Used ULTRATECH 2244i #293761742 for sale

ULTRATECH 2244i Wafer Stepper is an advanced lithography stepper used in semiconductor manufacturing. It offers unparalleled precision, accuracy and throughput for etching, dep dosaging and other microlithographic processes. 2244i is capable of producing feature sizes down to 5 nanometers and provides a maximum reduction ratio of 1:64. It is a two-stage stepper, meaning that it uses two refractive lenses mounted in a tube in order to reduce the size of the pattern applied to the wafer. This allows for increased resolution, allowing for higher precision patterns. ULTRATECH 2244i utilizes a 2.5Kw Xenon arc lamp for its illumination source, which is also equipped with an auto-aligning quadrant shutter for effective pattern positioning. Additionally, the system has an acousto-optic laser pattern generator, which enables the device to quickly create accurate patterns with reduced exposure times. The system offers an impressive scan rate of up to 10,000 wafers per hour and a max shot size of several thousand microns per second, enabling it to process large amounts of wafers quickly and accurately. Furthermore, the system also offers customizable illumination settings and exposure levels such that exact feature inversion can be achieved consistently. In terms of maintenance, 2244i offers built-in diagnostic and calibration systems, meaning there is no necessity for a technician to be present to service the machine. It is also designed with a high degree of reliability, with a MTBF (mean time between failures) rate of up to 5 million cycles. In conclusion, ULTRATECH 2244i Wafer Stepper is an advanced lithography stepper optimized for microlithographic reactors such as etching and dosaging. It offers unparalleled precision and accuracy, with cutting-edge technology such as a 2.5kw Xenon arc lamp and an acousto-optic laser pattern generator. Additionally, it is designed for maximum reliability with a high MTBF rate, and maintenance is made easy with built-in diagnostic and calibration systems.
