摘要:
A position detecting device, usable in a projection exposure apparatus for optically projecting a pattern of a reticle upon a wafer by use of a projection lens system, for detecting the position of the wafer with respect to an imaging plane of the projection lens system is disclosed. The position detecting device includes a light source from which light is projected upon the surface of the wafer. The light reflected by the wafer surface is converted by a photoelectric converting element into an electric signal, on the basis of which the position of the wafer is detected. Upon the projection of the position detecting light, the light is controlled by an optical integrated-circuit such as an optical waveguide type element. This allows, with a simple and compact structure, the irradiation of the wafer surface with lights of different wavelengths from plural light sources and/or the irradiation of different locations on the wafer surface with the light.

Image signals input via input terminals are selected by a selector. The selected image signals are combined and displayed on the same screen of a display device. The display screen includes one main screen and a plurality of sub screens. In the case where a moving image is displayed on the main screen, images displayed on the sub screens are updated when the moving image displayed on the main screen are in a still state. The modes of the image signals are detected only when they are input for the first time, the process performed upon the image signals input after that is controlled in accordance with information stored in a memory.

摘要:
The present invention concerns a method for fabricating a nanowire thermoelectric device comprising the step of providing a substrate upon which to form nanowires. The substrate comprises substrate electrodes passing from a top exposed surface of the substrate to a bottom exposed surface of the substrate. Another step involves forming a first electrode pattern, which forms first and second electrically connected groups of substrate electrodes, on the bottom surface of the substrate. A p-type nanowire is then formed on the substrate by activating the first group of substrate electrodes during p-type material deposition. Similarly, a n-type nanowire is formed by activating the second group of substrate electrodes during n-type material deposition. And top electrodes are formed to connect the p-type and the n-type nanowires and a second electrode pattern is formed on the bottom side of the substrate to replace the first electrode pattern to form a thermocouple.
