Used ASML AT 1200 #9293661 for sale

ASML AT 1200 is a type of wafer stepper used in the manufacture of integrated circuits. It uses photolithography to create the patterns on the wafer that will then be used to form the various components of the integrated circuit. The equipment consists of a stationary arm, which holds the substrate, and a movable arm, which carries the photomask or reticle used to transfer the required patterns onto the wafer. ASML AT-1200 utilizes a pattern generator that uses a series of light-sensitive detectors to accurately control the position of the reticle. The entire system rests on a closed loop servo unit which accurately moves the arms. This allows the device to quickly scan the reticle across the wafer to accurately transfer the image. To ensure that the images are accurately transferred to the wafer, AT 1200 includes a through-the-lens-inspection (TTL) machine. This consists of an imaging camera that is positioned in front of the projection tool. As the pattern is scanned onto the wafer, the imaging camera inspects the pattern for accuracy. If any inaccuracies are found, they will be automatically corrected through the intelligence of the asset's control software. AT-1200 utilizes a variety of scanning methods, including row scan, 270-degree scan, and vector scan. Depending on the complexity of the circuit design, different scanning techniques will be used to ensure the highest levels of accuracy. To ensure that the patterns are accurately and consistently transferred to the substrate, ASML AT 1200 also includes a programmable exposure monitor and a digital image processor. As with other ASML steppers, ASML AT-1200 includes a range of diagnostics and maintenance tools to help technicians identify and repair any issues with the machine in a timely manner. The model also offers users varying levels of automation, from manual to fully automated wafer processing. Overall, AT 1200 is an advanced and versatile wafer stepper that offers manufacturers a variety of scanning and imaging options for integrated circuit design. Its closed loop servo equipment, TTL system, and programmable exposure monitor ensure accurate and consistent transfer of patterns to the substrate. The unit also offers a range of maintenance and diagnostic tools to keep the machine in peak operational condition. With all these features, AT-1200 is an ideal machine for the manufacture of integrated circuits.
