Used NIKON NSR 1755 G7A #9159079 for sale

NIKON NSR 1755 G7A is a high-precision wafer stepper designed for advanced lithography processes. It is a fully automatic, single-lens, scanner-type projection equipment that enables quick step-and-repeat without the need for any manual alignment. The system utilizes a 0.75-NA, deep-UV illumination source for cost-effective lithography and is aimed at advanced 65 nanometer (nm) production. NIKON NSR-1755G7A projection unit consists of three main components: the optics, the camera, and the illumination source. The optics machine incorporates two lenses, the projection lens and the imaging lens, which enable accurate and precise focusing of the image, and uses the Deep Ultra-Violet (DUV) illumination to image the chip. The camera projects the image onto a 4-inch reticle image plane, enabling the use of conventional 4-inch mask reticles. The illumination tool of NSR-1755 G7A wafer stepper is a variable-numerical aperture (V-NA) unit, allowing for a large depth of field and a wide field of view due to the computer's control of the aperture. The illumination source is a two-amp, source-and-ring-type asset, designed to facilitate the projection of minute circuit details onto a 4-inch reticle. It also features a vacuum-tight stage structure that eliminates the need for an external venting pipe. NSR 1755 G7A wafer stepper uses three-dimensional automated focus control technology to ensure precise layer-by-layer registration of data onto the wafer. It features a high-accuracy and fast-response stage, which allows for quick and accurate positioning of the wafer in the exposure area. The model also has a built-in alignment mirror which eliminates the need for manual alignment of reticles. Finally, the equipment has a high-precision camera tracking system, providing fast and accurate registration of the wafer exposure data. Overall, NSR-1755G7A is an advanced and efficient wafer stepper with a wide range of features that enable fast, accurate and reliable production of advanced 65nm lithography devices. It is well-suited for production of LED and semiconductors, as well as any other products requiring precise and accurate lithography processes.
