Abstract
Description
ところが、上述した三次元実装される半導体デバイスの製造工程においては、半導体基板上の薄膜測定のみならず、半田バンプを測定対象に加えたいという新たなニーズが生まれている。
X線照射ユニットは、試料に含まれる複数の元素のうち測定対象に選定した測定対象元素と、当該元素よりもエネルギ吸収端の値が大きい隣接元素とに着目し、測定対象元素のエネルギ吸収端よりも大きく、且つ隣接元素のエネルギ吸収端以下の値を示すエネルギをもつX線を、試料に照射する構成であることを特徴とする。
そのため、試料中の含有量が少ないことが原因で従来の技術では高精度な測定が困難な元素についても、高精度に測定することが可能となる。
このようなX線を試料に照射することで、測定対象元素に対するX線の励起効率が上がり、測定対象元素から多くの蛍光X線が放出される。
すなわち、X線照射ユニットは、測定対象元素に選定したAgのエネルギ吸収端よりも値が大きく、且つ当該Agよりもエネルギ吸収端の値が大きい隣接元素でもあるSnのエネルギ吸収端以下の値を示すエネルギをもつX線と、測定対象元素に選定したSnのエネルギ吸収端よりも大きい値のエネルギのX線とを、試料に照射するように構成する。
そして、X線照射ユニットからのX線が照射される試料のX線照射部位に対し、その周囲に、当該試料から放出される蛍光X線を取り込む姿勢で、複数のX線検出器を配置する。それら各X線検出器は個別に移動自在とする。
さらに、複数のX線検出器のうち、試料から回折してきた回折X線を検出したX線検出器を、当該回折X線が入射しない位置へ移動させる制御部を備えた構成とする。
すなわち、X線照射ユニットからのX線が照射される試料のX線照射部位に対し、その周囲に、当該試料から放出される蛍光X線を取り込む姿勢で、複数のX線検出器を配置する。試料と各X線検出器との間には、X線を遮蔽するX線遮蔽扉をそれぞれ開閉自在に設ける。
そして、複数のX線検出器のうち、試料から回折してきた回折X線を検出したX線検出器に対し、X線遮蔽扉を閉塞する制御部を備えた構成とする。
すなわち、X線照射ユニットからのX線が照射される試料のX線照射部位に対し、その周囲に、当該試料から放出される蛍光X線を取り込む姿勢で、複数のX線検出器を配置する。さらに、複数のX線検出器のうち、試料から回折してきた回折X線を検出したX線検出器からの検出信号を除外し、それ以外のX線検出器からの検出信号に基づいて蛍光X線分析を行う分析部を備えた構成とする。

以下の実施形態では、三次元実装される半導体基板(半導体ウエハ)に設けられた半田バンプの検査に好適な蛍光X線分析装置の構成を説明するが、本発明の用途はこれに限定されないことは勿論である。
まず、図1A~図5を参照して、本発明の第1実施形態に係る蛍光X線分析装置を説明する。
図1A,図1B及び図2に示すように、本実施形態に係る蛍光X線分析装置は、試料台10、試料位置決め機構11、X線照射ユニット20、X線検出ユニット30の各構成要素を備えている。
試料台10の表面には、試料(半導体基板)Sが配置される。
試料位置決め機構11は、試料台10を駆動して、試料台10に配置された試料Sにおける被測定箇所(すなわち、X線照射部位)を、X線照射ユニット20から照射されるX線の収束点に位置決めする構成である。
X線検出ユニット30は、複数のX線検出器31を備えている。各X線検出器31は、試料Sの被測定箇所に対して、その周囲に配置され、試料Sから放射された蛍光X線を取り込んで検出する構成となっている。
また、X線検出ユニット30は、各X線検出器31をそれぞれ駆動するX線検出器駆動機構32を備えている。各X線検出器31は、それぞれX線検出器駆動機構32によって個別に駆動され、配置位置を変更できる構成となっている。
なお、本実施形態では、図示しない離間した位置に光学顕微鏡50による観察位置が設けてあり、その観察位置で光学顕微鏡50によりあらかじめ試料Sの被測定箇所を認識し、その認識した被測定箇所を、試料位置決め機構11により光学顕微鏡50の観察位置からX線の収束点まで移動する構成となっている。
かかる機能を備えた中央処理装置40は、複数のX線検出器31のうち、試料Sから回折してきた回折X線を検出したX線検出器31を、当該回折X線が入射しない位置へ移動させる「制御部」を構成する。
X線照射ユニット20は、連続X線を放出するX線源と、多波長ミラー21とを含む構成となっている。多波長ミラー21は、X線源から放出された連続X線を入射して、エネルギの大きさが異なる複数種類のX線を取り出す機能を有している。
多波長ミラー21は、複数種類の多層膜22を積層して形成してある。多層膜22は、複数種類の薄膜を積層した構成となっている。各多層膜22は、深さ方向に薄膜の膜厚、膜質及び薄膜の積層数を調整することで、エネルギの大きさが異なる複数種類のX線を回折できるように製作される。
かかる多波長ミラー21によって、X線源から放出される連続X線から所望の大きさのエネルギを有する複数種類のX線a,b,c,dを取り出すことが可能となる。
既述したように、半田バンプは、例えば、Sn(0.97)、Ag(0.03)の組成をもつ無鉛半田により形成される。これら半田バンプを構成する元素のうち、特にAgは含有量が少ないため、蛍光X線分析に際しては、このAgからの蛍光X線の放出量を多くするように、半田バンプに照射するX線のエネルギ特性を調整することが好ましい。
このように多層膜22の一つを調整することで、半田バンプを形成する元素のうち、含有量の少ないAgについてもX線の励起効率が上がり、Agから多くの蛍光X線が放出される。
同図から、半田バンプ(無鉛半田)を構成するSn(0.97)及びAg(0.03)のX線(K)の吸収端は、Snが29.2keVであり、Agが25.5keVであることがわかる。
なお、図5では、多波長ミラー21,21を、Kirkpatrick-Baez(KB)と呼ばれる直列方式で配置したが、互いに1辺が接するSide-by-side方式で配置することもできる。
図6は本実施形態に係る蛍光X線分析装置による蛍光X線分析の実施動作を示すフローチャートである。
具体的には、中央処理装置40は、当該X線検出器31を移動させるX線検出器駆動機構32の駆動コントローラ43に指令信号を出力する。この指令信号に従って、その駆動コントローラ43がX線検出器駆動機構32を駆動して、当該X線検出器31を回折X線が入射しない位置へ移動させる。
すなわち、中央処理装置40は、X線照射コントローラ42に指令信号を出力し、この指令信号に従って、X線照射ユニット20が半導体基板の被測定箇所にX線を照射する。そして、各X線検出器31が半導体基板の被測定箇所(半田バンプ)から放出された蛍光X線を検出し、その検出信号を中央処理装置40が入力して、蛍光X線分析が実行される。
その後、蛍光X線分析の分析結果を出力して(ステップS6)、測定動作が終了する。
次に、図7A~図9を参照して、本発明の第2実施形態に係る蛍光X線分析装置を説明する。
なお、先に説明した第1実施形態に係る蛍光X線分析装置と同一の構成要素又は相当する構成部分要素には、同一符号を付して、その構成要素の詳細な説明を省略することがある。
X線遮蔽扉36は、例えば、小形モータ等の駆動機構をもって開閉する構成とすることができる。
かかる機能を備えた中央処理装置40は、複数のX線検出器31のうち、試料から回折してきた回折X線を検出したX線検出器31に対し、X線遮蔽扉36を閉塞する「制御部」を構成する。
中央処理装置40は、キーボード等の操作部からオペレータが指定した、入射X線に対する半導体基板の面方位と配置方向を入力すると(ステップS11)、中央処理装置40が位置決めコントローラ41に指令信号を出力し、位置決めコントローラ41が試料位置決め機構11を駆動して、試料台10に配置した半導体基板の被測定箇所(半田バンプ)を、X線照射ユニット20から照射されるX線の収束点に位置決めする(ステップS12)。
具体的には、中央処理装置40は、当該X線遮蔽扉36を閉塞させる駆動機構の駆動コントローラ44に指令信号を出力する。この指令信号に従って、その駆動コントローラ44が駆動機構を駆動して、当該X線遮蔽扉36を閉塞する。
次に、図10及び図11を参照して、本発明の第3実施形態に係る蛍光X線分析装置を説明する。
なお、先に説明した第1及び第2実施形態に係る蛍光X線分析装置と同一の構成要素又は相当する構成部分要素には、同一符号を付して、その構成要素の詳細な説明を省略することがある。
中央処理装置40は、各X線検出器31から入力したX線の検出信号(X線のスペクトル)を比較して、回折X線の入射により異常値を示す検出信号を出力しているX線検出器31の有無をチェックする。そして、中央処理装置40は、複数のX線検出器31のうち、回折X線を検出したX線検出器31からの検出信号を除外する。
すなわち、本実施形態では、中央処理装置40が、回折X線を検出したX線検出器31からの検出信号を除外し、それ以外のX線検出器31から入力した検出信号に基づいて蛍光X線分析を行う「分析部」を構成する。
すなわち、中央処理装置40は、X線照射コントローラ42に指令信号を出力し、この指令信号に従って、X線照射ユニット20が半導体基板の被測定箇所にX線を照射する。そして、各X線検出器31が半導体基板の被測定箇所(半田バンプ)から放出された蛍光X線を検出し、その検出信号を中央処理装置40が入力して、蛍光X線分析が実行される。
その後、蛍光X線分析の分析結果を出力して(ステップS26)、測定動作が終了する。
次に、図12A~図14を参照して、本発明の第4実施形態に係る蛍光X線分析装置を説明する。
なお、先に説明した第1乃至第3実施形態に係る蛍光X線分析装置と同一の構成要素又は相当する構成部分要素には、同一符号を付して、その構成要素の詳細な説明を省略することがある。
X線照射ユニット20は、光学顕微鏡50の下方位置、すなわち光学顕微鏡50が観察できる位置に、照射X線の収束点を位置決めしてある。
実際には、後述するように、照射X線の収束点に粗く位置決めされた試料(半導体基板)Sの被測定箇所(半田バンプ)に焦点を合わせ、この被測定箇所を観察している。
すなわち、中央処理装置40は、X線照射コントローラ42に指令信号を出力し、この指令信号に従って、X線照射ユニット20が半導体基板の被測定箇所にX線を照射する。そして、各X線検出器31が半導体基板の被測定箇所(半田バンプ)から放出された蛍光X線を検出し、その検出信号を中央処理装置40が入力して、蛍光X線分析が実行される。
その後、蛍光X線分析の分析結果を出力して(ステップS38)、測定動作が終了する。
しかも本実施形態の構成によれば、光学顕微鏡50を利用してリアルタイムに半導体基板の被測定箇所を観察しながら、照射X線の収束点に対して高精度に半導体基板の被測定箇所を位置決めすることができる。
例えば、X線照射ユニット20は、多波長ミラー以外の光学機器を利用して、エネルギの大きさが異なる複数種類のX線を試料へ照射できるように構成してもよい。
