A semiconductor device according to the embodiment includes an element region provided with a transistor, a plurality of mixed crystal layers, a drain electrode and a source electrode, an element isolation layer and a dummy pattern. The mixed crystal layers are the layers made of a first atom composing the semiconductor substrate and a second atom having a lattice constant different from the lattice constant of the first atom and formed on both ends of a region, which becomes a channel of the transistor. The dummy pattern is a layer made of the same material as the mixed crystal layers and formed to extend on the surface of the semiconductor substrate and outside of the element region such that a major direction thereof is different from a direction of the semiconductor.

According to one embodiment, a heat treatment apparatus includes a light emitting unit to emit light to irradiate a wafer, a processing unit with a stage section and a control unit. The control unit implements a first irradiation to irradiate the light onto the wafer. After the first irradiation, the control unit changes at least one selected from a disposition of the wafer, a distribution of an intensity of the light on a major surface of the stage section along a circumferential edge direction of the wafer, and a distribution of a temperature of the wafer in a supplemental heating by the stage section along a circumferential edge direction of the wafer. After the changing, the control unit implements a second irradiation to irradiate the light onto the wafer. Durations of the first irradiation and the second irradiation are shorter than a time necessary for the changing.

In a small scaled plant intended for flexible manufacturing, a pure water supply system is provided at a low cost without reducing a production efficiency. A pure water system produces a plurality of grades of pure water which are supplied through pipes connected to points of use for cleaning, CMP, lithography, and the like. Upon receipt of a request signal from each point of use for starting to use a certain grade of pure water, a controller determines whether or not a required amount exceeds the capacity of the grade of pure water which can be supplied by the pure water system. If not, the controller sends a use permission signal to the point of use for permitting the same to use the pure water. When a certain use point is using the requested grade of pure water, the controller may not permit the requesting point of use to use the pure water until a use end signal is sent from the use point which is using the pure water.
