  • Patent number: 11957061
    Abstract: A semiconductor device includes a substrate, a first dielectric layer, a second dielectric layer, and a third dielectric layer. The first dielectric layer is disposed on the substrate, around a first metal interconnection. The second dielectric layer is disposed on the first dielectric layer, around a via and a second metal interconnection. The second metal interconnection directly contacts the first metal interconnection. The third dielectric layer is disposed on the second dielectric layer, around a first magnetic tunneling junction (MTJ) structure and a third metal interconnection. The third metal interconnection directly contacts top surfaces of the first MTJ structure and the second metal interconnection, and the first MTJ structure directly contacts the via.

  • Publication number: 20240113032
    Abstract: Interconnect structure packages (e.g., through silicon vias (TSV) packages, through interlayer via (TIV) packages) may be pre-manufactured as opposed to forming TIVs directly on a carrier substrate during a manufacturing process for a semiconductor die package at backend packaging facility. The interconnect structure packages may be placed onto a carrier substrate during manufacturing of a semiconductor device package, and a semiconductor die package may be placed on the carrier substrate adjacent to the interconnect structure packages. A molding compound layer may be formed around and in between the interconnect structure packages and the semiconductor die package.

  • Publication number: 20240098833
    Abstract: A method for mobility enhancement in wireless communication systems is provided. The method is performed by a User Equipment (UE) configured with a first Small Data Transmission (SDT) configuration by a first cell. The method includes receiving a Radio Resource Control (RRC) release message including a suspend configuration from the first cell; transitioning to an RRC INACTIVE state in response to receiving the RRC release message; receiving, in the RRC INACTIVE state, a System Information Block Type 1 (SIB1) including a second SDT configuration from a second cell; camping on the second cell in response to receiving the SIB1 from the second cell; and while the UE is camping on the second cell, refraining from using the first SDT configuration to initiate an SDT procedure associated with the second cell in a case that the UE does not support performing the SDT procedure associated with the second cell.
