Patent ID: 7781331

Claim:
Method for producing an electronic component comprising at least one electrically conductive bushing through a semiconductive or non-conductive substrate thereof, which is particularly suitable for electric applications, wherein a front side of the substrate is provided with one or more layers as well as with at least one electrically conducting contact structure within or on said layers, comprising: (a) providing said semiconductive or non-conductive substrate; (b) forming at least one recess in the substrate, starting from the said front side that extends through said layers, beside at least one conducting contact structure; (c) applying an electrically conductive structure which extends, at least starting from said conductive contact structure, down to the base of the recess, such that it forms an electrically conductive contact point; (d) forming at least one recess in the substrate from its rear side, such that said recess ends below that location or below one of the locations where the electrically conductive contact point or one of the said electrically conductive contact points is situated on the front side of the substrate, and is completely covered by the latter; and (e) applying from the rear side of the substrate an electrically conductive structure, which establishes a conductive connection between said respective contact point and said rear-side surface of the substrate through said recess or at least one of the recesses, wherein the conductive connection will serve as a conductive bushing of the finalized electronic component.
