    Abstract: A method for processing a substrate is disclosed. The method includes delivering a solvent to a processing chamber and delivering a substrate to the processing chamber. The amount of solvent present in the processing chamber may be configured to submerse the substrate. Liquid CO2 may be delivered to the processing chamber and the liquid CO2 may be mixed with the solvent. Additional liquid CO2 may be delivered to the processing chamber in an amount greater than a volume of the processing chamber to displace the solvent. The liquid CO2 may be phase transitioned to supercritical CO2 in the processing chamber and the substrate may be dried by isothermally depressurizing the processing chamber and exhausting gaseous CO2 from the processing chamber.

    Abstract: A substrate support apparatus is provided. The apparatus includes a circular base plate and one or more spacers disposed about a circumference of the base plate. The spacers may extend from a top surface of the base plate and a ring body may be coupled to the spacers. The ring body may be spaced from the base plate to define apertures between the base plate and the ring body. One or more support posts may be coupled to the base plate and extend therefrom. The support posts may be coupled to the base plate at positions radially inward from an inner surface of the ring body.

    Abstract: A method and apparatus for forming a plurality of vias in panels for advanced packaging applications is disclosed, according to one embodiment. A redistribution layer is deposited on a substrate layer. The redistribution layer may be deposited using a spin coating process, a spray coating process, a drop coating process, or lamination. The redistribution layer is then micro-imprinted using a stamp inside a chamber. The redistribution layer and the stamp are then baked inside the chamber. The stamp is removed from the redistribution layer to form a plurality of vias in the redistribution layer. Excess residue built-up on the redistribution layer may be removed using a descumming process. A residual thickness layer disposed between the bottom of each of the plurality of vias and the top of the substrate layer may have thickness of less than about 1 μm.

    Abstract: Embodiments of the present disclosure generally describe methods for minimizing the occurrence and the extent of die shift during the formation of a reconstituted substrate in fan-out wafer level packaging processes. Die shift is a process defect that occurs when a die (device) moves from its intended position within a reconstituted substrate during the formation thereof. Generally, the methods disclosed herein include depositing a device immobilization layer and/or a plurality of device immobilization beads over and/or adjacent to a plurality of singular devices (individual dies), and the carrier substrate they are positioned on, before forming a reconstituted substrate with an epoxy molding compound. The device immobilization layer and/or the plurality of device immobilization beads immobilize the plurality of singular devices and prevents them from shifting on the carrier substrate during the molding process.

    Abstract: A method and apparatus for forming a magnetic layer having a pattern of magnetic properties on a substrate is described. The method includes using a metal nitride hardmask layer to pattern the magnetic layer by plasma exposure. The metal nitride layer is patterned using a nanoimprint patterning process with a silicon oxide pattern negative material. The pattern is developed in the metal nitride using a halogen and oxygen containing remote plasma, and is removed after plasma exposure using a caustic wet strip process. All processing is done at low temperatures to avoid thermal damage to magnetic materials.
