AJA ATC ORION Series Evaporation System

Evaporation Systems can be configured for high rate, low rate, multi-layer and co-deposition applications depending on the chamber, sources, substrate carrier and general configuration chosen. Proper power, crucible liner or boat material, soak, and XY sweep decisions must be made for each material to be evaporated to ensure the desired rates, stability and film characteristics. Typically materials with good heat transfer properties (eg. Al) do not require XY sweep but may require a liner (Au) wheras materials with poor thermal properties (Cr) tend to tunnel and spit unless the e-beam power is diffused with an XY sweep. Proper substrate fixturing is required to obtain the best uniformity.
