Yes, you can after approval. Email your request along with a copy of the materials SDS to the cleanroom manager (Maya).
In most cases, yes, the photoresist is still good. Manufacturers often apply expiration dates well under a date when the photoresist might start exhibiting performance issues. Photoresist is often good for several years after the posted expiration date. The most common source of photoresist going “bad” is water condensation which is often the result of opening the photoresist bottle while cold; straight out of the refrigerator. To reduce this possibility, always allow the photoresist to warm to room temperature before pouring or opening the bottle to use at the spin bench. Ultimately, test the photoresist on a dummy sample if you are concerned.

It depends. For activities such as waiting for a vacuum pump down, or a temperature setpoint (CVD01) or cooldown, yes, you may step away from the tool or leave the cleanroom. Once you start your process, ie: evaporation or plasma (deposition or etch), you are required to remain with the tool.
