Method for manufacturing a thin-layer component, in particular a thin-layer, high-pressure sensor, and thin-layer component
First Claim
1. A method for manufacturing a thin-layer component, comprising:
- depositing a resistive layer for forming a measuring element on an electrically non-conductive surface of a diaphragm layer; and
depositing a contact-layer system for electrically contacting the measuring element on the measuring element in such manner that one of no steps and steps that are small in comparison with a thickness of the contact-layer system are covered.

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.
