Used SEMITOOL 870S #9397638 for sale

SEMITOOL 870S is a photoresist equipment used for the processing and manufacturing of electronic devices. It is a mask aligner, an instrument used for creating patterns on a flat substrate layer. Photoresists are light-sensitive materials that react where a beam of light passes through, allowing for patterning of certain areas. SEMITOOL 870 S consists of an automated table for loading and unloading the substrate materials, an exposure source and a stepper. The exposure source features a fixed transparent surface and quartz illuminator, which enables the desired pattern to be exposed onto the resist layer using photoexposure. The stepper allows precise positioning of the exposure source and motion of the substrate table in both the x and y directions. 870S system is equipped with software which allows for specific pattern definition. Since the patterns are created with the exposure source, exact positioning is required. This can be achieved by the automatic features of the unit, with the 6-axis controls supplying movement of the exposure source in X, Y and Z directions, pitch, roll and yaw for perfectly jogged alignment of the mask. 870 S also includes a High Rate Metal Cleaning feature, allowing for resist removal and metal particles etching on the substrate. This is done at a high rate, with the use of a high-power pulsed laser. This powerful laser provides fast and precise resist exposure, thus making SEMITOOL 870S machine suitable for advanced applications. Overall, SEMITOOL 870 S is an efficient photoresist tool designed to provide accurate patterning of electronic devices. It is user-friendly, with its automated loading and unloading capabilities, precise positioning, software-defined patterns, high rate metal cleaning and the use of a high-power laser for exposure. 870S is thus a useful tool for manufacturing and processing electronic devices.
