- We found out that single laser pulses with both nano- and femto-second laser sources did not harm the surface passivation on SiO2 + a-Si:H hardmask samples.
- electrode passivation
- damage to the passivation
- passivation quality
Examples
-
The passivation of the metal surface helps prevent corrosion and extends the lifespan of the material.
-
The advantages of the solution oxidation process are simplicity, low cost, and rapid passivation of the Co(P).
Academic text (1998) -
The microscopic analysis was then followed by a study of the impact of patterning on the passivation quality on a macroscopic scale.
Academic text (2018) -
This allowed us to study the effect of laser damage on the passivation quality with increasing fluence values and decreasing spot-to-spot distance.
Academic text (2018) -
In silicon heterojunction solar cells, passivation is achieved by means of a few nanometers-thin hydrogenated amorphous silicon (a-Si:H) film.
Academic text (2018) -
This amorphous silicon signal is similar to the reference spectra of the SiO2 sample without the top a-Si:H mask, and it could be attributed to a-Si:H (i+n) passivation and the base contact layer below the SiO2 layer.
Academic text (2018) -
The passivation treatment made the alloy less reactive and more resistant to environmental damage.
-
In semiconductor manufacturing, passivation creates a protective layer that enhances device performance.

Etymology
The word passivation comes from passive, which originally meant 'to be acted on' or 'not active'. So in materials, passivation is the process of making a metal surface 'not active' by forming a thin protective layer that helps stop rust and corrosion.
