Abstract
A semiconductor chip includes flip chip contacts that are arranged on contact surfaces of an active top side of the semiconductor chip. The contact surfaces are surrounded by a passivation layer that covers the active top side while leaving exposed the contact surfaces. The passivation layer includes thickened portions that surround the contact surfaces. The semiconductor chip formed with thickened portions around the contact surfaces is protected from delamination during packaging of the semiconductor chip to form a semiconductor device.
