Contact lithography exposes an entire substrate at once while the mask is in contact with the substrate. It is generally good for features down to about one micron and one micron overlay, but most people switch to the stepper for ease of achieving the smaller dimensions and tighter overlay. The Nanofab has two contact lithography tools, the EVG 620 and the Karl Suss MA/BA6, to satisfy demand for this basic lithography method. The Nanofab has the ability to make the contact masks as well.
Resolution 1 µm, Overlay 1 µm
