The adhesion of sputtered Copper (Cu) coatings on plane glassy Carbon (C) substrates can be increased by a Nitrogen-RF-plasma pre-treatment and by use of thin Molybdenum (Mo) interlayers. If the Cu coating is deposited directly on a plasma treated C substrate at room temperature the adhesion of Cu to C is excellent. A following thermal treatment (800 °C, high vacuum, 1 h) reduces the adhesion of Cu to C due to de-wetting of the Cu coating from the C substrate by grain boundary grooving. De-wetting can be suppressed if a 100 nm Molybdenum interlayer is present and the adhesion values are also increased again. This work shall analyse the interface in the C/Cu and C/Mo/Cu sample by analytical Cross Sectional Transmission Electron Microscopy and Secondary Ion Mass Spectroscopy.
