发明名称 Vent hole sealing in multiple die sensor device
摘要 Embodiments of methods of fabricating a sensor device include attaching first and second die to one another to define first and second cavities in which first and second sensors of the sensor device are disposed, respectively. The second die has an opening in communication with the second cavity. The methods further include obstructing the opening, attaching a third die to the second die. The first cavity is hermetically sealed by attaching the first and second die. The second cavity is hermetically sealed by attaching the third die to the second die.
