摘要： A method and apparatus for manufacturing a semiconductor physical quantity sensor according to the present invention achieves the high sensing accuracy and reliability and prevents a sticking phenomenon. Specifically, a semiconductor physical quantity sensor is cleaned by a displacement liquid and is dried while a SOI substrate is revolving. The number of revolutions is determined so that a suction force (Fs), which acts on a silicon substrate by a surface tension of the displacement liquid, a sensor spring force FK and a centrifugal force (Fr) generated by the acceleration in the revolution can satisfy the following condition: (FK+Fr)>FS. In order to prevent the sticking phenomenon after the stop of the spray, the semiconductor physical quantity sensor is dried by spraying an inert gas such as nitrogen including minus ions so that the revolving SOI substrate can eliminate static electricity generated by friction of the air flow.
