摘要：
Embodiments of the invention provide a semiconductor chip having a passivation layer extending along a surface of a semiconductor substrate to an edge of the semiconductor substrate, and methods for their formation. One aspect of the invention provides a semiconductor chip comprising: a semiconductor substrate; a passivation layer including a photosensitive polyimide disposed along a surface of the semiconductor substrate and extending to at least one edge of the semiconductor substrate; and a channel extending through the passivation layer to the surface of the semiconductor substrate.
