Abstract: 978,849. Semi-conductor devices. CLEVITE CORPORATION. Feb. 14, 1961 [Feb. 15, 1960], No. 5405/61. Heading H1K. In a PN junction device metal precipitates are formed in the space charge region associated with the junction at zero applied bias to modify the field in this region. The most suitable metals for introduction by diffusion are those with high diffusion constants and low but strongly temperature-dependent solubility in the solid semi-conductor. Typical devices are made from a series of 0.04 ohm cm. P-type silicon wafers. Phosphorus pentoxide is deposited on the wafers which are then heated at 1300‹ C. for 15 minutes to form an N-type surface layer. After treatment in hydrofluoric acid for 5 minutes aqueous solutions of ferric nitrate, copper nitrate, manganous nitrate, zinc chloride, and auric chloride respectively are applied to different groups of wafers, and another group is left untreated. After drying, all the wafers are heated at 1000‹ C. for 50 minutes in hydrogen, the heating chamber being purged with nitrogen before and after the treatment in hydrogen. Cooling to room temperature is effected within 6 minutes, wax dots are placed on each wafer and the wafers subdivided by etching between the dots. Apart from those treated with zinc chloride, the treated wafers contained a greater percentage of junctions with soft characteristics than the untreated ones. In an alternative method the metals to be diffused in are applied to the wafers by plating or evaporation. Specification 954,989 is referred to.
