Priority items to confirm · 5
01The debonded surface and material locations are definedUnconfirmed
Is the anomaly on the post-debond surface, with temporary-bond material, release-layer, and location records available?
New mechanical cracks do not identify residual films; cleaning issues and mechanical damage can coexist. Do not infer residue composition directly from a material's trade name.
Update engineering conditions →02Locations, composition, and original controls are comparableUnconfirmed
Are residue thickness, coverage, and composition supported by uncleaned, normal, and before-and-after-cleaning controls?
Detection limits and sampling locations are required; a transparent appearance does not prove that films are absent, and XPS or EDX does not guarantee precise identification of unknown polymers.
Update engineering conditions →03Material, thermal, and debonding histories are comparableUnconfirmed
Are material cure, cumulative thermal history, debonding mechanism, and wait times traceable?
Thermoplastic and curable materials, and laser and mechanical debonding, cannot share one cleaning assumption; no universal solvent is provided across materials.
Update engineering conditions →04Support and material-compatibility controls are definedUnconfirmed
Do cleaning comparisons retain thin-wafer support and check candidate chemicals for compatibility with exposed Cu, dielectrics, and the frame?
First compare controlled small samples of the same material; less residue does not establish that metals, dielectrics, tapes, and thin wafers are undamaged.
Update engineering conditions →05Next-process specifications and before-and-after responses are comparableUnconfirmed
Are comparable records available for the next process's surface specifications and morphology, chemistry, and electrical behavior before and after cleaning?
Subsequent hybrid bonding requires a separate check of the prebond window; reducing residual films does not by itself authorize release to every downstream process.
Update engineering conditions →Relevant assessment paths

First add thermal and debonding histories, support, and chemical compatibility.
Review post-cleaning surface evidence for the next process
First add next-process specifications and before-and-after responses under support.

AFM checks local Cu recess and roughness; AFP observes larger-area topography. Local measurements and long-scale nonuniformity must be assessed separately.
Application information from 2025; its roughness and recess values must not be applied here. A small AFM field of view cannot represent particle coverage across the wafer or directly authorize bonding release.
- JEOL · JPS-9030 XPS surface-chemistry analysis ↗
View source notes and limits
The official page shows elemental, chemical-state and depth examples. GCIB/monochromatic sources are options, not demonstrated identification of this adhesive.
Scope and limitations Area averages can mix surfaces and do not guarantee micro-residue localization or unique adhesive identification. Charging, exposure and sputtering conditions can affect interpretation. What to prepare BLNKK suggests preparing material identities, before/after and blank references, residue area/location and handling history for matched-condition spectra. Confirm with the supplier Confirm analysis area, sample compatibility, charge compensation and settings. For depth work, review ion/GCIB options, potential sample alteration and reference-spectrum interpretation.

Merck explicitly lists cured-silicone removal in temporary bonding.
Scope and limitations Do not extend the claim to arbitrary polymers or all metal/dielectric surfaces. Clean appearance alone does not establish suitability for the next bonding step. What to prepare BLNKK suggests preparing adhesive/cure history, residue thickness/exposed area, surface materials and downstream requirements for coupon comparisons of removal, material changes and residue. Confirm with the supplier Request current TDS/SDS, supported adhesives and process guidance. Confirm soak/rinse/dry conditions, stack compatibility, downstream surface validation and availability.

Scope and limitations Substrate signals, mixtures or aging can prevent unique identification; ATR contact can affect samples. FT-IR, FPA and IR-laser branches have different spectral/mode coverage. Spectra alone do not establish cleanliness acceptance. What to prepare BLNKK suggests documenting residue size/location and substrate, with clean controls and known adhesive/cured references. State preservation needs. Confirm with the supplier Confirm configuration, spectral coverage, measurement mode, reference libraries and ATR contact conditions, plus any quantitative calibration or complementary analysis.
- Thermo Fisher Scientific · Nicolet iN10 MX infrared analysis of debond residues ↗

Scope and limitations Dimensions, residue thickness and substrate background affect identification. Small residues may escape detection; ATR contact and chemical identity do not establish cleaning compatibility or release. What to prepare BLNKK suggests preparing adhesive/cleaner references, debond/cleaning histories, residue locations and uncleaned/cleaned specimens. Confirm with the supplier Confirm sampling, detector/imaging options, background handling, resolvable residue dimensions and ATR contact effects; agree on reference spectra and comparison methods.

EAG's service page and three-page note revised in 2022 describe capabilities, matrix effects and quantitation limits.
Scope and limitations Matrix effects prevent direct conversion of intensity to concentration. Low-dose static analysis differs from sputter profiling; neither establishes cleaning compatibility.

- For silicone-based temporary bonding; confirm the actual adhesive, cure state, residue geometry and substrate stack.
- Polymers, films and organic contamination with interpretable spectra; mode, detector and sample access must match.
- Exposed residues must be resolvable by the selected sampling mode; confirm detector, imaging and ATR configuration for actual specimens.
- Documented for organic/inorganic and conducting/insulating surfaces; confirm vacuum compatibility and sample condition.
- Consider it for unpatterned glass carriers or silicon, with actual surface condition and detection criteria confirmed.
