect ratios have been carried out using a 3D topography simulator. In this simulation program the device surface is discretized by a set of triangles. The layer growth rate for each triangle is determined by calculating the flux of(More)
Piezoelectric transformers (PTs) reveal a promising potential to replace conventional transformers in driving circuits for switching power applications, e.g. high-side driver for IGBT or MOSFET switches. With the realized driver design it is possible to transfer - galvanically insulated - both energy and information with one single PT. Above all, adapted(More)
