Used ASML 250 #293760307 for sale

ASML 250 is a wafer stepper equipment employed in the semiconductor manufacturing industry as a tool for photolithographic pattern transfer from a photo mask to a substrate or "wafer". 250 is a 242 nm scanner system, capable of a field size of ASML 250 mm, that uses optical imaging to transfer the desired pattern onto a lower substrate. The unit consists of an illuminator, pattern generator, scanner, wafer stage, and the controller. The illuminator produces a highly focused and highly intense light beam which is used to illuminate the photo mask that holds the desired pattern onto the wafer. The pattern generator creates a field of evenly distributed photons that act as a medium for the mask to transfer its pattern onto the wafer. The scanner rotates the wafer relative to the pattern generator, thereby equalizing any potentially non-uniform irradiant intensity across the field. The scanner is also responsible for providing specific movements for alignment and joining of the photo mask and wafer. The wafer stage is the platform for holding the wafer in place throughout the exposure and alignment process. The precision across the wafer stage is maintained by a pneumatic air bearing machine, providing a unique combination of inertia, stiffness, and damping desired. Finally, the controller is the "brain" of the tool, providing the user interface, data control, path control, and other features to customize the user's needs. All these components work together to accurately and effectively transfer the desired pattern onto the wafer. The high stability, accuracy, and fast throughput of ASML asset make it an ideal tool for the intensive and precise volume manufacturing of multiple microchips, nanotechnology, and other IC devices. Utilizing the auto-alignment and focus control features of the model, the user is further able to leverage the advanced features of 250 to increase the yield and maintain desired quality in their production. The combination of ease-of- use, high accuracy, and throughput speed of the equipment make ASML 250 an ideal choice for microchip manufacturing of various applications.
