10 dark violet to red-violet 0. A slight redistribution of the implanted atoms before annealing and their substantial migration towards the surface during annealing depending on the sequence of implantations are observed. In carrying out the process of the invention, for example, in one of its embodiments, an oxide layer is first deposited on a surface of a semiconductor wafer.


While these Gallium diffusion in silicon dioxide may be active with respect to surface oxidation, it is more likely that an electron transfer occurs from the semiconductor surface yields activated oxygen species, which are the actual reactants in the oxidation of the silicon. 239000011965 hydrofluoric acid Substances 0. This opening can be formed by any usual photo-lithographic process, for example, a photo-resist, namely, a light sensitive masking material, is initially applied over the layer 16.

5 eV, approximately equal to the average of the activation energies listed in table II. Incorporation of oxygen at the outer surface into the silicon oxide film. doping materials, electrode materials, into or out of a semiconductor body, or between semiconductor regions; Interactions between two or more impurities; Redistribution of impurities using diffusion into or out of a solid from or into a solid phase, e.

H impurities in the deposited films, vs. Other vapor plated glass materials, as for example aluminum borosilicate or aluminum silicate may be used in place of silicon dioxide. 72 blue-green to gree 0. 229910010271 silicon carbide Inorganic materials 0. Almost a complete annealing of displacement damage is possible for shallow implants provided loop-coalescence does not lead to the formation of cross-grid of dislocations. The vapor plated glass materials are not resistant to the diffusion of certain dopant materials and thus diffusion of these particular materials will take place through the mask.

P2O5, PSG, H3BO3, doped oxides• For both boron and phosphorus, high concentrations and high temperatures lead to the formation of a liquid or quasi-liquid Gallium diffusion in silicon dioxide phase in which transport is rapid.

They are used to generate positively p-type or negatively n-type doped regions in the semiconductor. Fair [14] proposes that diffusion of boron and phosphorus in silicon dioxide proceeds via peroxide defects, that is: Fig.
