Abstract
Description
中でも樹脂基板のもの(樹脂製キャリア)は、軽量かつ安価で、金属基板のもの(金属製キャリア)のように保持孔にウェーハ周縁部を保護するためのインサートを必要としないためにシンプルな構造を有するという長所をもつ。
本発明者らは、親水性を純水に対する接触角の測定により定量化し、表裏面の接触角平均値が45°以上60°以下、かつ、オモテ面とウラ面の接触角の平均値の差が5°以内であれば、ウェーハの研磨レートを格段に向上させることができることを見出し、本発明を完成させた。
図1は本発明の両面研磨装置用キャリアを具備した本発明の両面研磨装置の一例の縦断面図であり、図2は平面視による両面研磨装置の内部構造図である。
また、上定盤4の上部には、上定盤4と下定盤3の間にスラリーを供給するスラリー供給機構6(ノズル7、および上定盤4の貫通孔8)が設けられている。スラリーとしては、コロイダルシリカを含有した無機アルカリ水溶液を用いることができる。
なお、本発明の両面研磨装置においては、このような遊星歯車方式のものに限定されず、揺動方式のものとすることも可能である。
このキャリア1は樹脂製であり、研磨布5と接触する表裏面の純水に対する接触角の平均値が45°以上60°以下であり、かつ、オモテ面とウラ面の接触角の平均値の差が5°以内のものである。この本発明のキャリア1は、上記のような接触角条件を満たしており、それによってウェーハWの研磨レートを従来の樹脂製キャリアを用いた場合に比べて格段に向上することができる。例えば10%以上、さらには25%以上、あるいはそれ以上に研磨レートを向上させることが可能である。比較する従来品によっては、本発明であれば研磨レートを倍以上にすることも可能である。その結果、両面研磨ウェーハの生産性を格段に高めることができる。
より好ましくはキャリア1は樹脂積層板からなり、その形成材料の一例として、親水性の繊維基材に樹脂を含浸させた複合材料(FRP)を用いることができる。繊維基材としては、ガラス・液晶ポリマー・セルロースなどが挙げられる。樹脂としては、エポキシ・アラミド・フェノールなどが挙げられる。これらの材料自体は従来からもよく用いられており、簡便に用意してキャリア1を製造することができる。ただし、本発明では表裏面の親水性が調整されている。これらの材料であれば、キャリアに適度な親水性の表面を形成しやすく、上記接触角条件を満たすのに有効である。
一方、接触角が66.8°のときの一例を図4示す(従来品)。このときのガラス繊維の表面露出率は36%である。
ガラス繊維の露出率が高い方が、接触角が低減している。
このように親水性の繊維基材の表面露出率によって接触角は異なりやすいので、その都度適切に表面露出率を調整することで、上記接触角条件を満たすキャリア1を得ることができる。
(実施例1-3)
接触角条件の異なる本発明の両面研磨装置用キャリアを用意した。そして、図1に示す両面研磨装置を用意し、上下定盤間に、両面研磨装置用キャリアの保持孔に保持した半導体シリコンウェーハを挟み込み、スラリーを供給しつつ両面研磨した。
そして、両面研磨後、ウェーハを洗浄し、研磨前後の厚み差から研磨レートを算出した。
・ウェーハは直径300mmのP型シリコン単結晶ウェーハを用いた。
・研磨装置は、不二越機械工業株式会社のDSP-20Bを用いた。
・研磨パッドは、ショアA硬度90の発泡ポリウレタンパッドを用いた。
・キャリアは、ガラス繊維にエポキシ樹脂を含浸したFRPを用いた。
・スラリーはシリカ砥粒含有、平均粒径35nm、砥粒濃度1.0wt%、pH10.5でKOHベースのものを用いた。
・加工時間はウェーハ厚みがキャリアと同一になるように設定した。
・各駆動部の回転速度は、上定盤:-13.4rpm、下定盤:35rpm、サンギア:25rpm、インターナルギア:7rpmに設定した。
・研磨パッドのドレッシングは、ダイヤ砥粒が電着されたドレスプレートを所定圧で純水を流しながら上下研磨パッドに摺接させることで行った。
・SC-1洗浄を条件NH4OH:H2O2:H2O=1:1:15で行った。
・キャリアの接触角測定には、協和界面科学株式会社のPCA-11を用いた。測定は片面毎に純水2.0μLの液滴を5箇所に滴下し、画像解析から接触角を求め、それらの平均値を片面の平均値とした。そして表裏を考慮する場合、オモテ面の平均値とウラ面の平均値で平均値(Ave)及び差(Dif)を算出した。
接触角条件が本発明の範囲外の従来の両面研磨装置用キャリアを用意した。
両面研磨装置用キャリア以外は実施例と同様の両面研磨装置を用意し、実施例と同様にして半導体シリコンウェーハの両面研磨を行い、洗浄し、研磨レートを算出した。
なお、実施例1-3は、純水に対する接触角の条件A:45°≦Ave≦60°、条件B:Dif≦5°の両方を満たしており、比較例1-4は、条件A、Bを共に満たしていないか、いずれか一方のみしか満たしていない。
例えば、基準の比較例2(研磨レート:1.00)に対して、実施例1では1.13とすることができ、10%以上向上することができた。また、実施例3では1.25であり、25%も向上することができた。それどころか、比較例4(0.50)と実施例3(1.25)を比べるとわかるように、倍以上の研磨レートを得ることができた。
例えば、比較例4(研磨レート:0.50)ではAve、Difの組み合わせが(42°、2°)であり、実施例3(1.25)は(45°、2°)である。このようにAveが45°以上であるかどうかで、研磨レートを飛躍的に向上させることができる。
なお、比較例4では、使用後の両面装置用キャリアを観察すると損耗があった。
