Soft passivation layer in semiconductor fabrication

Soft passivation layer in semiconductor fabrication

The use of an etch stop layer to define a terminal via opening to access a device feature after formation of a photosensitive soft-passivation layer. The etch layer allows the size of the terminal via opening to be decoupled from the resolution capabilities of current photosensitive soft-passivation...

Zusammenfassung:The use of an etch stop layer to define a terminal via opening to access a device feature after formation of a photosensitive soft-passivation layer. The etch layer allows the size of the terminal via opening to be decoupled from the resolution capabilities of current photosensitive soft-passivation layer.
