Production tools using high vacuum environments are increasingly used by industry, with their requirements growing more difficult. Two such applications are flat panel displays and magnetic hard disks. The flat panel uses up to 1.2 x 1.6 meter rectangular substrates of 1.1 mm thick glass, while hard disks are typically 95 mm circular aluminum. The methods for thin film deposition by sputtering for the two systems varies greatly for the two applications. The same thing is true for substrate transport. But some methods and principals remain the same in either type of production. Vacuum levels run from 1.0E-08 Torr for high vacuum to sputtering pressures of 5.0E-03 Torr. This article looks at two specific examples of vacuum system architecture and draws out the specifics of difference and samenesss between the two.
