Coronus wafer-bevel residue and protection

Lam Research · Packaging processes and engineering validation

Purpose: Bonding abnormalities with evidence of edge contamination need comparisons of residues and bevel protection.
Technical approach: The Coronus family confines plasma bevel etch or deposits protective films in selected configurations.
Scope of use: Use it for wafer-bevel processing and bonding-edge integration after confirming stacks, edge profiles and model.
Limitations and open questions: These evaluation considerations are compiled by BLNKK from public information. They are not supplier guarantees or a mandatory submission checklist.
Scope and limitations
Bevel treatment does not clean the entire bond face. Family features are configuration-dependent and do not identify unexplained void causes.
What to prepare
BLNKK recommends preparing edge stacks, particle/void locations, surrounding processes and carrier information for contamination-path and sample comparisons.
Confirm with the supplier
Confirm model, material compatibility, processing extent, active-area protection, edge profiles and trial validation.
Public evidence: The manufacturer lists bevel etch/deposition, 3D-bonding edge support and wafer-bonding gap fill.
