Abstract: A MEMS device and method of making same is disclosed. In one embodiment, a micro-switch includes a base assembly comprising a movable structure bearing a contact pad. The base assembly is wafer-scale bonded to a lid assembly comprising an activator and a signal path. The movable structure moves within a sealed cavity formed during the bonding process. The signal path includes an input line and an output line separated by a gap, which prevents signals from propagating through the micro-switch when the switch is deactivated. In operation, a signal is launched into the signal path. When the micro-switch is activated, a force is established by the actuator, which pulls a portion of the movable structure upwards towards the gap in the signal path, until the contact pad bridges the gap between the input line and output line, allowing the signal to propagate through the micro-switch.

Abstract: Improved microelectromechanical systems (MEMS), processes and apparatus using thermocompression bonding are disclosed. For example, process embodiments are disclosed in which wafer-scale as well as die-scale thermocompression bonding is utilized to encapsulate MEMS and/or to provide electrical interconnections with MEMS. Apparatus embodiments include apparatus for performing thermocompression bonding and bonded hybrid structures manufactured in accordance with the process embodiments. Devices having various substrate bonding and/or sealing configurations variously offer the advantage of reduced size, higher manufacturing yields, reduced costs, improved reliability, improved compatibility with existing semiconductor manufacturing process and/or greater versatility of applications.
