GENERAL INFORMATION
The MA6 is designed for all standard lithography applications. Wafers and pieces up to 6" in size can be used. Masks up to 7" x 7" can be used. The system consists of a dual video microscope with two separate motorized fine focus drives and two CCD cameras.

EXPOSURE and OPTICS
The DUV exposure optics of the MA6 offers full field exposure down to 240 nm with a 1000W mercury lamp UV source. The system is equipped with micro-optics exposure for aberration reduction and highest uniformity.

The MA6 handles both proximity and (soft, hard, vacuum) contact printing, allowing for a resolution of 2.5 μm in proximity mode and sub-micron in vacuum contact mode. UV400, UV300, and UV250 filters are optional to use.

TOP and BACK SIDE ALIGNMENT
The MA6 is equipped with a motorized Topside Alignment System providing a high precision alignment accuracy of ± 0.5 μm. This mask aligner also has the capability of back side alignment with two special video microscopes and a special chuck for back side alignment.
