Used ASML PAS 2500 / 30 #9241931 for sale

ASML PAS 2500 / 30 wafer stepper is a piece of equipment used in semiconductor fabrication processes to expose patterns onto the surface of integrated circuit (IC) substrates. It is a precision device capable of accurately and consistently printing circuit features onto a silicon wafer with extreme accuracy. PAS 2500 / 30 is an advanced stepper design that utilizes optical reduction techniques to accurately expose the desired pattern on a silicon wafer. The stepper is configured with two control systems, an outer equipment, and an inner system. The outer unit is responsible for cleanroom management, exposing the wafer to controlled processes, and maintaining precise alignments and accuracy. The inner machine is responsible for fine tuning the exposure of the wafer. This tool monitors and regulates the pattern fidelity, alignment, and the processes required to achieve the desired feature size. ASML PAS 2500 / 30 utilizes a variety of optics and a step-and-repeat approach. The optics array consists of multiple lenses, filters, and other components that are all precisely aligned to direct the input pattern onto a silicon wafer. This optical array is combined with a step-and-repeat approach to accurately expose the wafer patterns. The stepper cycles the focused pattern and carrier through index increments and steps the entire field at a fixed number of times per cycle. This helps ensure accurate pattern exposure. The stepper's outer asset monitors the atmosphere and light shielding of the wafer overlay and can control the ambient conditions, such as temperature and air pressure. This helps to ensure that the exposure of the wafer is exactly as specified on the pattern layout. Additionally, PAS 2500 / 30 includes a set of precision testing and metrology tools that can be used to monitor and measure the performance of the stepper. These tools can provide data related to exposure, alignment, and performance of the stepper, and help to identify any potential issues with its operation. Overall, ASML PAS 2500 / 30 is a highly sophisticated and accurate wafer stepper designed for semiconductor fabrication processes. It is capable of exposing patterns onto a silicon wafer with extreme accuracy, allowing for the production of high-quality integrated circuits. This stepper is a valuable piece of equipment for any modern semiconductor fabrication facility.
