Patterns on nine glass slides, set onto a silicon wafer which has been spin-coated with a polymer resin, ready for electrobeam lithography.
After electrobeam lithography the glass slides are removed from the wafer and a developer is used to remove the polymer strands cut by the laser, to reveal the pattern. There are so many different kinds of tweezers in this room.
Paul and I review the resulting patterns on the scanning electron microscope (SEM)
One of the new patterns - each dot is 70 nanometers in diameter : that's 0.00007mm (!)
