Abstract
In one embodiment, a method manufactures a semiconductor device including metallizations having peripheral portions with one or more underlying layers having marginal regions extending facing the peripheral portions. The method includes: providing a sacrificial layer to cover the marginal regions of the underlying layer, providing the metallizations while the marginal regions of the underlying layer are covered by the sacrificial layer, and removing the sacrificial layer so that the marginal regions of the underlying layer extend facing the peripheral portions in the absence of contact interface therebetween, thereby avoiding thermo-mechanical stresses.
