摘要: A linear accelerometer is provided having a support substrate, fixed electrodes having fixed capacitive plates, and a movable inertial mass having movable capacitive plates capacitively coupled to the fixed capacitive plates. Adjacent capacitive plates vary in height. The accelerometer further includes support tethers for supporting the inertial mass and allowing movement of the inertial mass upon experiencing a linear acceleration along a sensing axis. The accelerometer has inputs and an output for providing an output signal which varies as a function of the capacitive coupling and is indicative of both magnitude and direction of vertical acceleration along the sensing Z-axis. A microsensor fabrication process is also provided which employs a top side mask and etch module.

摘要: A process of forming a capacitive audio transducer, preferably having an all-silicon monolithic construction that includes capacitive plates defined by doped single-crystal silicon layers. The capacitive plates are defined by etching the single-crystal silicon layers, and the capacitive gap therebetween is accurately established by wafer bonding, yielding a transducer that can be produced by high-volume manufacturing practices.

摘要: A computer-implemented system for developing, tracking and managing legal (and other professional services) projects or matters through the Legal Project Management (LPM) process. The LPM process divides the management of a legal matter or project into three phases: Project Development; Project Execution; and Project Closure. The Project Development Phase includes conflict screening, fee arrangements, identification of the nature and scope of the matter, the goals of the stakeholders, the tasks associated with the matter, and development of a schedule, budget, and a communications plan. The Project Execution Phase involves monitoring the progress of the matter, tracking the actual time and cost to budget, identifying risks and changes to the scope of the matter as they develop, and communicating among team members. The Project Closure Phase includes file closure procedures, and team and client meetings to identify lessons learned in the engagement for future improvement.

摘要: A method for making a subsurface electrical contact on a micro-electrical-mechanical-systems (MEMS) device. The contact is formed by depositing a layer of polycrystalline silicon onto a surface within a cavity buried under a device silicon layer. The polycrystalline silicon layer is deposited in the cavity through holes etched through the device silicon and reseals the cavity during the polycrystalline silicon deposition step. The polycrystalline silicon layer can then be masked and etched, or etched back to expose the device layer of the micromachined device. Through the layer of polycrystalline silicon, a center hub of the device may be electrically contacted.

摘要: The present invention involves an electrical verification method that detects moisture within the cavity of the semiconductor or micro-machined device. The method affects an increase in the time for sufficient water vapor to remain within an unsealed device, so that instability in the diode can be measurable over a longer period of time. The method begins with the step of forming at least one reservoir on at least one of the device wafer and the capping wafer. The at least one reservoir connects to at least one diffusion channel, which is in communication with at least one reservoir port. The method further includes the steps of forming a PN junction diode adjacent to the at least one reservoir port; bonding the device wafer with the capping wafer to form a cavity; and electrically testing the PN junction diode as an indication of the presence of moisture within the cavity. The device assembly of the present invention includes a capping wafer bonded on a device wafer to form a cavity; at least one reservoir including at least one diffusion channel for receiving a liquid and retaining moisture. The at least one diffusion channel communicates with at least one reservoir port, which is open into the cavity. An exposed PN junction diode is provided adjacent to the at least one reservoir port, and a pair of metal pads is connected to the exposed PN junction diode.
