Why are Roughing Pumps Important in Nanotechnology?
In nanotechnology, the creation of nanoscale structures often requires a high-vacuum environment to prevent contamination and ensure the purity of materials. Roughing pumps serve as the first stage in the vacuum creation process, bringing the pressure down to a level where high-vacuum pumps can take over. This is particularly important in processes such as atomic layer deposition (ALD) and chemical vapor deposition (CVD).
