Investigation of Titanium target pieces for PVD sputtering

Ti target for PVD sputtering / increase coating material yield
Ti target for PVD sputtering

After using Titanium Grade 2 we faced different erosion profiles and obvious the material seems to have also different grain size
  • Preparation: US cleaning in 2-Propanol, Cross section through the sputter groove

  • Method: Scanning Electron Microscope LEO 1530 VP| Light Optical Microscope Olympus BX51, digital imaging Keyence VHX 700

The sputter profile after end of use had big visible differences
