Semiconductor device using a silicon wafer with a pattern arrangement

摘要

A semiconductor device comprising: a support part; a flexible part, one end of which is supported by the support part; a spindle part supported by the other end of the flexible part; a displacement detection means which detects displacement of the spindle part; and an aperture part arranged adjacent to the spindle part; wherein a plurality of patterns comprised from the aperture part is formed on a silicon wafer parallel to a first direction and a second direction which intersects the first direction, the plurality of patterns include one or more patterns arranged in a straight line in the first direction and the second direction, the plurality of patterns is arranged so that an axis in which a cleavage plane of the silicon wafer and a surface arranged with the pattern on the silicon wafer intersect, and the first direction are different.
