  • Publication number: 20240178180
    Abstract: A method for manufacturing semiconductor packages. The method includes providing a first semiconductor die including a plurality of metallization layers; completely overlaying a topmost one of the metallization layers with a barrier layer; completely overlaying the barrier layer sequentially with a stop layer and a laser liftoff layer; attaching a first side of the first semiconductor die to a first wafer through at least the laser liftoff layer; attaching a second side of the first semiconductor die to a second wafer; removing the first wafer from the first semiconductor die based on the laser liftoff layer; forming a plurality of connectors on the first side of the first semiconductor die to electrically couple to the topmost metallization layer; and bonding the first semiconductor die to a third wafer that includes a second semiconductor die.

  • Patent number: 9365947
    Abstract: A mask is formed over a first conductive portion of a conductive layer to expose a second conductive portion of the conductive layer. An electrolytic process is performed to remove conductive material from a first region and a second region of the second conductive portion. The second region is aligned with the mask relative to an electric field applied by the electrolytic process. The second region separates the first region of the second conductive portion from the first conductive portion. The electrolytic process is concentrated relative to the second region such that removal occurs at a relatively higher rate in the second region than in the first region.

  • Publication number: 20150255429
    Abstract: An apparatus relates generally to a three-dimensional stacked integrated circuit. In such an apparatus, the three-dimensional stacked integrated circuit has at least a first die and a second die interconnected to one another using die-to-die interconnects. A substrate of the first die has at least one thermal via structure extending from a lower surface of the substrate toward a well of the substrate without extending to the well and without extending through the substrate. A first end of the at least one thermal via structure is at least sufficiently proximate to the well of the substrate for conduction of heat away therefrom. The substrate has at least one through substrate via structure extending from the lower surface of the substrate to an upper surface of the substrate. A second end of the at least one thermal via structure is coupled to at least one through die via structure of the second die for thermal conductivity.

  • Publication number: 20070194301
    Abstract: One aspect of the invention relates to a semiconductor arrangement having at least one nonvolatile memory cell which has a first electrode comprising at least two layers; and having an organic material, the organic material forming a compound with that layer of the first electrode which is in direct contact. One aspect of the invention furthermore relates to a method for producing the nonvolatile memory cell, a semiconductor arrangement having a plurality of memory cells according to the invention, and a method for producing the same.
