摘要:
A semiconductor device includes an assembly of two integrated circuits. The assembly has a layer of photoresist filling the space between the two integrated circuits, and at least one electrically conducting pillar within the resist and electrically coupling the two integrated circuits.
摘要:
A method for determining, in a first semiconductor material wafer having at least one through via, mechanical stress induced by the at least one through via, this method including the steps of: manufacturing a test structure from a second wafer of the same nature as the first wafer, in which the at least one through via is formed by a substantially identical method, a rear surface layer being further arranged on this second wafer so that the via emerges on the layer; measuring the mechanical stress in the rear surface layer; and deducing therefrom the mechanical stress induced in the first semiconductor material wafer.
