Abstract
A semiconductor device includes a diode, a passivation layer and a conductive layer. The diode includes an epitaxial layer on a semiconductor substrate, and first and second diode contacts on different planes. The passivation layer has a planar top surface, and includes multiple consecutive layers of a benzocyclobutene (BCB) material formed on the diode, an aggregate thickness of the passivation layer exceeding a thickness of the epitaxial layer. The conductive layer is formed on the top surface of passivation layer, the conductive layer connecting with the first and the second diodes contact through first and second openings in the passivation layer, respectively. The passivation layer enhances a capacitive isolation between the conductive layer and the diode.
