The present disclosure is directed to the preparation of a semiconductor substrate, and metallization of a contact area on the substrate to produce a contact in a semiconductor device. The method includes pre-treating the substrate by ultra fast laser treatment of a contact area, and depositing an interconnect metal layer on the contact area to create a contact. The process may include depositing a layer of dielectric-forming material on the substrate and removing a portion of the dielectric material from the substrate to reveal a contact area, prior to laser treating and metallization.

摘要:
A conductive bond for through-wafer interconnect is produced by forming an electrode through a first wafer from a component on a front side of the first wafer to a back side of the first wafer, forming a first electrically conductive interface in contact with an exposed portion of the electrode on the back side of the first wafer, and conductively bonding the first electrically conductive interface with a second electrically conductive interface on a second wafer under pressure at a temperature below the thermal budget of the stacked wafer device. The process temperature is generally well below the melting points of the electrically conductive interfaces. In some embodiments, the conductive bonding may be facilitated or enabled by performing the conductive bonding in a vacuum.
