In a semiconductor-device fabrication method, a plurality of recessed portions are first formed in the principal surface of a substrate. Each pool cover hanging device includes a rim engaging element including a pool wall abutting portion, a horizontally adjustable member coupled to the pool wall abutting portion at a first end, and a vertically adjustable connecting member coupled to the horizontally adjustable member. When the subject is shot, location information of the subject is obtained from a radio signal transmitted by a marker which has been provided at the subject in advance. The 13 MHz, 9-level digital output signal may be further processed to generate a 6. The hydrate has a defined number of moles of water of crystallization and possesses better storage stability and dissolution characteristics than conventionally produced hydrates of such acid addition bis-salts. A semiconductor device that has a number of CMOS circuits and a number of MEMS is formed on the same semiconductor wafer in adjacent regions on the wafer, and then diced such that the CMOS circuits and the MEMS are formed on the same die.
