Semiconductor devices are provided such as, ferroelectric transistors and floating gate transistors, that include an epitaxial perovskitedoped strontium titanate structure formed above a surface of a semiconductor substrate. The case has a sensing unit housing portion and a pipe portion that extends from the sensing unit housing portion in a form of a pipe. The curved display system has a curved material having an outer surface, an inner surface, and a radius of curvature similar to a mechanical reel. The graphical representation is displayed using a display device coupled to the at least one computer. The first flow rate is substantially lower than the second flow rate. No DUT alignment members are used on the test board or socket that limit the physical proximity of the DUT to its preferred test position with respect to the test circuit.
