Electrostatic-erasing abrasion-proof coating and method for forming the same |
| 摘要 |
An abrasion-proof and static-erasing coating is formed on the contact surface of a contact image sensor. The coating comprises a first film having a high hardness and a low conductivity, a second film formed on the first film and having a low hardness and a high conductivity, and a third film having a high hardness and a high resistivity providing an abrasion-proof insulating external surface.
