A method reducing microbial growth uses an inorganic substance consisting of MoOand/or MoOwhich causes the formation of hydrogen cations when in contact with an aqueous medium to achieve an antimicrobial effect. The substance is present as a layer or a component of a layer, and is present in combination with one or more materials as a composite material. The composite material has a polymer matrix, and the substance is incorporated at 3 to 50% by weight into the composite material.

Substance with an antimicrobial effect

A package is configured as a composite component with a substrate, at least one semiconductor component, and an enclosure, which are joined to one another. The heat-dissipating substrate is a single-layer or multilayer substrate with a thermal conductivity, transversely with respect to a joining surface to which the semiconductor component is joined, of greater than 170 W/m. The substrate may be a layered structure and/or a structure of graduated material composition, and it has an asymmetrical thermal expansion characteristic. By suitable selection the layers or the material graduation, it is possible to reduce and limit the shear distortion of the composite component formed of the substrate, the semiconductor component, and the enclosure.
