Used ASM D1 #9399288 for sale

ASM D1 wafer stepper is a state-of-the-art lithographic equipment used for the manufacturing of semiconductor integrated circuits. It is primarily utilized as a mask aligner for transferring two-dimensional circuit patterns onto the wafer for further processing. The stepper's unique design ensures precise alignment and exposes circuits to the mask pattern with a minimum of movement. D1 wafer stepper is capable of handling a variety of substrate sizes and is equipped with an advanced vision system that uses diffraction gratings and an elliptical strobe to correct for any misalignments. In addition, the vision system can detect any too-thin layers and adjust the light source to adhere to the optimal exposure time. ASM D1 wafer stepper can also process multiple layers in a single operation. It is able to work with a wide variety of materials, including photosensitive polymers, film, and glass, with a specialized movable platform controlling the wafer's orientation to the mask's pattern. The wafer is kept stationary during the exposure process, allowing for excellent stability and resolution. D1 wafer stepper's unique design also provides the convenience of interchangeable optics capabilities. To ensure highest quality of imaging, it is equipped with anti-reflection coating for the objective, a unique condenser system for controlling aberrations, an adjustable lens, and a multi-channel image sensor. In addition to its precision and accuracy, ASM D1 wafer stepper's convenient design enables its operations to remain consistent with minimal downtime and maximum uptime. The full rotatable stage and programmable motor feature help to increase the process speed while providing smooth, reliable, and consistent performance. Overall, D1 wafer stepper is an excellent lithography tool for high-volume semiconductor processes. Its robust design and reliable performance is well-suited for achieving high yields and ensuring precision, accuracy, and consistency in production.
