Claims
- 1. A noncontact communication semiconductor device characterized by comprising an IC having a three-dimensional circuit-forming surface and a radio communication antenna formed as a three-dimensional pattern on the surface of said IC.
- 2. A noncontact communication semiconductor device as described in claim 1, characterized in that said IC has a curved contour surface.
- 3. A noncontact communication semiconductor device as described in claim 2, characterized in that said IC is spherical.
- 4. A noncontact communication semiconductor device as described in claim 1, characterized in that an insulating layer is interposed between said IC and said antenna.
- 5. A noncontact communication semiconductor device characterized by comprising an IC having a three-dimensional circuit-forming surface and a radio communication antenna attached on the outer peripheral surface of said IC and electrically connected to the input/output terminals of the circuit formed three-dimensionally on said circuit-forming surface, wherein said antenna is configured with two conductive hollow hemispherical members, and the peripheral edge portions of these two conductive hollow hemispherical members are arranged in opposed relation to each other through a predetermined slit.
- 6. A noncontact communication semiconductor device characterized by comprising an IC having a three-dimensional circuit-forming surface and a radio communication antenna attached on the outer peripheral surface of said IC and electrically connected to the input/output terminals of the circuit formed three-dimensionally on said circuit-forming surface, wherein said antenna is configured with a conductive hollow spherical member having a slit in a portion thereof.
