Faqs:
1. What is the typical resistivity range of your high-resistivity silicon wafers?
Our wafers offer resistivity from 1,000 – 10,000 Ω·cm, customizable to meet specific research requirements.
2. Can you guarantee batch-to-batch resistivity consistency?
Yes, each batch undergoes strict four-point probe testing.
3. What is the maximum wafer size available for high-resistivity silicon?
Standard sizes range from 2 inches to 12 inches. Custom diameters up to 18 inches can be produced upon request.
4. Do you offer wafers with specific crystal orientations (e.g., , )?
Yes, we produce wafers in common orientations like <100> and <111>, and can customize rare orientations for specialized experiments.
5. What surface finishes are suitable for MEMS device fabrication?
We recommend our double-side polished wafers with Ra < 0.3 nm, ideal for precise MEMS structures and bonding processes.
6. How are wafers packaged to prevent damage during international shipping?
Each wafer is individually wrapped in anti-static film, placed in ESD trays, and secured with shock-absorbing materials in a rigid box.
7. What is the minimum order quantity for custom high-resistivity wafers?
Please contact us to obtain the minimum order quantities for different products.
8. Can you provide wafers compliant with SEMI standards?
All our wafers meet or exceed SEMI MF1500 and MF1225 specifications. Certificates of compliance are included with each shipment.
9. How quickly can you deliver custom-ordered wafers?
Standard lead time for custom wafers is 4 – 6 weeks. Urgent orders can be expedited within 2 – 3 weeks for an additional fee.
10. Can wafers be pre-cleaned for immediate use in cleanroom environments?
Yes, we offer pre-cleaning services following RCA standard protocols, reducing lab preparation time.
11. How do you ensure resistivity stability over long storage periods?
Our wafers are stored in nitrogen-filled chambers to prevent oxidation. Shelf life exceeds 12 months under recommended conditions.
12. What support do you offer for troubleshooting wafer-related issues?
Our technical team provides 24/7 support, including on-site assistance for complex research projects.
13. Are your high-resistivity wafers suitable for cryogenic applications?
Yes, our wafers maintain resistivity stability down to 4K, making them ideal for quantum computing and low-temperature electronics research.
14. Can you provide samples for evaluation before bulk ordering?
We offer sample wafers at reduced cost. Contact us with your project details to request samples.
