Mark 40 E-Beam
Provisional entry — research in progress
This page was generated automatically from cited public sources and hasn't completed the full research pass yet. Every specification shown carries its source; more detail is added as research completes.
What it is
The CHA Mark 40 is an electron-beam evaporator used for physical vapor deposition in semiconductor and thin-film processing.[1][2]
How it works
The CHA Mark 40 is equipped with a four-pocket electron-beam gun that can hold up to four different metal materials, enabling sequential deposition without breaking vacuum.[2]
The system includes a CHA SR10 electron-beam power supply, an Autotech II valve controller, and a CTI 8 cryopump with a CTI compressor, which maintain the high-vacuum environment required for clean deposition.[2]
Applications
General reference — not yet source-verifiedE-beam evaporators are used for depositing metal layers, contacts, and interconnects in semiconductor devices, as well as for optical coatings, magnetic thin films, and other thin-film applications.
