Due to the optimization, one can also obtain increasing of homogeneity of dopant in doped area. In this paper, we consider manufacturing of a field-effect heterotransistor without p-njunction. Framework the approach of manufacturing, we consider a heterostructure with specific configuration, doping required parts of the heterostructure by dopant diffusion or by ion implantation and optimization of annealing of dopant and/or radiation defects. The optimization gives us possibility to decrease dimensions of field-effect transistors. We introduce an analytical approach to model technological processes without crosslinking concentrations of dopant and radiation defects on interfaces between layers of heterostructure.
