Used USI PV480 #9183256 for sale

USI PV480 is a mask aligner used for photolithography applications such as semiconductor device fabrication. It is a high-throughput machine employing laser interferometry with advanced edge recognition and accuracy control technology. PV480 mask aligner uses a linear motor as an underlying design, designed for finer alignment of large panel substrates over the course of longer exposure times. The mask aligner is also equipped with an integrated chuck table, which areas large enough to house both 6 and 8 inch wafers. This size enables USI PV480 to handle large substrates such as flat panel displays. PV480 computationally compensates for flatness variations by recognizing the edges of substrates and then synchronizing the laser's x, y and θ axes accordingly. This ensures the substrate remains perfectly aligned throughout processing time. Its edge recognition capabilities also detect contamination such as particles and dust, automatically correcting the substrates for a uniform exposure. USI PV480 offers an advanced Point to Point Algorithm for precisely scannning continuously and mapping precisely the position and angle of each exposure. It is able to deliver an exposure accuracy of +/-3μm over the entire field complexity of 600 x 600mm. PV480 features a durable xenon lamp with an output spectrum optimized for photolithography. Its low power consumption, low maintenance and advanced heat management technologies ensure reliable operation under high-volume production. USI PV480 mask aligner comes with an intuitive software package for recipe development, which includes tools to quickly program, adjust, monitor, control and troubleshoot the aligner from the user interface. It has a customizable mask editor to easily design and verify mask patterns. In conclusion, PV480 mask aligner is an advanced, high-throughput machine ideal for large-scale photolithography applications such as flat panel display production. With its edge recognition capabilities, uniform exposure correction and precise scanning capabilities, it is able to deliver high-resolution, accurate results with minimal variability.
