FAQs of COATED SILICON WAFER GOLD/SILVER/PLATINUM/CHROMIUM:


Q: How do I select the optimum coating thickness and metal for my application?

A: Choosing the right coating thickness and metal depends on your application requirements. For high conductivity or reflectivity, gold or silver is preferred, while platinum and chromium are selected for enhanced durability and chemical resistance. Thickness typically ranges from 20 nm500 nm; our experts can help you personalise your selection.

Q: What cleaning and storage process ensures wafer surface quality?

A: Wafers are subjected to ultra-clean class 100 procedures and must be stored in a cleanroom environment (1822C, dry nitrogen recommended) to maintain <0.5 ppm surface contamination, preserving their integrity for high-precision applications.

Q: Where are these coated silicon wafers commonly used?

A: Coated silicon wafers are widely used in semiconductor device fabrication, MEMS production, microfabrication, thin-film research, sensors, and optical applications, serving both research and industrial needs.

Q: What benefit does the mirror-polished finish provide for users?

A: The mirror-polished finish, achieved with RMS roughness <1 nm, offers unrivaled smoothness, improving device performance, thin-film uniformity, and optical clarity, crucial for high-precision research and advanced electronic applications.

Q: Can the wafer be customised for specific dimensions or coatings?

A: Absolutely. We provide extensive options for diameter (26 inches, custom on request), thickness, coating type, and crystal orientation, allowing users to personalise wafers to best suit their project needs.

Q: What is the process of obtaining customised coated wafers?

A: Begin by discussing your technical requirementsdimensions, coating preference, thickness, and adhesion layerwith our technical team. After evaluation, production is tailored to your specifications, ensuring optimum quality and reliable delivery.
