PRINTHEAD DIE WITH MULTIPLE TERMINATION RINGS |
摘要 |
A printhead die includes a SiO2 layer grown into a surface of a silicon substrate, and a dielectric layer deposited onto an interior surface area of a substrate. Multiple termination rings are formed around the interior surface area. Each ring is defined by an absence of the dielectric layer. A berm is located in between each termination ring. Each berm is defined by the presence of the dielectric layer. |
