Abstract: A simultaneous double diffusion method wherein a coating containing a silicon oxide and the oxides of a plurality of conductivity-determining impurities having different diffusivity rates is formed on the surface of a semiconductor substrate using a temperature at which substantially no diffusion of the impurities into the substrate will take place. Then, the substrate is heated to simultaneously diffuse the impurities into the substrate to form a plurality of abutting regions in the substrate separated by junctions. The sequence of regions in distance, with respect to the substrate surface, is controlled by the diffusivity rates of the selected conductivity-determining impurities. The coating may be a single layer or a plurality of layers, at least two of which contain different conductivitydetermining impurities.

Abstract: A homogeneous diffusion source and method of producing wherein a semiconductor dopant material and a finely divided semiconductor material are introduced into a capsule in spaced relation, the capsule evacuated, and the capsule introduced into a multiplezone furnace. The temperature of the semiconductor material and the dopant material are maintained until equilibrium is substantially achieved.
