Choose bonding method

  • Eutectic bonding
  • Fusion bonding
  • Anodic bonding

Comparing the three bonding methods

. Eutectic bonding Fusion bonding Anodic bonding
General description For bonding an interphase that makes an eutecticum eg. Au/Si (two different matarials). For bonding two identical materials eg. Si/Si. For bonding Si and Glass.
Bonding temperature Depending on the eutecticum 310 oC to 400 oC. Depending on defects 50 oC to 400 oC. Depending on the voltage 300 oC to 500 oC Standard is 400 oC.
Annnealing temperature No annealing 1000 oC in the bond furnace C3 No annealing
Max. scan range z <100Å to~0.3mm 50Å to 262µm 1 µm (can go up to 5 µm under special settings)
Resolution xy up to 5900 data points per profile down to 0.067 µm Depending on scan size and number of samples per line and number of lines - accuracy better than 2%
Resolution z 1Å or 25Å 1Å, 10Å or 20Å <1Å - accuracy better than 2%
Max. scan depth [µm] (as a function of trench width W) 0.87(W[µm]-5µm) 1.2(W[µm]-5µm) ~1 with standard cantilever.
Tip radius 5 µm 60o cone 5 µm 45o cone <12 nm on standard cantilever
Stress measurement Can be done Can be done Cannot be done
Surface roughness Can be done on a line scan Can be done on a line scan Can be done on a selected surface area
