By preparing such a data table, the rotation period P (rotational speed S) can be calculated more easily.
- the actual staying time in the processing chamber requires time to accelerate to the predetermined rotational speed S (acceleration time) and time to decelerate (deceleration time). It becomes.
- the film thickness distribution at the time of acceleration is biased, but the film thickness distribution at the time of deceleration compensates for it.
- sputter film formation can be performed even during acceleration / deceleration, so that the residence time in the processing chamber can be shortened without deteriorating the film thickness distribution.

Abstract
Description
本願は、2010年6月30日に出願された特願2010-149321号について優先権を主張し、その内容をここに援用する。
また、近年のスパッタリング装置においては、スパッタリングの性能の向上のために、スパッタリング時における投入パワーの増加が図られている。これにより、より短時間での成膜が可能となり、スループットの向上を実現することができる。
本発明の成膜装置は、スパッタ成膜により被膜を形成すべき基板を内部に配置するチャンバと、前記チャンバ内に配置された、前記被膜の形成材料を含むターゲットと、前記チャンバの内部に配置された基板支持台と、前記基板支持台を回転させる駆動手段と、前記ターゲットが装着され前記基板支持台の上の基板に対してスパッタ粒子を斜め方向から入射させるスパッタリングカソードと、所望の膜厚の被膜の形成に要するスパッタ成膜時間であって、前記支持台が所定の回転周期で回転するスパッタ成膜時間が、前記基板支持台の回転周期の整数倍となるように回転周期を定め、前記駆動手段の制御を行う制御装置とを備えることを特徴とする。
また、基板支持台の回転速度が低下することになるため、消費電力が抑えられ、装置の長寿命化を実現することができる。
また、基板支持台の回転周期が所定の回転周期となるまでの加速中、及び、成膜終了後の減速中においてもスパッタ成膜を行うことによって、さらに成膜時間を短縮することができる。
図1は、本実施形態に係る成膜装置1の概略断面図である。本実施形態において、成膜装置1は、マグネトロンスパッタ装置として構成されている。
成膜装置1は、内部を気密封止しうるチャンバ2と、この真空チャンバ2の内部に配置された基板支持台3と、この基板支持台3を回転軸4を軸心として回転させる駆動手段7と、真空チャンバ2の内部に配置された複数(本実施の形態においては3組)のスパッタリングカソード5A,5B,5C等を備えている。
さらに、制御装置8は、計算されたスパッタ時間Tに応じて、回転周期P(秒)を決定する機能を有する。ここで、回転周期Pとは、基板支持台3が1回転するのに要する時間(秒)であり、基板支持台3の回転速度をSrpm(回転/分)とすると、P=60/Sで計算される値である。
T=n×P ・・・(1)
すなわち、以下の数式(2)で、回転周期Pが計算される。
P=(1/n)×T ・・・(2)
このような方法で算出された回転周期Pとなるような回転速度Sで基板支持台3を回転させる制御を行うことによって、基板支持台3(基板W)は、スパッタ成膜時間Tの間に正確にn回転する。
しかしながら、回転周期Pが長すぎる場合、すなわち回転速度Sが遅くなりすぎることによって、膜厚均一度及び駆動モータの振動等の問題が生じるため、最長回転周期Pmax(最低回転速度)を設定しておくことが好ましい。計算された回転周期Pが、最長回転周期Pmaxに満たない場合は、上記計算式のnの値を順次大きくすることによって最長回転周期Pmaxを超えないようにする再計算を行う。
例えば、スパッタ成膜時間Tが60秒以下であると予測できる場合は、スパッタ成膜時間が1秒以上30秒未満の場合は、スパッタ成膜時間Tで基板支持台3を1回転させるように制御するように定める。また、スパッタ成膜時間Tが30秒以上60秒以下の場合は、スパッタ成膜時間Tで、基板支持台3を2回転させるように制御するように定める。このようなデータテーブルを用意することで、より容易に回転周期P(回転速度S)を計算することができる。
更なる処理室滞在時間の短縮のため、以下のような方法で加速時間及び減速時間においてもスパッタ成膜を行うことが好ましい。つまり、加速時間における加速度を一定にするとともに、減速時間における加速度を一定にし、かつ、加速時間の加速度と減速時間の加速度の絶対値を等しくするように加速減速を行わせることによって、加速時間及び減速時間においてもスパッタ成膜を行う。
実施例1では、図1、2に示す成膜装置1を用い、Cu膜を成膜した。基板Wとして、φ300mmのSiウエハを用いた。また、ターゲットとして、Cuの組成比が99%で、スパッタ面の径がφ125mmに作製したものを用いた。成膜するCu膜の膜厚は1.5μmとした。
回転周期P(回転速度)を制御しないこと以外は、実施例1と同様の方法で成膜を行った。回転周期Pは1秒(回転速度60rpm)とした。
実施例2では、図1に示す成膜装置1を用い、Cu膜を成膜した。基板Wとして、φ300mmのSiウエハを用いた。また、ターゲットとして、Cuの組成比が99%で、スパッタ面の径がφ125mmに作製したものを用いた。成膜するCu膜の膜厚は180μmとした。つまり、実施例1と比較して、Cu膜の膜厚を厚くした。
1≦T≦10(秒) :n=1(回転)
10<T≦20(秒) :n=2(回転)
20<T≦60(秒) :n=3(回転)
60<T≦120(秒) :n=4(回転)
120<T≦300(秒):n=5(回転)
上記したデータテーブルより、スパッタ成膜時間Tの間に回転する基板支持台3の回転回数は4となる。前記した式、P=(1/n)×Tより、回転周期Pは((1/4)×120=)30秒となる。
基板支持台3の加速中、及び基板支持台3の減速中においてもスパッタ成膜を行うこと以外は、実施例2と同様の方法で成膜を行った。
基板支持台3を2rpmまで加速するのに必要な時間は2秒であるが、加速時間、及び減速時間は、少なくとも2rpmにおける回転周期P=30秒の整数倍とする必要があるため、加速時間及び減速時間はそれぞれ30秒とした。
また、加速中の加速度と減速中の加速度は一定であり、かつ、加速中の加速度と減速中の加速度の絶対値が等しくなるように、加速、減速を行った。
従来の方法で、成膜を行った。成膜時間は、実施例と同様に120秒である。一方、ステージ回転速度は、60rpm(回転周期1秒)とした。また、60rpmまで加速するのに必要な時間は30秒であり、60rpmから停止させるのに必要な時間も30秒である。
