The p-type FinFET includes a second germanium fin over the substrate; a second gate dielectric on a top surface and sidewalls of the second germanium fin; and a second gate electrode on the second gate dielectric. Methods of making such a display are also described. The indicator member may pivot about the axis when the box structure is filled with a liquid. A processor receives temperature data from a first set of temperature sensors.
