  • Patent number: 10553453
    Abstract: Various embodiments of the disclosure are directed to a semiconductor package and a method for fabrication of the semiconductor package. Further, disclosed herein are systems and methods that are directed to using a photoimagable dielectric (PID) layer with substantially similar mechanical properties as that of a mold material. The disclosure can be used, for example, in the context of bumpless laserless embedded substrate structures (BLESS) technology for wafer/panel level redistribution layer (RDL) and/or fan-out packaging applications. The disclosed embodiments may reduce the need for multiple dry resist film (DFR) lamination steps during various processing steps for semiconductor packaging and can also facilitate multiple layer counts due to the availability of thin PID materials.

  • Publication number: 20190393109
    Abstract: Semiconductor packages including package substrates having polymer-derived ceramic cores are described. In an example, a package substrate includes a core layer including a polymer-derived ceramic. The polymer-derived ceramic may include filler particles to control shrinkage and reduce warpage of the core layer during fabrication and use of the package substrate. The core layer may include counterbores or blind holes to embed a contact pad or an electrical interconnect in the core layer. A semiconductor die may be mounted on the package substrate and may be electrically connected to the contact pad or the electrical interconnect.

  • Patent number: 10384431
    Abstract: A method for forming a substrate structure for an electrical component includes placing an electrically insulating laminate on a substrate and applying hot pressure to the electrically insulating laminate by a heatable plate. An average temperature of a surface temperature distribution within a center area of the heatable plate is higher than 80° C. during applying the hot pressure. Further, an edge area of the heatable plate laterally surrounds the center area and a temperature of the heatable plate within the edge area decreases from the center area towards an edge of the heatable plate during applying the hot pressure. A temperature at a location located vertically above an edge of the substrate during applying the hot pressure is at least 5° C. lower than the average temperature of the surface temperature distribution within the center area.
