Used ASML Twinscan AT 1100B #293817674 for sale

ASML Twinscan AT 1100B is a top-of-the-line wafer stepper, made by the semiconductor manufacturing equipment manufacturer ASML. This equipment is capable of producing extremely accurate patterns on the top surface of a silicon or other semiconductor wafer. The system is made up of a stage which holds the wafer in place, and three main moving components - the illumination unit, the objective lens, and the projection plate. The illumination machine is used to generate a completely uniform exposure of the pattern onto the wafer surface. This is done using three halogen lamps which have an adjustable height for different types of exposures, and provide a uniform intensity of light across the wafer. A Hollow Cathode Lamp is used to provide a stabilized, ultra-short exposure time for high-precision exposures with a minimum of thermal effects. The objective lens is used to magnify the image projected by the projection plate onto the wafer surface, so that the pattern created is accurate at the highest resolution. The lens has a variable numerical aperture and is capable of zooming from 1X-4X which allows for different types of patterns to be made on the wafer with maximum accuracy. The projection plate is beside the lens and is used to project the desired pattern onto the wafer surface. This plate contains an array of mirrors and the pattern is generated by four lasers, and 180 degrees of motion is enabled so that patterns can be created from a variety of angles. Unlike other wafer steppers, Twinscan AT 1100B has a layer exposure tool which ensures the optimum exposure of each layer without needing to move or tilt the substrate. This increases accuracy and allows for increased production speeds and cost efficiency. The asset is desktop in size, but is easily moved on wheels from one location to another. It is capable of producing extremely accurate patterns at resolutions above 0.5 um which are ideal for advanced integrated circuits. ASML Twinscan AT 1100B is a great choice for semiconductor device manufacturers looking for top-of-the-line wafer stepper systems.
