Abstract
試料表面の付着物を均一に除去して処理の歩留まりを向上させたプラズマ処理装置を提供することにある。
【解決手段】
処理室内に配置された試料台上に載せられたウエハの上面に配置された複数の膜構造を前記試料台内の電極に高周波電力を供給しつつ、前記処理室内で形成したプラズマを用いてエッチング処理するプラズマ処理装置であって、前記試料台の前記試料が載せられる面の外周側の前記電極の上方に配置されたリング状の電極及びこのリング状の電極の上方に配置されて前記プラズマと面する誘電体からなる外周リングと、前記リング状の電極に前記膜構造の膜の種類に応じて異なる値の電力を供給する電源とを備えたプラズマ処理装置。

Description
27,27′内のウエハ配置の姿勢に合わせてその位置合わせを行う。
27,27′はそれぞれ同等の機能を有しており、いずれか一方がウエハを大気圧から真空へ(ロード)或いは真空から大気圧へ(アンロード)の圧力変化のいずれかのみを実施するものではないが、求められる仕様により一方を何れかに限定して使用しても良い。
26,26′と真空容器24,24′との間を連結して支持する複数の支持柱を有して、処理ユニット14,14′を固定し保持している。
50に供給される電界を発生する電波源及び磁場を発生するための手段と処理室50内側を排気して減圧する真空ポンプを有する真空排気装置53が配置されている。処理室50内部において試料台100の試料載置面の上方には、これに対向して処理室50の天井面を構成するように試料110の径よりも大きな径を有した略円形の板であるシャワープレート60が配置されている。シャワープレート60は、試料台100またはこれに載せられる試料110の中心とほぼ同軸の中心の周囲に配置された複数の貫通孔を有し、この貫通孔を通して上記ガス供給ユニット17から共有された処理用ガスが処理室50の天井部に供給される。
100内の電極に高周波電極61から供給された高周波電力により試料110上方に所定のバイアス電位が形成され、この電位とプラズマの電位差に応じて、プラズマ中の荷電粒子が試料表面に誘引されて異方性を有するエッチング処理が促進される。このようなエッチング処理に伴って処理室50内に生成物が生起する。
100及び開口54と真空排気装置53の真空ポンプとが略同心に配置されている。このような構成により、処理の軸周り、試料110の周方向について処理の均一性が向上され処理の歩留まりが向上される。なお、図示していないが、本実施例では、上記処理ユニット13を含む真空処理装置10の各部の動作を調節するため、これら各部の動作を検出するセンサからの信号を通信手段を介し受信して、この受信した信号から各部の状態を検出した結果を基づきこれら各部の動作を指令する信号を通信手段を介して発進してこれらの動作を調節する制御装置を備えている。
111との間の空間に試料110の裏面側から外周側上方へガスを供給する手段を配置している。すなわち、本実施例では、試料台100の凸起部の上部外周側の凹み部に基材を貫通して配置されたガス供給絶縁ボス116を備え、凹み部上表面の複数の箇所に凸起部を囲むように略等間隔に配置された開口から特定のガスを導入して処理室50から試料
110の外周縁部の裏面とフォーカスリング111の段差部111′表面との間の空間に進入してきた付着性の物質を再度処理室50側に排出しようとする構成を備えている。
(605)た後、静電吸着用の直流電力を停止し(606)て試料110の吸着を解除する。その後、処理済の試料110を試料台100上方に持ち上げて遊離させて処理室50外に搬出する。
111へ給電する(下方の給電リング112へ高周波電力を供給する)ことで、供給された不活性ガスのプラズマ放電を試料110の外周縁近傍に生起させる。このプラズマ中の荷電粒子,反応性粒子と試料110表面との相互作用により試料110の周縁部裏面表面への付着物を除去、あるいは付着を抑制する。
50内に導入して、試料110表面の膜の加工した形状を適正に調節する場合がある。例えば、エッチングにより溝形状を形成する場合に有機成分を有するガス(CxHyや
CxHyOz等)を導入して溝の側壁の表面のエッチングを抑制して深さ方向へのエッチングを相対的に大きくすることで、深い(アスペクト比の大きな)溝で溝の幅が深さ方向により均一である溝形状を形成することが行われる。
110表面の付着物の分布が所期のものからずれてしまい処理対象の膜の加工結果が所望の形状からずれてしまうという問題が生起する虞がある。このため、本実施例では、試料110表面のバイアス電位とフォーカスリング111表面のバイアス電位との間の差が少なくなるようにして、試料110外周縁部近傍でのプラズマ形成を抑制する(603)。
Si層705の上方にSiO2 膜704及びその上方のPolySi膜703を備え、さらにその上方にハードマスクとしてのSiN膜702及びこのSiN膜702の加工形状を所望に調節するためのマスクとしてのレジスト膜701を備えている。レジスト膜701としては、フォトレジストやArFレジスト等の何れでも良い。
PolySi膜またはW−PolySi膜等の膜層707及び自然酸化膜706を備えている。この場合、エッチング処理の初期でハードマスクとなる自然酸化膜等の処理では、付着物ガスを添加しないか少なく添加してエッチングメインのガスによりエッチングを進める。
801表面の電子放出能力を高めてプラズマ発生を容易にする。
