Abstract
A semiconductor device with electrical overstress (EOS) protection is disclosed. The semiconductor device includes a semi-insulating layer, a first contact disposed onto the semi-insulating layer, and a second contact disposed onto the semi-insulating layer. A passivation layer is disposed onto the semi-insulating layer. The passivation layer has a dielectric strength that is greater than that of the semi-insulating layer to ensure that a voltage breakdown occurs within the semi-insulating layer within a semi-insulating region between the first contact and the second contact before a voltage breakdown can occur in the passivation layer.
