  • Publication number: 20220328622
    Abstract: A method of forming a semiconductor device structure is provided. The method includes forming an insulating layer over a semiconductor substrate including a conductive feature, forming an insulating layer with a trench over the semiconductor substrate to expose the conductive feature, and forming a sacrificial liner layer over two opposite sidewalls and a bottom of the trench. Ions are implanted into the conductive feature covered by the sacrificial liner layer, so that a doping region is formed in the conductive feature and has two opposite side edges respectively separated from the two opposite sidewalls of the trench. The sacrificial liner layer is removed after forming the doping region, and a conductive connecting structure is formed in the trench. The two opposite sidewalls of the conductive connecting structure are respectively separated from the two corresponding opposite sidewalls of the trench by an air spacer.

  • Patent number: 11330457
    Abstract: A beam indication (BI) mechanism is proposed to provide user equipment (UE) information of network (NW) beam(s) for later transmission. UE can then select its UE beam(s) for the later transmission based on the BI. In one embodiment, NW provides beam management configuration to UE via Radio Resource Control (RRC) signaling, and then provides beam indication index signaling to UE via MAC-CE or DCI. The beam management configuration comprises a mapping table between network beams and configured reference signal (RS) resources. The beam indication index signaling indicates one or more preferred beam pair links (BPLs). Upon triggering a beam management procedure by the network, UE is able to identify the beam management procedure and selects corresponding UE beam(s) based on the beam management configuration and the beam indication index signaling.
