Diamond MEMS 101

FAQs & How To’s

How to store the substrates?

Store in a dry vial at 25°C. Prefereably in an inert atmosphere.


How to clean the substrates?

Acid wash, electrochemical cleaning using 0.1 M sulphuric acid.


Can UNCD be polished?

Yes. It can be polished with alumina slurries similar to glassy carbon and sonicated in water.


Can UNCD be micro or nano-patterned?

Yes. A reactive ion etching (SF6/O2) recipe is provided in this “Diamond MEMS 101” guide which provides a Diamond Etch Recipe (see brochure at left)
