  • Publication number: 20140102761
    Abstract: A material for providing an electrically conducting contact layer, the material comprising a base material being any one of Ag, Cu, Sn, Ni, a first metal salt of one thereof, or an alloy of one or more thereof. The material further comprises In within a range of 0.01 at. % to 10 at. %, Pd within a range of 0.01 at. % to 10 at. %, and, unless already the base material comprises Sn at a higher amount, Sn within a range of 0.01 at. % to 10 at. %. From such material, a contact layer (6) can be provided that, compared to a coating of only the base material, has improved corrosion resistance and low contact resistance. Also disclosed is: an electrically conducting contact element (2) that comprises a substrate (4) and coated thereon a contact layer (6) comprising the material, a method for providing the contact element (2), and uses of the material as contact layer and target material.

  • Patent number: 7993456
    Abstract: The present invention relates to a device for carrying out a surface treatment of substrates under vacuum, which comprises a housing (1) comprising chambers (2-5) communicate with a vacuum source, at least one of which chambers serves as vacuum lock to the remaining chambers when surface treatment processes are in progress. The housing (1) is divided into an upper and a lower housing half (6, 7) of which at least one has symmetrically distributed recesses (8). Pivotally mounted between the housing halves (6, 7) is a revolver (9), which comprises recesses (10) in which substrate to be treated is placed. The housing halves (6, 7) are designed to be in two positions, in the first of which they are separated from the revolver (9) and in the second of which they are in contact therewith. In the first position the revolver (9) is designed to be turned to predefined rotational positions at which recesses in the housing halves (6, 7) and the revolver (9) coincide in the chambers (2-5).

  • Publication number: 20060073658
    Abstract: In a method for making ferroelectric memory cells in a ferroelectric memory device a first electrode comprising at least one metal layer and optionally at least one metal oxide layer is formed on a silicon substrate which has an optional insulating layer of silicon dioxide. A ferroelectric layer consisting of a thin film of ferroelectric polymer is formed on the top of the first electrode layer and at least a second electrode comprising at least one metal layer and at least one metal oxide layer is formed on the ferroelectric layer. The second electrode is deposited by thermal evaporation of a high-purity evaporation source from an effusion cell onto the ferroelectric layer in a vacuum chamber filled with a gas or a gas mixture.
