A vector majorization method for solving a nonlinear programming problem
AbstractIn the rounding error analysis of a so-called hyperbolic rotation algorithm applied to downdating the Cholesky factor, a sharp upper bound is needed for a product where a = (a1,…,anT ϵ Rn, ∥a∥ ⩽ θ < 1, and θ is fixed. It is shown that In the original proof by Pan and Sigmon, the principle of Lagrange multipliers was used. A second proof by using vector majorization is presented here, which provides insights into this rather strange-looking bound. Moreover, the new proof can be readily generalized to solve a large class of nonlinear programming problems

Reactively sputtered RuO2 diffusion barriers
The thermal stability of reactively sputtered RuO2 films is investigated from the point of view of their application as diffusion barriers in silicon contact metallizations with an Al overlayer. Backscattering spectra of Si/RuO2/Al samples and electrical measurements on shallow junction diodes with Si/TiSi2.3/RuO2/Al contacts both show that RuO2 films are effective diffusion barriers between Al and Si for 30-min annealing at temperatures as high as 600°C
