Connection line structure and forming method thereof

Abstract

Disclosed are a connection line structure and a forming method thereof. The connection line structure includes a passivation layer, a metal layer, and a protective layer, the metal layer is arranged on the passivation layer, and the protective layer is arranged on the metal layer. In the present application, a simple single-layer wiring design may be utilized, and a multi-layer three-dimensional wiring design may also be utilized to implement high speed transmission, a MEMS process allows for design of a connection line in a straight or bent layout, a connection line of a bent layout is flexible, and better compatibility is achieved.

Dependencies are inferred from the claim text.
