A final passivation layer is added to the top of the wafer to seal it from water and other contaminants. |
This effect is related to the oxide layer used for passivation of the silicon surface. |
In electroplating, yellow chromatising of aluminium was replaced by chromide Al1650 for thick layer passivation of aluminium. |
A drain electrode layer is formed by a first passivation film with the first passivation film formed as an upper layer. |
When controlling a passivation bath in accordance with DIN 51360, you achieve clarity of whether the passivation is optimal. |
Finishing is carried out by means of chemical pickling with nitric acid and chromic passivation. |
