LOW-STRESS DOPED ULTRANANOCRYSTALLINE DIAMOND

摘要

Nanocrystalline diamond coatings exhibit stress in nano/micro-electro mechanical systems (MEMS). Doped nanocrystalline diamond coatings exhibit increased stress. A carbide forming metal coating reduces the in-plane stress. In addition, without any metal coating, simply growing UNCD or NCO with thickness in the range of 3-4 micron also reduces inplane stress significantly. Such coatings can be used in MEMS applications.
