Used ASML PAS 5500 / 500 #293814112 for sale

ASML PAS 5500 / 500 is an advanced wafer stepper tool used for the fabrication of semiconductor devices. It is capable of producing highly precise microstructures for a variety of semiconductor components. This machine uses an alignment and imaging equipment to expose an ultraviolet light pattern onto a semiconductor wafer. It features a Variable Symmetry System (VSS), a powerful illumination unit that provides the flexibility to adjust factors such as the shape of the projected image, the size of the field of view and the type of photomask. The tool has four optical systems, each containing multiple lenses and a separate alignment machine. Each tool can be independently adjusted to provide a steady and repeatable alignment accuracy under different conditions. The asset also features a low-distortion projection lenses to ensure an accurate and consistent lithographic process. PAS 5500 / 500 also includes an advanced scanning model, which ensures high-resolution imaging for a variety of layout shapes, including over-sized fields, sub-fields and small geometries. It also utilises repeatable motion of the stepper to accurately track multiple fields of view. Furthermore, ASML PAS 5500 / 500 is equipped with a reliable vacuum clamping technology, which prevents wafer distortion during the exposure process. The tool also includes an integrated OCR readout equipment, enabling easy reading of multiple barcodes of each wafer to ensure quick, automated processing. In conclusion, PAS 5500 / 500 is a powerful and highly accurate waferstepper tool designed to meet the demands of modern semiconductor fabrication. Its advanced, high-resolution optical and scanning systems enable precise and repeatable lithographic production of fine features and accurate, reliable wafer clamping throughout the process.
