In constructing many of today’s MEMS devices, it is necessary to modify the surface of the substrate to improve adhesion of additional coatings or to prevent substances from attaching to the substrate.

Brewer Science offers coatings that change the surface energy of the substrate to enhance the desired surface properties. The coatings can provide high, medium, or low surface energies to attract or repel other chemistries. APX-K1 material is a spin-on coating that produces films nanometers thick, offers high surface energy, and attracts similar high-surface-energy coatings.

Brewer Science^® Theta™ coatings offer low surface energy to repel water, inks, and other materials. These coatings come in versions that produce films with a range of thicknesses, from monolayers that are a few nanometers thick to films that are microns in thickness.

Materials:

• APX-K1 coating
• Theta™ M10 coatings
