SCRATCHPROOF COATING FOR SEMICONDUCTOR COMPONENTS |
| 摘要 |
The aim of the invention is to increase the scratchproofness of a surface passivation, especially for fingerprint sensors. To this end, a sliding layer made of fat, oil, surfactants and/or wax is applied. Said layer reduces shearing forces. In a preferred embodiment, an emulsion made of water, paraffin oil, propyl glycol, lactarimic acid, cetylic acid, TEA, beeswax, carbomer 954, methylparaben, propylparaben and optionally perfume is used.
