    摘要： The present invention relates to a semiconductor device having an integrated metal shield. The shield, created as part of a MOSFET, is formed about a gate electrode of the MOSFET to effectively reduce drain-to-gate capacitance and increase breakdown voltage. The shield consists of a metallic shield contact via and a source contact extension. The metallic shield contact via, formed between the gate electrode and a drain region of the MOSFET, may be either a series of closely spaced vias or a wide continuous via. The metallic shield contact via is isolated from the surface of a semiconductor wafer by a shield isolation layer at one end. The metallic shield contact via is electrically coupled to the source contact extension at the other end. The source contact extension is metallic, and may be formed from the same metal used to create a source contact and a drain contact for the MOSFET.

    摘要： The present invention includes a silicon-on-insulator (SOI) wafer that enhances certain performance parameters by increasing silicon device layer and insulator layer thicknesses and increasing silicon handle wafer resistivity. By increasing the silicon device layer thickness, effects of the floating body problem may be significantly reduced. By increasing the insulator layer thickness and the silicon handle wafer resistivity, influences from the silicon handle wafer on devices formed using the silicon device layer may be significantly reduced. As a result, standard tools, methods, and processes may be used.

    摘要： The present invention relates to using an insulator layer between two metal layers of a semiconductor die to provide a micro-electromechanical systems (MEMS) device, such as an ohmic MEMS switch or a capacitive MEMS switch. In an ohmic MEMS switch, the insulator layer may be used to reduce metal undercutting during fabrication, to prevent electrical shorting of a MEMS actuator to a MEMS cantilever, or both. In a capacitive MEMS switch, the insulator layer may be used as a capacitive dielectric between capacitive plates, which are provided by the two metal layers. A fixed capacitive element may be provided by the insulator layer between the two metal layers. In one embodiment of the present invention, an ohmic MEMS switch, a capacitive MEMS switch, a fixed capacitive element, or any combination thereof may be integrated into a single semiconductor die.

    摘要： The present invention relates to providing a uniform operating environment for each of multiple devices by providing a common environment to the devices. The common environment is provided by multiple cavities, which are interconnected by at least one environmental pathway, which may be provided by at least one tunnel. The common environment may help provide uniform operating pressure, which may be a partial or near vacuum, a surrounding gas of uniform contents, such as an inert gas or mixture of inert gases, or both. The devices may include micro-electro-mechanical system (MEMS) devices, such as MEMS switches.

    摘要： The present invention provides a MEMS switch that is formed on, not merely placed on, a semiconductor substrate of a semiconductor device. The basic semiconductor substrate includes a handle wafer, an insulator layer over the handle wafer, and a device layer over the insulator layer. The device layer is one in which active semiconductor devices, such as transistors and diodes, may be formed. The MEMS switch is formed over the device layer during fabrication of the semiconductor device. Additional layers, such as connecting layers, passivation layers, and dielectric layers, may be inserted among or between any of these various layers without departing from the essence of the invention. As such, the present invention avoids the need to fabricate MEMS switches apart from the devices that contain circuitry to be associated with the MEMS switches, and to subsequently mount the MEMS switches to modules that circuitry.
