What it is
The Ulvac EX 550 C 12 is a vapor-deposition system used in semiconductor manufacturing.[1]
How it works
General reference — not yet source-verifiedVapor-deposition systems deposit thin films of material onto a substrate by introducing precursor gases into a vacuum chamber, where chemical reactions or physical condensation form the film.
Where it fits in the process flow
General reference — not yet source-verifiedVapor-deposition systems are used after wafer cleaning and before photolithography in the semiconductor fabrication sequence.
The deposited films serve as dielectrics, conductors, or barriers for subsequent etching and patterning steps.
Applications
General reference — not yet source-verifiedThe system can be employed in the production of compound-semiconductor devices and microelectromechanical systems.
