Silicon substrates
Review removal stage, starting surface, plate or pad, carrier chemistry and required cleanliness before selecting a micron range.
Precision substrate processing
Diamond Powder for Semiconductor Wafer Lapping & Polishing
Choose the powder around the substrate and process stage—not around a generic “semiconductor grade” label. Particle structure, size distribution, carrier, plate or pad and cleanliness target all affect removal rate, scratches and downstream yield.
Typical process stages
01Stock-removal lapping
02Fine lapping
03Precision polishing
04Surface verification
Where the discussion starts
Define the substrate and the surface target first
Each route requires process trials. The cards describe selection conversations, not a universal grade recommendation.
SiC and hard substrates
Hard-brittle materials can require a different balance of cutting strength, particle shape and scratch control. Sample qualification is essential.
Sapphire substrates
Fine and regularly shaped powders may be evaluated where surface finish and random deep-scratch control are important.
Advanced material trials
GaN-related, ceramic and other substrate workflows are reviewed from the actual process; suitability is not assumed from material name alone.
Process evidence
What changes powder behavior
- Substrate material, hardness and starting condition
- Stock removal, fine lapping or final polishing stage
- Plate or pad material, pressure, speed and slurry delivery
- Allowed scratch level, edge condition and target roughness
Specification review
What we confirm before quoting
- Diamond structure and grade family
- Nominal particle range and distribution requirement
- Powder, paste, suspension or customer formulation route
- Sample quantity, inspection requirement and repeat-volume plan

Supply boundary
Diamond micron powder for process trials
The standard quotation starts from a confirmed powder grade and particle range. Paste, suspension or customer-specific carrier systems are not assumed; their availability and formulation scope must be confirmed separately in the quotation.
- Micron powder grade and particle range confirmed before sampling
- Representative morphology and particle-distribution information by proposed grade
- Batch reference, packing, TDS or SDS supplied when available and agreed
- Wafer finish, removal rate and yield remain customer-process validation results
Real supply image
Powder supplied by grade and particle range
The exact grade, particle range, batch reference and packaging are confirmed on the quotation and sample.
- Sample-to-production discussion
- Grade and size confirmation
- Repeat-order reference control
Particle evidence
Morphology matters alongside nominal size
A size name alone does not describe cutting points, shape or distribution. Ask for the evidence relevant to the proposed grade.
- Representative morphology review
- Distribution requirement discussion
- Batch-specific documents by agreement
Qualification note
No powder is presented as universally suitable for silicon, SiC, GaN or sapphire. Final suitability depends on the customer’s process and should be approved by sample testing.
For a focused recommendation
Send the actual wafer process
A current powder specification, slurry information or surface report helps narrow the first trial.

Wafer-process inquiry
Request a micron-powder sample review
Send the substrate, process stage, plate or pad, current consumable, surface target and trial quantity. We will confirm the powder route and available documentation.
Sample qualification
Start with one defined process stage
Send the substrate, current consumable and target result. We will narrow the powder family before discussing volume supply.
