The technician that works in the semiconductor, micro-electromechanical system and nano technologies manufacturing sector must work with various pressure ranges that are below atmospheric pressure. A technician experienced in vacuum technology is reviewing previous test data conducted on a single stage vacuum pump and a two-stage vacuum pump that she is now responsible for. The tech expects the two-stage pump to “pull” a better vacuum that a single stage pumps. That same technician also understands the concepts of outgassing and a vacuum leak. The tech is very knowledgeable, understands the operation of the pumps under test and has reviewed the data plots shown below very carefully.
