Since the early 1960s, the use of high-pressure, specialty gases in semicon
ductor manufacturing has significantly contributed to the rapid evolution o
f integrated circuit technology. Compressed gas cylinders typically contain
pressures up to 2500 psig. The potential energy controlled by these cylind
ers is a function of fill pressure and gas reactivity. This combination has
led to specialty gas cylinders often being referred to as "a sleeping gian
t."
