Used SVG / ASML 90S #9077807 for sale

SVG / ASML 90S is a computer-controlled photoresist equipment utilizing contact printing, designed to transfer a pattern in an exacting manner onto a silicon substrate. It is used in the production of microelectronic circuits. The system uses pattern shapes that have been stored on a computer and optically projected onto the substrate from a integrated optical column. The optical column holds a variety of lenses, such as focusing elements, imaging elements and projection elements. A mask is placed between the optical column and the substrate, which hold the circuit pattern. The light from the projection lens passes through the mask and is focused onto the substrate. When the light passes through the pattern on the mask, it is focused onto the photoresist-coated substrate. Depending on the type of photoresist material used, it will either be exposed to the light or be blocked from the light to determine the pattern in the photoresist. SVG 90S unit has a pattern generator to accurately reproduce the desired design onto the substrate. This machine also includes a close lattice interferometer, used to measure the focusing by comparing the two wavefronts of the projected and reflecting beams. This tool also includes a stage control unit for setting the accuracy of the stage movement, the orientation, and z-axis position. In addition, this asset has a laser scanner, which focuses laser light onto the substrate and uses it to adjust the stage's position with sub-micron precision. This ensures that the substrate can be accurately moved in order to maintain the positioning of the projected pattern. The substrate is then exposed with a UV light source and this is used to expose the photoresist. The exposed photoresist is then developed in a solvent and processed according to the manufacturer's instructions. The result is a circuit pattern on the substrate that is accurate and precise in its dimensions. The model also has a post-process integration tool that monitors the equipment's performance, ensuring that it is operating at its highest capacity. ASML 90S is essential in the manufacture of ultra-high density and high quality micro components, such as processors, microcontrollers and memories. It is one of the most accurate and reliable photoresist systems available on the market.
