Abstract:
1. A semiconductor device, comprising: a diode comprising an epitaxial layer on a semiconductor substrate, and first and second diode contacts on different planes; a passivation layer having a planar top surface, the passivation layer comprising a first sub-layer of a benzocyclobutene (BCB) material formed on the diode and a second sub-layer of BCB material formed on the first sub-layer with no intervening layer, an aggregate thickness of the passivation layer exceeding a thickness of the epitaxial layer; and a conductive layer formed on the top surface of passivation layer, the conductive layer connecting with the first and second diode contacts through first and second openings in the passivation layer, respectively, wherein the passivation layer provides a capacitive isolation between the conductive layer and the diode.
