About

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.

No etching nor photoresist is allowed in this tool!  
It is for "clean" bonding activation only, not plasma etching.

Detailed Specifications

• Gases used: O₂ and N₂
• Sample size: pieces to 6” wafer
• Recipes characterized for substrate thicknesses between 250um and 750um. Thicknesses outside of this range need to have parameters optimized to minimize reflective power.
