Choose bonding method
Comparing the three bonding methods in the EVG NIL
| . | Eutectic bonding | Fusion bonding | Anodic bonding |
|---|---|---|---|
| General description | For bonding two substrates by use of an interphase that makes an eutecticum. | For bonding two identical materials. | For bonding Si and Glass. |
| Bonding temperature | Depending on the eutecticum 310°C to 400°C . | Depending on defects 50°C to 400°C . | Depending on the voltage 300°C to 500°C Standard is 400°C . |
| Annnealing temperature | No annealing | 1000°C in the bond furnace C3 | No annealing |
| Materials possible to bond | Bonding of substrates is done by use of the eutectica Au/Si, Au/Sn and Au/Sn/Ni | Si/Si, SiO/SiO | Si/Pyrex (glass) |
| Substrate size | Up to 6" (aligning only possible for 4" and 6") | Up to 6" (aligning only possible for 4" and 6") | Up to 6" (aligning only possible for 4" and 6") |
| Cleaning | Cleaning by N2. | Wet chemical cleaning, IMEC. | Cleaning by N2. |
| IR alignment | Double side polished wafers. | Double side polished wafers. | Not relevant. |
