    摘要: An interconnection structure and a method of fabricating the same are provided. The interconnection structure includes an interlayer insulating layer having a structure comprising a via hole structure or a trench-shaped line structure. A conformal metal diffusion barrier layer is disposed inside the via hole structure or the trench-shaped line structure of the interlayer insulating layer. An insulating diffusion barrier spacer is disposed to cover the metal diffusion barrier layer on the sidewalls of the via hole structure or the trench-shaped line structure of the interlayer insulating layer. In addition, a copper interconnection is disposed to fill the inside of the via hole structure or the trench-shaped line structure of the interlayer insulating layer.

    摘要: Methods of fabricating a microelectronic device having improved performance characteristics are disclosed which are characterized by using super critical fluid to perform a material removal step. In one illustrative embodiment, the method includes preparing a substrate, forming an HSQ layer covering at least a portion of the substrate, and thereafter removing at least portions of the HSQ layer using super critical fluid CO2.

    摘要: A handoff method between a source network to which a terminal is connected in order of a Base Station (BS) and an Access Service Network (ASN), and a target network to which the terminal is connected in order of a Packet Data Service Node (PDSN), a Packet Control Function (PCF) and an Access Network (AN). The terminal sends a handoff request message with AN information of the target network to the ASN via the BS. The ASN forwards the handoff request message to the PCF via the PDSN using the AN information. Upon receipt of the handoff request message, the PCF sends a request for session information to the ASN via the PDSN. The PDSN sends a request for context information to the ASN. Upon receipt of the session information request and the context information request, the ASN transfers the context information to the PDSN and transfers the session information to the AN via the PDSN and the PCF.

    摘要: In a method for filling a hole with a metal, an insulating layer, a first mask layer and a second mask layer are successively formed on a semiconductor substrate. The first and second mask layers are etched using a photoresist pattern to form first and second masks. The first mask layer pattern is selectively etched using an etchant, the first mask layer pattern having a higher etching selectivity than the second layer pattern with respect to the etchant, to form a third mask layer pattern having a broadened opening. The insulating layer is etched using the second mask to form a hole in the insulating layer. A metal layer is formed in the hole and the third opening. The metal layer is planarized to form a metal plug buried in the hole without recesses or voids.

    摘要: A method of forming a conductive pattern includes preparing a semiconductor substrate having a conductive pattern, forming an interlayer dielectric pattern having an opening exposing the conductive pattern on the semiconductor substrate, forming a metal layer on the interlayer dielectric pattern to fill the opening, wet etching the metal layer, and polishing the metal layer to form a metal pattern filling the opening. The wet etching is done such that a top surface of the interlayer dielectric pattern is not exposed.
