    The quality of backside cooling is estimated through the helium leak rate. For an electrostatic clamp (ESC) a helium leak up rate below 30 mtorr/min is probably OK for most. However, unless there is a very good reason for going on, a leak this high should be investigated. For a weighted clamp (WTC) this should be below about 15 mtorr/min.
