Abstract: A semiconductor device includes a conductive structure on a substrate, an etch stop layer on the conductive structure, an insulation layer on the etch stop layer, and a contact plug extending through the etch stop layer and the insulation layer and contacting the conductive structure. The contact plug may include first and second conductive pattern structures sequentially stacked and contacting with each other. A width of an upper surface of the first conductive pattern structure may be greater than that of a lower surface of the second conductive pattern structure. At least an upper portion of the first conductive pattern structure may have a sidewall not perpendicular but inclined to an upper surface of the substrate.

Abstract: The present disclosure relates to a 5G or pre-5G communication system for supporting higher data transmission rates beyond 4G communication systems such as LTE systems. A method for establishing a plurality of protocol data unit (PDU) sessions between a user equipment (UE) and a data network (DN) by the UE may comprise transmitting a message to establish the plurality of PDU sessions to at least one network function (NF) of a plurality of NFs, exchanging a signal to establish the plurality of PDU sessions among the UE, a radio access network (RAN), and the plurality of NFs based on the message, and establishing the plurality of PDU sessions between the UE and the DN according to predetermined priority and based on the signal, wherein each of the plurality of PDU sessions corresponds to a network slice (NS) for a particular service, wherein the message includes information about the particular service corresponding to the plurality of PDU sessions, and wherein the priority is determined based on the information about the particular service.
