A semiconductor device comprises a substrate, a mounting chip, multi-stage bumps, and a sheet-like interposer member. An object name is assigned a directory entry which includes first information data as a reference to the automation object; second information data as a description of technological functionality; and third information data as a description of interfaces of the automation object. , one that does not require a magnetic field to reverse the magnetization in the magnetic recording media, uses a FeMnPt L10 alloy as the magnetic media. The valve body is configured with an aperture that is aligned with the fluid passage in a first and second operating state, one of which decouples the fluid circuit from the system.
