Patent ID: 10269734

Abstract:
A semiconductor element that has an element first main surface, an element second main surface that is the reverse surface from the element first main surface, and an element side surface. The semiconductor element is configured from a semiconductor substrate part and an insulating layer part and is provided with: a signal transmission/reception terminal that is provided to the element first main surface and that contacts and can transmit/receive signals to/from an external-substrate signal transmission/reception terminal that is provided to an external substrate that is external to the semiconductor element; and a signal transmission/reception coil that is provided to the element side surface and that, via the element side surface, can transmit/receive signals in a non-contact manner to/from an external-semiconductor-element signal transmission/reception part that is provided to an external semiconductor element that is external to the semiconductor element. The signal transmission/reception coil has: a conductor that is formed inside the insulating layer part; and a conductor that is formed inside the semiconductor substrate part.
