Publication number: 20220344303Abstract: A method for manufacturing electronic chips includes depositing, on a side of an upper face of a semiconductor substrate, in and on which a plurality of integrated circuits has been formed, a protective resin. The method includes forming, in the protective resin, at least one cavity per integrated circuit, in contact with an upper face of the integrated circuit. Metal connection pillars are formed by filling the cavities with metal. The integrated circuits are separated into individual chips by cutting the protective resin along cut lines extending between the metal connection pillars.Type: ApplicationFiled: July 8, 2022Publication date: October 27, 2022Applicant: STMICROELECTRONICS (TOURS) SASInventors: Ludovic FALLOURD, Christophe SERRE

Patent number: 11393785Abstract: A method for manufacturing electronic chips includes forming, on a side of an upper face of a semiconductor substrate, in and on which a plurality of integrated circuits has been formed, trenches laterally separating the integrated circuits. At least one metal connection pillar per integrated circuit is deposited on the side of the upper face of the substrate, and a protective resin extends in the trenches and on an upper face of the integrated circuits. The method further includes forming, from an upper face of the protective resin, openings located across from the trenches and extending over a width greater than or equal to that of the trenches, so as to clear a flank of at least one metal pillar of each integrated circuit. The integrated circuits are separated into individual chips by cutting.Type: GrantFiled: December 2, 2020Date of Patent: July 19, 2022Assignee: STMicroelectronics (Tours) SASInventors: Ludovic Fallourd, Christophe Serre
