The high contact resistance which is caused by high concentration or supersaturation of metal oxides including tin oxides about contact surfaces, is avoided by having solute metals sublimated, reduced or extracted about the contact surface before the internal oxidation thereof. Sublimation and other treatments may be made after having the materials subjected to internal oxidation.

Abstract: A method for forming a shallow and highly concentrated arsenic doped surface layer in a silicon bulk region includes the steps of forming an arsenic doped polysilicon layer in contact with a preselected area of a bulk region surface in which the surface layer is to be formed and completely oxidizing the polysilicon layer at a rate exceeding the rate at which arsenic diffuses in the bulk region. Since arsenic has a relatively high silicon/silicon dioxide segregation coefficient and the oxidation rate exceeds the arsenic diffusion rate, arsenic accumulates at the silicon dioxide/silicon interface during oxidation, and nearly all of the arsenic in the region of the polysilicon layer above the preselected area is driven into the bulk region surface by the oxidation to form an impurity layer having a very high surface concentration of arsenic.
