A semiconductor component has a semiconductor body with at least on pn-junction therein, extending to the surface of the semiconductor body, and has a passivation layer composed of boron-doped, amorphous, hydrogenous carbon (A-C:H) which covers at least the portion of the pn-junction extending to the surface, the boron content of the passivation layer being between 0.1 per mil and 4% by weight. The passivation layer is manufactured on the semiconductor body by deposition from a high-frequency, low-pressure plasma which is generated in a mixture of gaseous, organic compounds containing carbon and hydrogen and gaseous, organic boron compounds.

A lyophobic layer is produced on surfaces of a jet-orifice carrier of a recording device functioning with fluid droplets by generating a uniform and pore-free layer on surfaces of the carrier with the application of high frequency/low pressure glow discharge using a gaseous organic compound, such as octofluorocyclobutane.

Method for producing a lyophobic layer

The invention relates to an electrocatalyst capable of being used, in particular, in anodes of fuel cells with acid electrolyte, and to a process for the manufacture of this electrocatalyst. The electrocatalyst contains at least one ternary metal compound which is composed of one metal of the iron group of the periodic table of elements, i.e. iron, cobalt or nickel, and two different elements of the phosphorus, arsenic, antimony, bismuth, sulfur, selenium and tellurium group, and has semiconducting characteristics. Examples of such ternary metal compounds serving as electrocatalysts are FePS, CoPS and CoAsS. The new electrocatalysts show a high catalytic effect and are insensitive to catalyst poisons.
