Abstract:
A high-voltage capacitor structure comprises a capacitor. The capacitor includes a substrate, a field oxidation layer, an active region, a dielectric layer, a passivation layer and a metal layer. The field oxidation layer is disposed above the substrate. The active region is disposed above the substrate or in the substrate. The dielectric layer is disposed above the active region and the field oxidation layer. The passivation layer is disposed above the dielectric layer. The metal layer is disposed above the passivation layer. The metal layer and the active region serve as a first electrode and a second electrode of the capacitor, respectively, wherein the active region is disposed below the dielectric layer. Some embodiments provide a digital isolation apparatus comprising at least one high-voltage isolator, each of which includes the above high-voltage capacitor structure.

Claim (Index 9):
