What it is

The JEOL ML2 is a maskless lithography system. The system uses a patented ZrO/W (Schottky) emitter.[1]

How it works

General reference — not yet source-verified

A maskless lithography system typically uses a focused electron beam that scans across a substrate coated with an electron-sensitive resist. The beam is deflected by electromagnetic lenses to trace the desired pattern. The resist is then developed, and subsequent etch or deposition steps define the final structures.
