Mask Alignment System

The EVG®610 is a compact and multi-purpose R&D system that can handle small substrate pieces and wafers up to 200 mm.

The EVG610 supports a variety of standard lithography processes, such as vacuum-, hard-, soft-, and proximity exposure modes, with the option of back-side alignment. Moreover the system offers additional capabilities including bond alignment and nanoimprint lithography (NIL). The EVG610 offers quick processing and re-tooling for changing user requirements with a conversion time of less than a few minutes. Its advanced multi-user concept can be adapted from beginners to expert level, thus making it ideal for universities and R&D applications.
