Abstract
In a packaging structure for a microelectromechanical-system (MEMS) resonator system, a resonator-control chip is mounted on a lead frame having a plurality of electrical leads, including electrically coupling a first contact on a first surface of the resonator-control chip to a mounting surface of a first electrical lead of the plurality of electrical leads through a first electrically conductive bump. A MEMS resonator chip is mounted to the first surface of the resonator-control chip, including electrically coupling a contact on a first surface of the MEMS resonator chip to a second contact on the first surface of the resonator-control chip through a second electrically conductive bump. The MEMS resonator chip, resonator-control chip and mounting surface of the first electrical lead are enclosed within a package enclosure that exposes a contact surface of the first electrical lead at an external surface of the packaging structure.
