A layer of doped or undoped germanosilicate glass is formed on a substrate and the layer of germanosilicate glass is thermally treated in steam to remove germanium from the germanosilicate glass, and thereby raise the reflow temperature of the germanosilicate glass so treated. The historical execution data is dynamically updated based on query execution performance. With an arranged relationship between the pointer units and cylindrical lens, two beam fluxes from respective units cross each other at a point where the cylindrical lens is arranged, wherein the beam fluxes are at right angles to the central axis of the cylindrical lens. The first media server may also be coupled to a third media server over the network. Metal is then formed in the openings, which may include the cutout regions. The first and second PMOS and first and second NMOS transistor devices form a cross-coupled transistor configuration.
