Used DNS / DAINIPPON MA-4200 #9358769 for sale

DNS / DAINIPPON MA-4200 Mask Aligner is a advanced photolithography machine for the production of semiconductor devices. This advanced equipment features an auto-aligner, a high-accuracy moveable stage, and high-performance optics with a 5-inch exposure area. The auto-aligner measures the distortion between the stepper's field of view and the wafer itself, allowing for full 3D alignment of the mask and wafer. The system calibrates the air gap between the mask and the wafer surface to achieve an incredibly precise overlap of the two surfaces. The precision stage provides high-accuracy (+/- 0.001mm) movement with minimal subsidence and vibration, allowing for smooth operation and precision alignment of the mask and the wafer. The stage is completely motorized and completely automated, eliminating the need for manual adjustment. The unit is also equipped with two linear encoders to measure the x, y, and z-axes of the stage. The machine is also equipped with high-performance optics to guarantee the precise alignment of the mask and the wafer. This tool features advanced lens design, unlike earlier mask aligners, and offers excellent depth of focus and high resolution imaging. The asset uses three 4X/5X glasses to give the user an overall 5X aligning magnification, and it includes a variety of special masks and lenses for different application requirements.
