Abstract
【解決手段】at.%で、Bを10〜50%含有し、残部がCoとFeの少なくとも1種、不可避的不純物からなるスパッタリングターゲット材において、(CoFe)2B(200)のX線回折強度[I〔(CoFe)2B〕]と(CoFe)3B(121)のX線回折強度[I〔(CoFe)3B〕]との強度比[I〔(CoFe)3B〕/I〔(CoFe)2B〕]が1.50以下であるCoFeB系合金スパッタリングターゲット材。

Description
(1)at.%で、Bを10〜50%含有し、残部がCoとFeの少なくとも1種、不可避的不純物からなるスパッタリングターゲット材において、(CoFe)2 B(200)のX線回折強度[I〔(CoFe)2 B〕]と(CoFe)3 B(121)のX線回折強度[I〔(CoFe)3 B〕]との強度比[I〔(CoFe)3 B〕/I〔(CoFe)2 B〕]が1.50以下であるCoFeB系合金スパッタリングターゲット材。
本発明に係る成分組成として、Bを10〜50原子%とした理由は、10%以下ではスパッタ時、十分な非晶質とならず、50%を超えると本発明の効果に関係なく、スパッタ時のパーティクルを低減することができないために、その範囲を10〜50%とする。好ましくは20〜50%とする。また、CoとFeは磁性を付与するもので、CoとFeとの合計含有量を50原子%以上とする。なお、その他の不純物は1000ppmまで含んでもよい。
