Abstract: ABSTRACT           A composition for producing adherent deposits of palladium from cya-nide-free bath uses small amounts of cobalt or nickel or the combination there-of as the brightener. The bath employs as an electrolyte alkali metal and ammoni-um sulfates, sulfamates, phosphates, nitrates, nitrites and mixtures thereof. Preferably, the brightener concentration is 0.004-0.02 gram mole per liter nickel or 0.002-0.04 gram mole per liter cobalt, or the combination thereof. Cetyltrimethylammonium bromide is an optional component for the bath which is maintained at a pH of 7.5-11.0 and at a temperature of 28°-80° Centigrade. For barrel plating, the current density is 0.05-0.5 amperes per square decimeterand for rack plating the current density is 0.2-2.0 amperes per square decimeter.

Abstract: A SCHOTTKY BARRIER SEMICONDUCTOR DEVICE AND                  METHOD OF MAKING SAME                       ABSTRACT             A first layer of semiconductor device is of doped amorphous silicon prepared by a glow discharge in a mixture of silane and a doping gas.  The first layer is on a substrate having good electrical properties.  On the first layer and spaced from the substrate is a second layer of amorphous silicon prepared by a glow discharge in silane.  On the second layer opposite the first layer is a metallic film forming a surface barrier junction there-between, i.e. a Schottky barrier.  The first layer is doped so as to make an ohmic contact with the substrate.           Preferably the doping concentration of the first layer is graded so the dopant concentration is maximum at the interface of the first layer and the substrate.  In a second embodiment of the Schottky barrier semiconductor device an intermediate layer is between and contiguous to both the first layer and the substrate.  The intermediate layer facilitates in making ohmic contact between the amorphous silicon and the substrate.  Annealing and heat treating steps are performed in the fabrication of the Schottky barrier device to increase device efficiency.
