Used DNK MA-4200 #9159261 for sale

DNK MA-4200 is an automated Mask Aligner designed for working with wafers up to 200mm. It features a Mask Positioner (MP) and an Alignment Microscope (AM) which can be used for precise alignment of various device structures on a wafer. Mask Aligners are commonly used in the microelectronics industry for photolithography processes. The Mask Positioner (MP) has an X-Y positioning system that moves the mask frame over the wafer. It is capable of automated alignment of the mask frame to the wafer with a resolution of 0.1μm. It is equipped with a synchronous motor and a high-resolution encoder for precise positioning. The Mask Positioner also allows for manual fine-tuning of the mask frame with the aid of the Alignment Microscope. The Alignment Microscope (AM) is an optical microscope with built-in laser diode and splash-proof view port. It is used to observe and align the mask frame on the wafer with nanometer-level accuracy. The Alignment Microscope has a 10x magnification and a resolution of 0.2μm. It is capable of aligning large-area substrates with the help of alignment targets. DNK MA4200 also includes a Camera Orientation Mechanism (COM), which is used to orient the camera for mask writing and other processes. The COM is equipped with a high-performance torque motor and sophisticated encoders, making it capable of highly accurate alignment of the camera over the wafer. In addition, the Mask Aligner is equipped with a high-power halogen illuminator, making it possible to generate uniform illumination over a large area. It features a built-in cooling system for enhanced mask writing performance, as well as a maintenance journal for tracking maintenance operations. MA 4200 is a reliable and efficient Mask Aligner with features that make it suitable for a wide range of photolithography process steps. It provides an excellent combination of precision, accuracy and performance, making it an ideal choice for high-quality microelectronics manufacturing.
