  • Patent number: 11961775
    Abstract: In one example, a semiconductor device can comprise a substrate, a device stack, first and second internal interconnects, and an encapsulant. The substrate can comprise a first and second substrate sides opposite each other, a substrate outer sidewall between the first substrate side and the second substrate side, and a substrate inner sidewall defining a cavity between the first substrate side and the second substrate side. The device stack can be in the cavity and can comprise a first electronic device, and a second electronic device stacked on the first electronic device. The first internal interconnect can be coupled to the substrate and the device stack. The encapsulant can cover the substrate inner sidewall and the device stack and can fill the cavity. Other examples and related methods are disclosed herein.

  • Publication number: 20240079550
    Abstract: Provided is a flexible air supply damper system for preventing an overdrying-caused defect of a secondary battery electrode plate, the flexible air supply damper system including: a fluid supply unit supplying a fluid; a heating unit heating the fluid supplied through the fluid supply unit; a drying unit drying the electrode plate while receiving the fluid heated through the heating unit; a damper unit splitting the fluid passing through the heating unit to control an amount of the fluid to be introduced into the drying unit; and a discharge unit through which the fluid used in the drying unit and the fluid split out of the damper unit are discharged. By controlling the amount of the fluid to be introduced into the drying unit, the electrode plate is prevented from being overdried.
