Used ASML PAS 5500 / 250C #293811101 for sale

ASML PAS 5500 / 250C is a highly advanced professional-grade wafer stepper designed for advanced semiconductor applications. It is used in the production of integrated circuits and other related microelectronic devices. The equipment is comprised of a number of components, including a mainframe, de-chuckers and chuckers, a computer control unit, an optical alignment system, wafer handling equipment, and motors and drives. The mainframe is responsible for controlling the entire unit, while the de-chuckers and chuckers and wafer handling robots handle the wafer transfers. The computer control unit is responsible for sending commands to each machine component and maintaining data for wafer loading/unloading, tool tuning, and calibration. The optical alignment asset is used to measure the position of the wafers with precision and accuracy, and consists of a motorized stage for alignment, two laser interferometers, a digital signal processor (DSP) for measuring misalignment, and a monitor. The wafer handling equipment consists of an elevator, an XY translation stage, and a cassette lift, all of which help to accurately position the wafer onto the wafer stages. The motors and drives are responsible for providing precise motion to the alignment motors, mainframe components, and wafer handling robots. The model offers a variety of features, such as a 50 mm field of view with 21 mm of wafer movement capability, a 7nm accuracy of what placement, and a 0.2 μm accuracy of what alignment. Additionally, it has a speed of up to 12 wafers per minute, and is capable of accommodating both 300 mm and 200 mm wafer sizes. PAS 5500 / 250C is capable of working in both batch and continuous production environments, providing a number of advantages over traditional wafer steppers, such as improved yield and efficiency, faster throughput, and more reliable operations. By providing numerous automated and semi-automated features, it is well-suited for high-volume production, ensuring that the process is completed in a timely manner and with the highest quality results.
