  • Publication number: 20170033078
    Abstract: A multi-device package includes a substrate, at least two device regions, a first redistribution layer, an external chip, a plurality of first connectors and a conductive contact. The two device regions are formed from the substrate, and the substrate has a first surface and a second surface opposite to the first surface. The first redistribution layer is disposed on the first surface and electrically connected to the two device regions, and the external chip is disposed on the first redistribution layer. The first connectors are interposed between the first redistribution layer and the external chip to interconnect the first redistribution layer and the external chip, and the conductive contact is extended from the second surface to the first surface of the substrate to electrically connect the device region.

  • Publication number: 20100240214
    Abstract: A method of forming the multi metal layers thin film has Ti sputtered on top surface of a substrate by PVD first. Then, Ti is transformed into TiN via CVD. Thus, by skipping the extra process steps of wafer cleaning and surface treating, the method not only solves the stress problems between two different metal layers but also improves the cycle time and particle performance for the production without any yield impact.
