What it is

The Denton Vacuum SJ20C is an e-beam evaporation system used for physical vapor deposition. The system includes a four-source hearth and a film thickness monitor. Evaporation materials available include aluminum, silver, gold, gold-germanium, chromium, copper, germanium, molybdenum, nickel-chromium, niobium, nickel, tantalum, titanium, and tungsten.[1]

Where it fits in the process flow

General reference — not yet source-verified

E-beam evaporation systems are used in semiconductor fabrication for depositing thin films of metals and dielectrics. The process typically follows photolithography and etching steps, where the deposited film forms conductive or insulating layers. The substrate is loaded into the vacuum chamber, and after deposition, the wafer may undergo lift-off or further processing.

Applications

The Denton SJ20C is used for depositing a wide range of materials, including high-temperature metals and ceramics. Applications include optical coatings, semiconductor manufacturing, and temperature-resistant coatings. The system can deposit aluminum, silver, gold, gold-germanium, chromium, copper, germanium, molybdenum, nickel-chromium, niobium, nickel, tantalum, titanium, and tungsten.[1]
