Abstract
The present invention discloses a gas pendulum style level posture sensing chip and its manufacturing method and a level posture sensor. The gas pendulum style level posture sensing chip includes: a semiconductor substrate; two sets of arm thermosensitive fuses formed on the surface of the semiconductor substrate, each set of the thermosensitive fuses including two thermosensitive fuses in parallel to each other, the two sets of thermosensitive fuses being vertical to each other; electrodes formed at the two ends of the thermosensitive fuses. For the level posture sensing chip and sensor provided by the present invention, the parallelism and verticality of the thermosensitive fuses is high in precision such that the more accurate measurement can be implemented.
