The Karl Suss MA6 is a high resolution semi-automated photolithography mask aligner designed for research and development, and small volume production. It is capable of handling irregularly shaped substrates ranging from 5 x 5 mm dies to wafers up to 150 mm. The maximum substrate thickness which can be processed is 6 mm. Resolution of 0.6 µm can be achieved under optimum conditions in vacuum mode. The splitfield microscope with capability of storage and automatic movement between reference points allow for highly accurate alignment to fiducials. Bottom-Side Alignment (BSA) allows for accurate alignment of features on the backside of the wafer to the photomask.
The tool has wide applications in semiconductor research, MEMS-development, microfluidics, and optical component production.
