  • Publication number: 20050275502
    Abstract: Proposed is a method for manufacturing a thin-layer component, in particular a thin-layer, high-pressure sensor, as well as a thin-layer component, where a resistive layer for forming measuring elements, in particular strain gauges, is deposited on an electrically non-conductive surface of a diaphragm layer, a contact-layer system for electrically contacting the measuring elements being deposited on the measuring elements in such a manner, that regions of the measuring elements are situated between each region of the contact-layer system and the diaphragm layer. This is used to provide, in particular, a high-pressure sensor, in which the capacitances of the contacts of the contact-layer system are designed to be symmetric.
    Type: Application

  • Publication number: 20040026367
    Abstract: Proposed is a method for manufacturing a thin-layer component, in particular a thin-layer, high-pressure sensor, as well as a thin-layer component, where a resistive layer for forming measuring elements, in particular strain gauges (30), is deposited on an electrically non-conductive surface of a diaphragm layer (10, 20), a contact-layer system (41) for electrically contacting the measuring elements being deposited on the measuring elements in such a manner, that regions of the measuring elements (30) are situated between each region of the contact-layer system and the diaphragm layer (10, 20). This is used to provide, in particular, a high-pressure sensor, in which the capacitances of the contacts of the contact-layer system are designed to be symmetric.

  • Patent number: 6620644
    Abstract: A manufacturing method for a thin-layer component, in particular a thin-layer high-pressure sensor, having a substrate on which the at least one functional layer to be patterned is to be deposited in the steps, preparing the substrate; depositing the functional layer on the substrate; and patterning the functional layer via a laser processing step, the laser processing step being selective with respect to the substrate.
