Abstract:
A semiconductor device includes a contact metallization layer that includes aluminum and is arranged on a semiconductor substrate, an inorganic passivation structure arranged on the semiconductor substrate, an organic passivation layer comprising a first part that is arranged on the contact metallization layer, and a second part that is arranged on the inorganic passivation structure, a first layer structure including a first part that is in contact with the contact metallization layer, a second part that is contact with the inorganic passivation structure, and a third part that is disposed on the semiconductor substrate laterally between the inorganic passivation structure and the organic passivation layer.
