【発明の属する技術分野】
本発明は、基板のアンテナ部と半導体装置の金属突起との間隔を一定に保つことにより、特性のバラツキを小さくすることができ、その結果、製品の歩止まりを向上させることができる半導体モジュールとそれを備えた非接触ICタグ及び半導体モジュールの製造方法に関するものである。
【0002】
【従来の技術】
近年、交通、流通、情報通信等の分野においては、ダイポールアンテナ等の無線通信用のアンテナ部及び配線パターンが形成された回路基板上に、複数のバンプ電極(金属突起)を有するICチップ(半導体装置)を搭載した半導体モジュールが提案されている。
この半導体モジュールは、ICチップによる高い情報処理能力を有し、情報の書き込みや読み出しを非接触にて高速で行うことができ、しかも、高いセキュリティ機能を有するという特徴があることから、交通システムにおける乗車券、書籍、CD、DVD等の情報媒体の商品管理に用いられるICタグ、オフィスビルやマンション等における非接触型のIDカードやカードキー等様々な分野で広く利用されている(例えば、特許文献1参照)。

【0004】
図3は、従来の半導体モジュールを示す平面図、図4は同断面図であり、図において、符号1は回路基板、2は回路基板1上に形成されたダイポールアンテナ(アンテナ部)、3はこれらのダイポールアンテナ2、2に圧接されたICチップ(半導体装置)、4はICチップ3のバンプ電極(金属突起)、5はICチップ3をダイポールアンテナ2、2を含む回路基板1上に固定する熱硬化型樹脂である。この熱硬化型樹脂5は、例えば、紫外線硬化型等の光硬化型樹脂であってもよい。
この半導体モジュールは、製品の軽薄短小化、高密度化に適したフリップチップ実装方式を用いてICチップ3のバンプ電極4、4を回路基板1上のダイポールアンテナ2、2に圧接している。
【0005】
【発明が解決しようとする課題】
ところで、上述した従来の半導体モジュールでは、ICチップ3を回路基板1上のダイポールアンテナ2、2に圧接し固定する際に、ICチップ3のバンプ電極4、4と回路基板1上のダイポールアンテナ2、2との間に熱硬化型樹脂5が残った状態で両者を接続しているために、このICチップ3のバンプ電極4、4と回路基板1上のダイポールアンテナ2、2との間に残る熱硬化型樹脂5の厚みにバラツキが生じ易いという問題点があった。この厚みのバラツキを解消するには、圧接時の圧力をコントロールすればよいのであるが、圧力を高精度でコントロールすることは難しい。また、厚みのバラツキが大きかった場合、ICチップ3のバンプ電極4、4と回路基板1上のダイポールアンテナ2、2との間の容量Cが変化してしまい、その結果、高周波の発信特性のバラツキが大きくなり、製品としての歩留まりが低下するという問題点があった。
【0006】
本発明は、上記課題を解決するためになされたものであって、基板のアンテナ部と半導体装置の金属突起との間隔を一定に保つことにより、特性のバラツキを小さくすることができ、その結果、製品の歩止まりを向上させることができる半導体モジュールとそれを備えた非接触ICタグ及び半導体モジュールの製造方法を提供することを目的とする。

【0015】
【発明の実施の形態】
本発明の半導体モジュールとそれを備えた非接触ICタグ及び半導体モジュールの製造方法の一実施形態について図面に基づき説明する。
図1は、本実施形態の半導体モジュールを示す断面図であり、この半導体モジュールは、ダイポールアンテナ(アンテナ部)2が形成された回路基板1上に、複数のバンプ電極(金属突起)4、11、…を有するICチップ(半導体装置)12が搭載されている。
【0016】
このICチップ12のバンプ電極4(図1では、一方のみ図示)及びICテスト用のバンプ電極11は、バンプ電極4の少なくともダイポールアンテナ2との接続領域、及びバンプ電極11のICテスタの端子との接続領域を除いて、パシベーション膜(保護・絶縁膜)13により覆われている。すなわち、このパシベーション膜13には、ダイポールアンテナ2との接続領域であるバンプ電極4の略中央部を露出させるための開口13a、及びバンプ電極11の略中央部を露出させるための開口13bが形成されている。
【0017】
ICチップ12は、集積回路(IC)の一方の主面上に複数の電極が形成されたもので、例えば、非接触ICタグ用のICチップを用いる。この非接触ICタグ用のICチップとは、送受信回路、制御回路、メモリ等を構成する集積回路(IC)が形成された半導体チップであり、ダイポールアンテナあるいはコイル状アンテナと接続することにより、外部の情報機器とデータの送受信が行えるようになっている。
【0018】
パシベーション膜13は、ICチップ12の集積回路(IC)及び複数の電極を保護するために設けられたもので、絶縁性を有するものであればとくに限定されないが、例えば、ポリイミド樹脂、エポキシ樹脂、シリコーン樹脂等の合成樹脂が好適に用いられる。また、この合成樹脂としては、熱により硬化する熱硬化型樹脂、あるいは紫外線等の光により硬化する光硬化型樹脂が好適である。
【0019】
このバンプ電極4とダイポールアンテナ2との間には微粒子混入樹脂14が充填されている。
この微粒子混入樹脂14は、絶縁性を有する液状またはシート状の樹脂を熱あるいは紫外線等の光により硬化させた絶縁性樹脂15中に非導電性微粒子16を混入・分散させたもので、絶縁性樹脂15としては、絶縁性、機械的強度及び耐摩耗性等に優れているエポキシ樹脂、メラミン樹脂、フェノール樹脂、アクリル樹脂、シリコーン樹脂等が好適に用いられ、また、非導電性微粒子16としては、酸化ケイ素、酸化アルミニウム、タルク等のセラミックス微粒子、またはポリイミド、ポリアミド、フッ素樹脂等の絶縁性樹脂15より軟化点温度が高い合成樹脂微粒子が好適に用いられる。これらの微粒子は、粒子径が揃った単分散微粒子が好ましい。
【0020】
この半導体モジュールでは、バンプ電極4とダイポールアンテナ2との間に、絶縁性樹脂15中に単分散の非導電性微粒子16を混入・分散させた微粒子混入樹脂14を充填したことにより、非導電性微粒子16がスペーサとなってバンプ電極4とダイポールアンテナ2との間の間隔が一定に保持される。これにより、微粒子混入樹脂14の厚みは非導電性微粒子16の直径により制御され、厚みのバラツキが極めて小さくなり、圧接時の圧力をコントロールする必要も無くなる。
【0021】
この微粒子混入樹脂14の厚みは、非導電性微粒子16の直径により概ね決定されるものであるから、特に厚みを制御する必要はないが、非接触ICタグとして用いる場合には、ICチップ12のバンプ電極4とダイポールアンテナ2との間の容量分Cで結合することができる厚みであることが必要である。
例えば、2.45GHz帯域の高周波を用いる場合、1μm〜数10μmが好ましい。この厚みは面方向に一定であることが好ましい。
【0022】
このICチップ12を用いた非接触ICタグの例としては、書籍、CD、DVD等の情報媒体の商品管理に用いられる非接触型のICタグがあり、このICタグをIDカード等に埋め込めば、個人の識別ができるIDカードとして用いることもできる。
【0023】
例えば、非接触ICタグ用に用いた場合のダイポールアンテナ2のアンテナ長Lは、高周波の波長をλ、光速をC、高周波の周波数をfとすると、
L=λ/2=C/(2×f)
で表される。
ここで、光速Cを2.99×108m、高周波の周波数fを2.45GHz=2.45×109Hzとすると、
となる。したがって、タグサイズに充分対応することができる。
【0024】
次に、この半導体モジュールの製造方法について説明する。
まず、図2(a)に示すように、回路基板1のダイポールアンテナ2上のICチップ12搭載位置に、樹脂21を塗布する。
この樹脂21は、絶縁性を有する液状またはシート状の樹脂中に、酸化ケイ素微粒子、合成樹脂微粒子等の非導電性微粒子を混入・分散させたもので、熱あるいは紫外線等の光により硬化し、絶縁性を有する。
【0025】
次いで、ICチップ12のバンプ電極4と、回路基板1のダイポールアンテナ2との位置合わせを行う。
次いで、図2(b)に示すように、ICチップ12に上方から所定の圧力Fを加え、このICチップ12をダイポールアンテナ2に所定の圧力Fで圧接する。
この状態で、樹脂21に対して熱あるいは紫外線等の光を加える。これにより樹脂21は硬化して絶縁性を有する微粒子混入樹脂14となる。
以上により、半導体モジュールを製造することができる。
【0026】
以上説明したように、本実施形態の半導体モジュールによれば、ICチップ12のバンプ電極4と、回路基板1上のダイポールアンテナ2との間に、絶縁性樹脂15中に非導電性微粒子16を混入・分散させた微粒子混入樹脂14を充填したので、回路基板1上のダイポールアンテナ2とICチップ12のバンプ電極4との間隔を一定に保つことができ、発信特性等のバラツキを小さくすることができる。その結果、製品の歩止まりを向上させることができる。
【0027】
また、本実施形態の半導体モジュールの製造方法によれば、回路基板1のダイポールアンテナ2上のICチップ12搭載位置に、非導電性微粒子を混入・分散させた熱硬化型あるいは紫外線等の光硬化型の絶縁性を有する樹脂21を塗布し、ICチップ12のバンプ電極4を樹脂21を介して回路基板1のダイポールアンテナ2に圧接するので、回路基板1上のダイポールアンテナ2とICチップ12のバンプ電極4との間隔が高精度で一定に保持された半導体モジュールを、簡単な工程で、しかも容易に作製することができる。その結果、発信特性等のバラツキが小さく、製品の歩止まりが向上した半導体モジュールを容易に作製することができる。
【0028】
また、本実施形態の半導体モジュールを用いて非接触ICタグを作製すれば、発信特性等のバラツキが小さく、製品の歩止まりの高い非接触ICタグを得ることができる。
【0029】
【発明の効果】
以上説明したように、本発明の半導体モジュールによれば、アンテナ部が形成された基板上に、複数の金属突起を有する半導体装置を搭載してなる半導体モジュールであって、前記半導体装置の少なくとも1対の金属突起を、非導電性微粒子を混入してなる樹脂を介して前記アンテナ部に接続したので、基板のアンテナ部と半導体装置の金属突起との間隔を一定に保つことができ、特性のバラツキを小さくすることができる。
また、特性のバラツキが小さいので、信頼性、特に長期間使用時の信頼性を高めることができる。
【0030】
本発明の非接触ICタグによれば、本発明の半導体モジュールを備えたので、発信特性等のバラツキが小さく、製品の歩止まりの高い非接触ICタグを得ることができる。
【0031】
本発明の半導体モジュールの製造方法によれば、基板上のアンテナ部の半導体装置の金属突起との接続領域に、非導電性微粒子を混入してなる樹脂層を形成する工程と、該樹脂層上に前記半導体装置の金属突起を載置し、該半導体装置の金属突起を前記樹脂層を介して前記アンテナ部に圧接する工程とを有するので、基板のアンテナ部と半導体装置の金属突起との間隔が一定に保持され、しかも特性のバラツキの小さい半導体モジュールを、容易に製造することができる。
また、バラツキが小さいので、製品の歩留まりが高くなり、信頼性の向上及び製造方法コストの低減を図ることができる。
