Abstract: Disclosed are a packaging substrate and a semiconductor device. The semiconductor device comprises an element unit comprising a semiconductor element and a packaging substrate electrically connected to the element unit. By applying a glass substrate to the packaging substrate as a core substrate, connecting the semiconductor element and a motherboard can be closer to each other, so that electrical signals are transferred through as short a path, and significantly improved electrical properties such as a signal transfer rate could be achieved. Also, it is possible to prevent an occurrence of a parasitic element effect and to apply to a high-speed circuit device without additional insulating process.
