Abstract: A centrifuge screening system and method of testing MEMS devices using the system. The wafer level centrifuge screening system can include a base centrifuge system and a cassette mounting hub coupled to the base centrifuge system. The method can include applying a smooth and continuous acceleration profile to one or more MEMS components via the base centrifuge system. Each of the one or more MEMS components can have one or more MEMS devices formed thereon. The one or more MEMS components can be provided in one or more cassettes configured on the cassette mounting hub. The method can also include identifying one or more target MEMS components, which can include identifying stiction in one or more MEMS devices on the one or more MEMS components.

Abstract: A system for testing a device under a high gravitational force including a centrifuge with a rotating member and method of operation thereof. An operating power can be applied to a device, which can be coupled to the rotating member. The system can include a rotational control that can be coupled to the centrifuge. This rotational control can be configured to rotate the rotating member in response to a controlled number of revolutions per time period. The system can also include an analysis device for monitoring one or more signals from the device with respect to the controlled number of revolutions per time period. The analysis device can be configured to determine a stiction force associated with the DUT (Device Under Test) in response to the time-varying gravitational forces and to the one or more signals from the DUTs.

Abstract: A method for providing acceleration data with reduced substrate-displacement bias includes receiving in an accelerometer an external acceleration, determining the acceleration data with reduced substrate displacement bias in a compensation portion in response to a first and a second displacement indicators from a MEMS transducer, and, in response to substrate compensation factors from a MEMS compensation portion, outputting the acceleration data with reduced substrate displacement bias, wherein the first displacement indicator and the second displacement indicator are determined by the MEMS transducer relative to a substrate in response to the external acceleration and to a substrate displacement, and wherein the substrate compensation factors are determined by the MEMS compensation portion relative to the substrate in response to the substrate displacement.
