Used SQJ MDLAT 4000 ER #9388361 for sale

SQJ MDLAT 4000 ER is a stepper used in semiconductor and integrated circuit production. It is capable of producing high-resolution, three-dimensional wafers with extreme precision. It can produce wafers with numerous layers of intricate patterns with superb accuracy. Its operation is based on the principle of projection lithography, which involves projection imaging of a mask onto a target material. The mask is illuminated with a variable intensity beam, and the light exposing the target material is determined by a collimated light source. The angle, size and intensity of the light beam is adjustable to match the pattern of the mask. MDLAT 4000 ER has several features which maximize its precision and accuracy. Its Reticle Stage is capable of very high positional and angular accuracies, and the Reticle Demand Drive Unit effectively avoids vibration and stress irregularities in transport. The Motorized Reticle Alignment Clamps engages the reticles with a high force capacity, facilitating precise reticle location and alignment. SQJ MDLAT also features Automatic Collimator Calibration to rapidly adjust the light intensity and beam size, and lens mask coating to ensure an uninterrupted continuous layer of light exposure. It is also equipped with an intricate optical system and a highly-efficient detector array that can detect and process up to 64 million different pixels. The precision and versatility of SQJ MDLAT 4000 ER makes it a valuable tool for state of the art semiconductor production. It is capable of producing high-resolution wafers and integrated circuits requiring precise patterns with intense accuracy, meeting the demands of today's ever-evolving technology market.
