In this paper, the prognosis and analysis of the process of the replacement of new lines of innovative products must take into account the capacity of the market, the possible demand for different versions of the product, the presence in the market of competing products – analogs, the...

In this paper, we introduce an approach to optimize manufacturing of an operational amplifier circuit based on field-effect transistors. Main aims of the optimization are (i) decreasing dimensions of elements of the considered operational amplifier and (ii) increasing of performance and...

It has recently been shown that growth of a multilayer structure with one or more delta-layers at high temperature leads to spreading and asymmetrization of the dopant distribution [see, for example, E.F.J. Schubert, Vac. Sci. Technol. A. <Emphasis Type="Bold">8, 2980 (1990), A.M. Nazmul, S. Sugahara, M. Tanaka, J....</emphasis>

We analyze the dopant diffusion in p-n-junction in heterostructure, by solving the diffusion equation with space-varying diffusion coefficient. For a step-wise spatial distribution we find the optimum annealing time to decrease the p-n-junction thickness and to increase the homogeneity of...
