Abstract

Abstract Translated from Japanese (57)【要約】 【課題】アンテナとICチップの接続を容易に行えると ともに、アンテナのターン数を増やすことのできる電子 回路基板及びその製造方法を提供することにある。 【解決手段】電子回路基板は、コイル状アンテナ20 と、アンテナ20を跨ぐようにして配置され、アンテナ の始点及び終点にそれぞれ接続端子を介して接続された 半導体ICチップ30とから構成される。コイル状アン テナは、回路基材10の表面に形成された複数の基材側 のアンテナ用導体膜20と、半導体ICチップ30の接 続端子が設けられた面に形成された複数のチップ側のア ンテナ用導体膜32とから構成される。 (57) Abstract: An object of the present invention is to provide an electronic circuit board capable of easily connecting an antenna to an IC chip and increasing the number of turns of the antenna, and a method of manufacturing the same. An electronic circuit board includes a coiled antenna. And a semiconductor IC chip 30 arranged so as to straddle the antenna 20 and connected to the start point and the end point of the antenna via connection terminals, respectively. The coil-shaped antenna includes a plurality of substrate-side antenna conductor films 20 formed on the surface of the circuit substrate 10 and a plurality of chip-side antennas formed on the surface of the semiconductor IC chip 30 on which connection terminals are provided. And the conductive film 32 for use.
