passivation

[‚pas·ə′vā·shən]
(electronics)
Growth of an oxide layer on the surface of a semiconductor to provide electrical stability by isolating the transistor surface from electrical and chemical conditions in the environment; this reduces reverse-current leakage, increases breakdown voltage, and raises power dissipation rating.
(metallurgy)
To render passive; to reduce the reactivity of a chemically active metal surface by electrochemical polarization or by immersion in a passivating solution.

passivation

Treatment of a metal surface which leaves a protective coating, rendering the surface less reactive chemically.
