Abstract
Description
ここに、本発明は次の通りである。
Cuカラム1の算術平均粗さは、0.3μm以下であり、より好ましくは、0.2μm以下である。Cuカラム1の算術平均粗さが0.3μm以下である場合、Cuカラム1の結晶粒の大きさも小さくなるので、Cuカラム1の表面をより滑らか(平坦)にすることができる。これにより、Cuカラム1をマウンター等により基板上に配列する際のCuカラム1の流動性を向上させることができると共に、実装時におけるCuカラム1と基板上の電極の密着性の向上を図ることもできる。
本発明に係るCuカラム1のビッカース硬さは、60HV以下であることが好ましい。ビッカース硬さが60HV以下である場合、外部からの応力に対する耐久性が高くなり、耐落下衝撃性が向上すると共にクラックが発生しにくくなるからである。また、三次元実装のバンプや継手の形成時に加圧等の補助力を付与した場合において、柔軟性の高いCuカラム1を使用することで、電極潰れ等を引き起こす可能性を低下させることができるからである。
UおよびThは放射性元素であり、ソフトエラーを抑制するにはこれらの含有量を抑える必要がある。UおよびThの含有量は、Cuカラム1のα線量を0.0200cph/cm2以下とするため、各々5ppb以下にする必要がある。また、現在または将来の高密度実装でのソフトエラーを抑制する観点から、UおよびThの含有量は、好ましくは、各々2ppb以下である。
本発明を構成するCuカラム1は純度が99.9%以上99.995%以下であることが好ましい。Cuカラム1の純度がこの範囲であると、十分な量の不純物元素の結晶核をCu中に確保することができるので、Cuカラム1の算術平均粗さを小さくできる。一方、不純物元素が少ないと、相対的に結晶核となるものが少なく、粒成長が抑制されずにある方向性をもって成長するので、Cuカラム1の算術平均粗さが大きくなってしまう。Cuカラム1の純度の下限値は特に限定されないが、α線量を抑制し、純度の低下によるCuカラム1の電気伝導度や熱伝導率の劣化を抑制する観点から、好ましくは99.9%以上である。不純物元素としては、Sn、Sb、Bi、Zn、As、Ag、Cd、Ni、Pb、Au、P、S、In、Co、Fe、U、Thなどが挙げられる。
本発明を構成するCuカラム1のα線量は、0.0200cph/cm2以下である。これは、電子部品の高密度実装においてソフトエラーが問題にならない程度のα線量である。α線量は、更なる高密度実装でのソフトエラーを抑制する観点から、より好ましくは0.0010cph/cm2以下である。
本発明を構成するCuカラム1は、不純物元素としてSn、Sb、Bi、Zn、As、Ag、Cd、Ni、Pb、Au、P、S、In、Co、Fe、U、Thなどを含有するが、不純物元素の含有量が合計で1ppm以上含有する。なお、不純物元素であるPbおよびBiの含有量は、極力低い方が好ましい。
本発明に係るCuカラム1の上面および底面の径φは1〜1000μmであることが好ましく、特にファインピッチに用いる場合は1〜300μがより好ましく、さらに好ましくは1〜200μmであり、最も好ましいのは1〜100μmである。そして、Cuカラム1の高さLは1〜3000μmであることが好ましく、特にファインピッチに用いる場合は1〜300μがより好ましく、さらに好ましくは1〜200μmであり、最も好ましいのは1〜100μmである(図1参照)。Cuカラム1の径φおよび高さLが上記範囲である場合、端子間を狭ピッチとした実装が可能となるので、接続短絡を抑制することができると共に半導体パッケージの小型化および高集積化を図ることができる。
純度が99.9%、99.99%、99.995%の銅線を準備した。次に、これら銅線をダイスを通過させることにより、上面および底面の径φが200μmとなるように銅線を伸ばし、その後、200μmの長さ(高さL)となる位置にて銅線を切断することにより、目的とするCuカラムを作製した。
Cuカラムの算術平均粗さの評価(画像評価)は、KEYENCE社製のレーザ顕微鏡(型番VK−9510/JISB0601−1994対応)を使用して行った。本実施例では、Cuカラムの上面の最も平坦な部分を中心として、10×10μmの範囲で測定した。Cuカラムのz軸上(高さ方向)における測定ピッチは0.01μmである。このような条件でCuカラムの算術平均粗さRaとして、任意の10個所の算術平均粗さRaを測定し、それらの算術平均を真の算術平均粗さとして使用した。
Cuカラムのビッカース硬さは、「ビッカース硬さ試験−試験方法 JIS Z2244」に準じて測定した。装置は、明石製作所製のマイクロビッカース硬度試験器、AKASHI微小硬度計MVK−F 12001−Qを使用した。
α線量の測定方法は以下の通りである。α線量の測定にはガスフロー比例計数器のα線測定装置を使用した。測定サンプルは300mm×300mmの平面浅底容器にCuカラムを容器の底が見えなくなるまで敷き詰めたものである。この測定サンプルをα線測定装置内に入れ、PR−10ガスフローにて24時間放置した後、α線量を測定した。
純度99.9%の銅線を使用して製造したCuカラムをカーボン製バットに入れた後、このバットを連続コンベア式電気抵抗加熱炉に搬入してアニーリング処理を行った。このときの、アニーリング条件を図3に示す。なお、炉内は、Cuカラムの酸化を防止するために窒素ガス雰囲気にした。室温は25℃とした。
実施例2では、純度が99.99%の銅線により作製されたCuカラムに対し、実施例1と同様の方法により、アニーリング処理を行うと共に酸化膜除去処理を行った。そして、得られたCuカラムのビッカース硬さ、算術平均粗さおよびα線量を測定した。これらの測定結果を下記表1に示す。
比較例1では、純度が99.9%の銅線により作製されたCuカラムのビッカース硬さ、算術平均粗さおよびα線量をそれぞれ測定した。これらの測定結果を下記表1に示す。
比較例2では、純度が99.99%の銅線により作製されたCuカラムのビッカース硬さ、算術平均粗さおよびα線量をそれぞれ測定した。これらの測定結果を下記表1に示す。

比較例4では、純度が99.995%を超える銅線により作製されたCuカラムのビッカース硬さ、算術平均粗さおよびα線量をそれぞれ測定した。これらの測定結果を下記表1に示す。
比較例5では、純度が99.995%を超える銅線により作製されたCuカラムに対し、実施例1と同様の方法により、アニーリング処理を行うと共に酸化膜除去処理を行った。そして、得られたCuカラムのビッカース硬さ、算術平均粗さおよびα線量を測定した。これらの測定結果を下記表1に示す。
