Used SCREEN RF-300A #9355372 for sale

SCREEN RF-300A is a state-of-the-art wafer stepper manufactured by SCREEN Semiconductor Solutions. It is designed to efficiently and accurately map patterns onto semiconductor substrates to create highly integrated circuits such as memory chips, analog and digital ICs, and high performance logic circuits. This advanced wafer stepper is equipped with an advanced alignment equipment that provides sub-micron accuracy, enabling the advanced fabrication of circuit patterns with miniscule features, high density, and consistent consistency. RF-300A utilizes a stepped laser beam and a high power laser exposure to accurately map circuit patterns on the substrate. This pattern exposure can be done in a single step or multiple step process, allowing for exposure in either a full field or in predefined areas. The advanced stepper then uses a high-precision optical microscope to optically align the circuit design onto the substrate. This optical alignment process is done in two steps: a coarse alignment, which is achieved by shifting the already exposed mask to match a chosen reference point, and a fine alignment, which is achieved by superimposing the imaging pattern onto the substrate. This multiple-pass process ensures accurate placement of the circuit design onto the substrate and helps maintain the pattern definition throughout the entire manufacturing process. In addition, SCREEN RF-300A is equipped with a high resolution vision system that eliminates the need for full-field imaging of the substrate to properly align the circuit design. Additionally, its state-of-the-art photomask provides an optimal pattern coverage for high power exposure, which helps reduce manufacturing costs. Finally, RF-300A also includes a sophisticated programmable controller which allows operators to set up and adjust parameters, such as pattern exposure times and calibration settings, with ease. Overall, SCREEN RF-300A wafer stepper is a highly advanced manufacturing tool capable of producing intricate and precise circuit patterns with excellent accuracy, repeatability, and throughput. Moreover, its many cutting-edge features, such as its alignment unit, vision machine, and photomask, make RF-300A an invaluable tool for semiconductor fabrication and a must-have for any high-tech production facility.
