Abstract

1377699 Semi-conductor devices SUWA SEIKOSHA KK 31 Oct 1972 [10 Nov 1971] 50135/72 Heading H1K In making a semi-conductor device a layer of polycrystalline silicon containing at least two types of impurity is formed on a silicon substrate and the impurities diffused from the layer into the substrate. As described the layer is deposited to a thickness of several hundred Š to several Á by feeding a mixture of silane, phosphine and boron hydride into a reaction chamber containing the substrate which is held at 500 to 700‹ C. The layer may be deposited over the entire substrate and reduced by photoetching to areas where diffusion is required. Oxide is deposited over the layer prior to diffusion, which may be effected in oxygen. After diffusion the polycrystalline silicon may be oxidized throughout its thickness. Surface concentrations from 10<SP>14</SP> to 10<SP>20</SP> atoms/cc. are obtainable by the method.
