Printhead Die With Damage Detection Conductor Between Multiple Termination Rings |
| 摘要 |
In one example implementation, a printhead die includes a SiO2 layer grown into a surface of a silicon substrate, a dielectric layer formed on the surface over an interior area of the substrate, a first termination ring surrounding the interior area and defined by an absence of the dielectric layer, a berm surrounding the first termination ring and defined by the presence of the dielectric layer, a damage detection conductor formed under the berm on the SiO2 layer, and a second termination ring surrounding the berm and defined by an absence of the dielectric layer. |

1. A printhead die comprising:
a SiO2 layer grown into a surface of a silicon substrate; a dielectric layer formed on the surface over an interior area of the substrate; a first termination ring surrounding the interior area and defined by an absence of the dielectric layer; a berm surrounding the first termination ring and defined by the presence of the dielectric layer; a damage detection conductor formed under the berm on the SiO2 layer; and, a second termination ring surrounding the berm and defined by an absence of the dielectric layer. |
