A hydraulic fluid flow management system and method includes three subsystems. This device comprises PMOS TFTs producing only a small amount of leakage current. The operation also includes assigning a color scheme to the process steps depending on the importance of the steps to an enterprise and transmitting a signal to display agent performance data based on the color scheme and indicative of steps missed by the first agent. The electron wave function and the hole wave function are substantially overlapped within a predetermined spatial region of the quantum well region.
