Plasma Activation (EVG 810)
Jump to navigation Jump to search
This a capacitively coupled Oxygen plasma activation system used exclusively for the surface activation of clean surfaces prior to wafer bonding. This technique allows bonding temperatures to be lowered and is used as a companion tool to the Karl-Suss SB6 wafer bond tool.
- Gases used: O2 and N2
- Sample size: pieces to 6” wafer
- Max power: 200W
- Recipes characterized for substrate thicknesses between 250um and 750um. Thicknesses outside of this range need to have parameters optimized to minimize reflective power.
