Modifying surfaces

One of the major modifications of surface properties by plasma technology is the ⇒ modification of the surface tension.The effects of surface treatment by etching are a very important factor:

  • Chemical plasma etching or micro-sandblasting increases the surface and thus further improves the adhesive properties
  • By anisotropic etching (⇒ ion etching, ⇒RIE), surface structures for the semiconductor electronics are generated.

By means of plasma coating, surface coats can be equipped with modified properties:

  • for instance protective coats on electronic circuits
  • scratch-proof DLC coats, also CD
  • wear-proof gearbox components
  • water-repellent PTFE or HMDSO coats
