    摘要: A piezoelectric relay requiring less piezoelectric material than conventional piezoelectric relays is disclosed. The relay differs from conventional relays in that the contacts are touching with essentially no force applied between the contacts when no power is applied to the relay.

    摘要: An area saving dielectrically isolated semiconductor structure is disclosed which allows for the merger of a plurality of active devices, which share a common terminal, in a single dielectrically isolated (DI) island, or tub. In particular, an isolation groove is formed in the bottom of the DI tub and extends upwards toward the top surface of the semiconductor structure. The common diffusion region associated with the common terminal is located in the DI tub directly over the isolation groove. The isolation groove and common diffusion region thus separate the single DI tub into isolated sections, where a separate active device can be formed in each section. Isolation is achieved through the interaction of the groove with the common diffusion region to "pinch off" the conductive channel between devices in the DI tub. In a preferred embodiment, an inverted V-shaped isolation groove is utilized so as not to complicate the fabrication process. In order to merge a large plurality of devices in a single DI tub, a plurality of isolation grooves may be utilized to divide the single DI tub into a number of separate isolated sections.

    摘要: High voltage semiconductor devices include a drift layer region underlying a field gate electrode, the drift layer region having a selected charge density of lesser magnitude than the charge density of the remainder of the drift layer. This tailoring of the charge density of the drift layer region lowers the pinch-off voltage of a MOSFET inherent in the drift layer region. This lower pinch-off voltage decreases the potential of a device buried-layer when the device is in a reverse blocking mode of operation.
