摘要:
A device (20) includes sensors (30, 32, 34) that sense different physical stimuli. Fabrication (90) entails forming (92) a device structure (22) to include the sensors and coupling (150) a cap structure (24) with the device structure so that the sensors are interposed between the cap structure and a substrate layer (28) of the device structure. Fabrication (90) further entails forming ports (38, 40) in the substrate layer (28) such that one port (38) exposes a sense element (44) of the sensor (30) to an external environment (72), and another port (40) temporarily exposes the sensor (34) to the external environment. A seal structure (26) is attached to the substrate layer (28) such that one port (40) is hermetically sealed by the seal structure and an external port (46) of the seal structure is aligned with the port (38).
