Used DNK MA-4200 #293797494 for sale

DNK MA-4200 Mask Aligner is a sophisticated and highly precise tool for electrolithographic production of large-scale integrated circuits (LSIs). It is a fully automated, computer-controlled exposure unit specifically designed for use with wafer steppers and mask writers. DNK MA4200 mask aligner is equipped with an advanced mask pattern processor and an extremely capable optical alignment equipment, allowing for accurate and repeatable alignment of the mask to the substrate. It is also capable of automatically indexing individual layers and achieving high resolution alignment on all levels of integrated circuit layers. MA 4200 mask aligner offers numerous features for users to maximize productivity and quality. It is equipped with a resistive touch screen user interface, making the device easily accessible to inexperienced users. The user interface also includes a highly accurate alignment system with advanced zoom and panning capabilities, allowing for fine tuning of alignment parameters. Additionally, the unit is capable of thoroughly checking mask data in advance of exposure for accuracy and any errors in the mask patterns. The exposure process involves using the mask pattern data to direct the laser beam to the substrate's surface at extremely precise spots. This allows for making micro-circuits on the surface with a resolution of between 10 and 1 micron. The precision of the exposure process is further enhanced by the use of a dual piezoelectric stage, which can accurately move the substrate by 0.1 micron increments. MA-4200 mask aligner works using laser light with a wavelength of 248 nm and power of up to 480mJ per pulse. It has an exposure time as low as 0.2 seconds and can be operated at a maximum temperature of 40 degrees Celsius. MA4200 is compliant with all current safety standards and is equipped with an automatic fire extinguishing unit for extra safety. Not only does DNK MA 4200 mask aligner offer superior performance, but also provides the flexibility of using different substrates without the need for re-alignment. The unit comes with a nozzle exchange machine, where various substrates can be placed and automatically exchanged in seconds. Ultimately, the precise and automated manufacturing process offered by DNK MA-4200 makes it one of the most advanced and cost-effective mask aligners currently available.
