BLNKK's current understanding
Please check the details- Wafer / device
- Ultrathin silicon wafer or die; final thickness, diameter, and front-side structure unconfirmed
- Observation
- Backside chipping, radial cracks, handling fracture, or post-debond damage
- Process stage
- Temporary bonding, coarse / fine grinding, stress relief, dicing, handling, and debonding
- Variables to validate
- Thickness, grinding-damage layer, wafer edge, dicing order, carrier, and debond method
- Missing information
- Staged defect maps, thickness / TTV, backside condition, carrier, and debond traces
Paths to assess first
Paths serve different purposes and can be combined01
Staged defects and location correlationIdentify the earliest visible damage stage
First02
Grinding-damage layer and dicing flowCompare stress relief, edge treatment, and DBG
First03
Temporary support and debond windowEvaluate carrier support, peel forces, and residues
