Used KARL SUSS / MICROTEC MJB-3 #293618665 for sale

KARL SUSS / MICROTEC MJB-3 is a high-precision mask aligner that is used in the manufacture of semiconductor and display devices. The machine is designed to align precise masks to the exact coordinates of a substrate with a high degree of accuracy and repeatability. The machine can handle a variety of substrates and wafers, including crystalline silicon, glass, plastic, or metal in sizes up to 13 inches in diameter. MICROTEC MJB3 mask aligner consists of the main control unit, two mask stages, two substrate stages, two x-ray flux intensity measurement systems, and imager heads. The main control unit contains all of the electronics for controlling and monitoring the various functions of the machine. The two mask stages are used for precision alignment of the photomasks to the substrate. The two substrate stages are used to securely hold the substrate in place and facilitate precise alignment. The two x-ray flux intensity measurement systems measure the intensity of the x-ray within the unit in order to ensure accurate alignment. Finally, the imager head is used to view the substrate and photomask under UV illumination. KARL SUSS MJB 3 offers a high degree of repeatability for Alignments accuracy up to an incredible 20 nanometers. This is accomplished through the use of two precision laser interferometers and a high-resolution stepper motor. The laser interferometers measure the distance between the photomask and the substrate, while the high-resolution stepper motor ensures that each alignment point is precisely achieved. MICROTEC MJB 3 machine has several advanced features, including automatic wafer mapping and wafer alignment scan, auto-focus capability, full x-ray inspection capabilities, and optimization and characterization tools. The x-ray inspection capability is particularly useful in ensuring that the masks are accurately aligned before they are transferred to and mounted on the substrate. The optimization and characterization tools provide a wide range of options for determining the exact alignment of each photomask on the substrate. Overall, MJB3 mask aligner is a highly sophisticated and precise machine for the accurate alignment of photomasks to substrates. By offering a high degree of repeatability and advanced features, KARL SUSS MJB 3 is an excellent choice for those in the semiconductor and display device industry who need reliable and precise mask alignment.
