For the ,Cr mask fabrication,, it has only two steps: (1) nanoimprint with a double layer resist (145nm thick UV resist on top of 250nm lift-off layer), and (2) deposition and lift-off ,Cr, of 160nm thick. Since it is very difficult to dry etch a thick ,Cr, layer to form ∼100nm patterns, a lift-off method is

A 0–180° phase edge on a ,mask, will print as a narrow dark line. An array of these edges will print patterns of lines and spaces with widths as low as 0.25λ/NA. Common types of PSMs are alternating (pictured here) and attenuated PSMs. Practical implementation of PSMs is limited by phase termination problems and ,mask fabrication, difficulties.

A number of characteristics make chromium a popular contrast medium for high-quality ,mask fabrication,: - excellent adherence to glass and silica substrates; ... The contact must last for a few seconds (5") and then opened. At this point the ,mask, remains in the solution, while the aluminium electrode can be taken out of the bath.

It will take about 3 – 5 minutes to cool to room temperature.

Etching (microfabrication) - Wikipedia

Etching is used in microfabrication to chemically remove layers from the surface of a wafer during manufacturing. Etching is a critically important process module, and every wafer undergoes many etching steps before it is complete. For many etch steps, part of the wafer is protected from the etchant by a "masking" material which resists etching.
