WebWe report on studies focused on the electron-beam (E-Beam) evaporation of gold (Au) that have enabled us to develop a fundamental understanding of the causes of spitting. We have found that the factors that affect spitting can be divided into two broad groups: 1) evaporation process parameters and 2) material quality. WebJan 5, 2024 · Overall, the main difference between e-beam evaporation and thermal evaporation is the method used to vaporize the material. E-beam evaporation uses a beam of high-energy electrons, while thermal evaporation uses heat.
