BLNKK's current understanding
Please check the details- Object and structure
- Upstream SiC ingots and as-sliced wafers
- Stage of occurrence
- Multi-wire ingot slicing and inspection before grinding/polishing
- Observable symptoms
- As-sliced thickness variation, TTV, slicing cracks and subsurface damage
- Engineering decision
- Use thickness maps and damage evidence to compare wire-slicing windows and downstream removal allowance
Paths to assess first
Paths serve different purposes and can be combined01
As-sliced geometry and damage evidencePair thickness/TTV maps with crack and damage-layer measurements to separate geometry variation from machining damage.
First02
Wire-slicing and fluid-delivery controlsHold sampling references constant and compare wire, tension, feed, rocking and fluid-delivery windows one factor at a time.
First03
Downstream grinding/polishing allowancePair damage depth with target thickness to check whether downstream grinding/polishing has enough removal allowance.
