LightSpeed unpatterned carrier-defect comparison

Unity Semiconductor · Engineering measurement and characterization

Purpose: Carrier cleaning needs before/after or reference-sample comparisons of exposed surface defects.
Technical approach: LightSpeed uses darkfield optical inspection for defects on unpatterned surfaces.
Scope of use: Consider it for unpatterned glass carriers or silicon, with actual surface condition and detection criteria confirmed.
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
Optical signals do not identify residue chemistry or inspect buried interfaces. Patterned areas and release criteria need separate validation.
What to prepare
BLNKK suggests preparing carrier materials, surface/cleaning histories and paired samples, with the defects and criteria of interest.
Confirm with the supplier
Confirm sample-specific detection types, thresholds and repeatability, and complementary chemical or local analysis for suspected residues.
Public evidence: The current EMD/Merck offering identifies a UNITY-SC unpatterned darkfield tool and lists glass-carrier and silicon applications.
