    Abstract: A semiconductor device has an integrated passive device (IPD) formed over a substrate. The IPD can be a metal-insulator-metal capacitor or an inductor formed as a coiled conductive layer. A signal interconnect structure is formed over the first side or backside of the substrate. The signal interconnect structure is electrically connected to the IPD. A thin film ZnO layer is formed over the substrate as a part of an electrostatic discharge (ESD) protection structure. The thin film ZnO layer has a non-linear resistance as a function of a voltage applied to the layer. A conductive layer is formed over the substrate. The thin film ZnO layer is electrically connected between the signal interconnect structure and conductive layer to provide an ESD path to protect the IPD from an ESD transient.

  • Patent number: 8218803
    Abstract: In the case of a receiver facility to be fixed in the auditory canal, particularly for hearing devices with an external receiver, the receiver is to be mounted in the earmold in an acoustically advantageous fashion which guards against contaminations and is also easily exchangeable. Provision is thus made for a receiver facility with a longish receiver and a earmold, which has a borehole, into which the receiver is inserted. A tubular connector, which is more elastic than the receiver and the earmold, is used to accommodate for the most part the longitudinal extension of the receiver in a friction-locking fashion. The connector is for its part force-fitted into a borehole of the earmold in a friction-locking fashion. The receiver is thus elastically mounted and can be easily removed from the earmold together with the connector with the aid of a pin-like tool for replacement purposes.
