发明名称 Method for fabricating semiconductor components using maskless back side alignment to conductive vias
摘要 A method for fabricating semiconductor components includes the steps of: providing a semiconductor substrate having a circuit side, a back side and conductive vias; removing portions of the substrate from the back side to expose terminal portions of the conductive vias; depositing a polymer layer on the back side encapsulating the terminal portions; and then planarizing the polymer layer and ends of the terminal portions to form self aligned conductors embedded in the polymer layer. Additional back side elements, such as terminal contacts and back side redistribution conductors, can also be formed in electrical contact with the conductive vias. A semiconductor component includes the semiconductor substrate, the conductive vias, and the back side conductors embedded in the polymer layer. A stacked semiconductor component includes a plurality of components having aligned conductive vias in electrical communication with one another.
