  • Publication number: 20230016186
    Abstract: A semiconductor device includes a substrate. A conductive layer is disposed on the substrate and extends in a first direction. An insulating layer is disposed on the conductive layer and exposes at least a portion of the conductive layer through a via hole. The via hole includes a first face extending in a first slope relative to a top face of the conductive layer. A second face extends in a second slope relative to the top face of the conductive layer that is less than the first slope. A redistribution conductive layer includes a first pad area disposed in the via hole. A line area at least partially extends along the first face and the second face. The first face directly contacts the conductive layer. The second face is positioned at a higher level than the first face in a second direction perpendicular to a top face of the substrate.

  • Patent number: 7860645
    Abstract: The telematics service providing system generates a path from the departure point to the destination based on traffic information, generates guidance information for each guidance point where a turn to a direction that is different from the current progress direction of the client is needed on the generated path, clips a vicinity map covering a predetermined area with reference to the guidance point from the total map to generate a guidance point vicinity map, converts the generated guidance point vicinity map into a format displayable by the client, and provides the converted map to the client terminal. Accordingly, confusion caused by complex crossroads or paths that need consecutive and same direction turns may be prevented, the client terminal may not need a memory for storing large-volume geographic information data, and the client may not additionally need to upgrade the geographic information data.
