Semiconductor graphite parts carry a double demand: purity and precision. A trace contaminant or a loose tolerance ruins the process. This article covers five specs that let graphite products meet cleanroom duty.
Jiecheng Graphite (since 2003) machines semiconductor graphite products to spec, and confirms purity in writing.
Five specs that meet cleanroom duty
Purity sets the contamination limit. Grade matches temperature and chemical load. Precision holds the tolerance for the process. Surface finish controls particles. And packaging keeps the part clean to your line.
· Purity — meets the contamination limit
· Grade — temperature and chemical load
· Precision — held process tolerance
· Finish — controls particles
· Packaging — clean to your line
Where semiconductor parts are used
Semiconductor graphite appears in CVD, etch and other hot processes where purity and precision matter. Confirm the process, temperature and purity before ordering.
· CVD and epitaxy components
· Etch and deposition fixtures
· Susceptors and hot-zone parts
What to specify before you buy
Send the process, purity, temperature and tolerance. Jiecheng Graphite machines these parts in its 3,000 m² Dalang plant and ships worldwide.
Spec | What to confirm | Why it matters |
Purity | Limit value | Controls contamination |
Grade | Temp + chemical | Sets resistance |
Precision | Tolerance | Fits process |
Finish | Ra value | Controls particles |
Packaging | Clean handling | Protects part |
Buying checklist
1. Send process, purity and temperature
2. Specify grade and tolerance
3. Confirm finish and packaging
4. Agree inspection per batch
5. Freeze the part spec
FAQ
Why does purity matter in semiconductors?
Trace contamination ruins the process, so the limit must be confirmed.
Can graphite handle etch processes?
Yes, with a grade matched to the chemistry and temperature.
How is the part kept clean?
By finish, packaging and clean handling to your line.
Protecting a cleanroom process
A cleanroom part is only as clean as its whole chain, from grade to packaging. Confirm purity, finish and handling before ordering, and keep the batch data. Jiecheng Graphite documents purity on every semiconductor part and controls packaging, so the part is clean to your line.
· Confirm purity and finish limits
· Verify packaging and handling
· Document batch data per part
Semiconductor duty needs purity, grade, precision, finish and packaging, all confirmed. Jiecheng Graphite has supplied cleanroom parts since 2003 and keeps the spec on file.
