Description

本考案は、電極間に生成されたプラズマにより処理を行うプラズマ処理装置に関する。   The present invention relates to a plasma processing apparatus that performs processing using plasma generated between electrodes.

エクスターナル型電極を有するプラズマ処理装置は、処理室内で基板を載置する接地された接地電極、及び処理室の外部に露出した裏面に高周波電源が接続された高周波電極を備える。接地電極及び高周波電極それぞれの表面は対向配置される。通常、接地電極は、高周波電極よりも大きな表面積を有する。高周波電極の表面には、着脱可能な電極板が取り付けられる。   A plasma processing apparatus having an external electrode includes a grounded ground electrode on which a substrate is placed in a processing chamber, and a high-frequency electrode having a high-frequency power source connected to the back surface exposed to the outside of the processing chamber. The surfaces of the ground electrode and the high-frequency electrode are opposed to each other. Usually, the ground electrode has a larger surface area than the high-frequency electrode. A removable electrode plate is attached to the surface of the high-frequency electrode.

高周波電力が高周波電極の裏面から供給され、接地電極及び高周波電極の間にプラズマが生成される。生成されたプラズマにより、基板がプラズマ処理される。   High frequency power is supplied from the back surface of the high frequency electrode, and plasma is generated between the ground electrode and the high frequency electrode. The substrate is subjected to plasma treatment by the generated plasma.

高周波電極表面への電極板の取り付けに通常の六角ボルトを使用すると、電極板着脱の利便性は高い。しかし、電極板表面から突出した六角ボルトの頭部により、接地電極及び高周波電極間の距離が不均一となる。そのため、六角ボルトの頭部への電界集中に起因して、プラズマ処理の均一性が劣化する。   When a normal hexagon bolt is used to attach the electrode plate to the surface of the high frequency electrode, the convenience of attaching / detaching the electrode plate is high. However, the distance between the ground electrode and the high-frequency electrode becomes non-uniform due to the head of the hexagon bolt that protrudes from the surface of the electrode plate. For this reason, the uniformity of the plasma processing is deteriorated due to the electric field concentration on the head of the hexagon bolt.

また、高周波電極表面への電極板の取り付けに皿ボルトを使用すると、プラズマ処理の均一性の劣化を抑制することができる。しかし、皿ボルトの締め付けは、頭部頂面に設けられたすりわりや十字溝等の締め付け溝にドライバ等の締め付け工具を差し込んで行われる。そのため、電極板着脱に際して、皿ボルトにトルクをかけにくく、締め付けが不十分となりやすい。また、締め付けにより、締め付け溝がつぶれることもある。このように、皿ボルトを用いて電極板を高周波電極に取り付けると、電極板着脱時の利便性が悪い。更に、電極板に設ける皿ボルト挿入用の貫通孔には、十分な遊びを持たせることができないため、プラズマ処理時の電極板の熱膨張によるボルト緩みが発生するという問題も生じる。   In addition, if a countersunk bolt is used to attach the electrode plate to the surface of the high-frequency electrode, it is possible to suppress deterioration in uniformity of plasma processing. However, the countersunk bolt is tightened by inserting a tightening tool such as a screwdriver into a tightening groove such as a slot or a cross groove provided on the top surface of the head. Therefore, when attaching and detaching the electrode plate, it is difficult to apply torque to the countersunk bolt, and tightening tends to be insufficient. Further, the tightening groove may be crushed by tightening. Thus, if an electrode plate is attached to a high frequency electrode using a countersunk bolt, the convenience at the time of electrode plate attachment / detachment will be bad. Furthermore, since the through-hole for inserting the countersunk bolt provided in the electrode plate cannot have sufficient play, there arises a problem that the bolt loosens due to thermal expansion of the electrode plate during plasma processing.

本考案の目的は、プラズマ処理の均一性の劣化を抑制することが可能なプラズマ処理装置を提供することにある。   An object of the present invention is to provide a plasma processing apparatus capable of suppressing deterioration in uniformity of plasma processing.

本考案の態様によれば、(イ)基板にプラズマ処理を行う処理室と、(ロ)処理室の内部に配置され、基板を上面に載置する接地電極と、(ハ)プラズマ空間を挟んで接地電極と対向する電極板と、(ニ)電極板をプラズマ空間側の第1主面に電気的に接続し、第1主面の反対側の第2主面を高周波電源に接続した高周波電極と、(ホ)頭部の厚さが1mm〜2mmの範囲であり、頭部を接地電極に対向させ、電極板を高周波電極に固定する低頭六角ボルトとを備えるプラズマ処理装置が提供される。   According to the aspects of the present invention, (b) a processing chamber for performing plasma processing on a substrate, (b) a ground electrode disposed inside the processing chamber and mounting the substrate on the upper surface, and (c) sandwiching the plasma space The electrode plate facing the ground electrode and (d) the electrode plate is electrically connected to the first main surface on the plasma space side, and the second main surface opposite to the first main surface is connected to the high frequency power source.

However, it should be noted that the drawings are schematic, and the relationship between the thickness and the planar dimensions, the ratio of the thickness of each layer, and the like are different from the actual ones. Therefore, specific thicknesses and dimensions should be determined in consideration of the following description.

又、以下に示す本考案の実施の形態は、本考案の技術的思想を具体化するための装置や方法を例示するものであって、本考案の技術的思想は、構成部品の材質、形状、構造、配置等を下記のものに特定するものでない。本考案の技術的思想は、特許請求の範囲に記載された技術的範囲内において、種々の変更を加えることができる。   Further, the embodiments of the present invention shown below exemplify apparatuses and methods for embodying the technical idea of the present invention, and the technical idea of the present invention is based on the material and shape of components. The structure, arrangement, etc. are not specified below. The technical idea of the present invention can be variously modified within the technical scope described in the claims.

本考案の実施の形態に係るプラズマ処理装置、例えばプラズマ成膜装置は、図1に示すように、処理室10、接地電極12、高周波電極14を備える。処理室10は、プラズマ反応により基板20にプラズマ処理を行う真空チャンバである。プラズマ処理の対象となる基板20は接地電極12上に載置される。なお、図1では基板20は接地電極12表面に直接載置されているが、接地電極12上に設置した導電体あるいは絶縁体からなるプレート上に基板20を載置してもよい。   As shown in FIG. 1, a plasma processing apparatus according to an embodiment of the present invention, for example, a plasma film forming apparatus, includes a processing chamber 10, a ground electrode 12, and a high-frequency electrode 14. The processing chamber 10 is a vacuum chamber that performs plasma processing on the substrate 20 by plasma reaction. The substrate 20 to be subjected to plasma processing is placed on the ground electrode 12. In FIG. 1, the substrate 20 is directly placed on the surface of the ground electrode 12, but the substrate 20 may be placed on a plate made of a conductor or an insulator placed on the ground electrode 12.

接地電極12は、接地される。高周波電極14は、プラズマを生成するプラズマ空間26を挟んで接地電極12の上面と対向する。高周波電極14は、処理室10の筐体にスペーサ22を介して取り付けられる。   The ground electrode 12 is grounded. The high-frequency electrode 14 faces the upper surface of the ground electrode 12 with a plasma space 26 for generating plasma interposed therebetween. The high frequency electrode 14 is attached to the housing of the processing chamber 10 via a spacer 22.

高周波電極14は、プラズマ空間26側の第1主面と、第1主面の反対側で高周波電源24に接続される第2主面とを有する。高周波電極14の第1主面には、表面がプラズマ空間26に面する電極板16が取り付けられる。高周波電極14の第2主面は、処理室10の外部に露出し、高周波電源24に接続される。   The high-frequency electrode 14 has a first main surface on the plasma space 26 side and a second main surface connected to the high-frequency power source 24 on the opposite side of the first main surface. An electrode plate 16 whose surface faces the plasma space 26 is attached to the first main surface of the high-frequency electrode 14. The second main surface of the high frequency electrode 14 is exposed to the outside of the processing chamber 10 and connected to the high frequency power source 24.

電極板16は、高周波電極14の第1主面に電気的に接続される。低頭六角ボルト18は、頭部を接地電極12に対向させ、高周波電極14の第1主面に電極板16を固定する。   The electrode plate 16 is electrically connected to the first main surface of the high-frequency electrode 14. The low-head hexagon bolt 18 has the head opposed to the ground electrode 12 and fixes the electrode plate 16 to the first main surface of the high-frequency electrode 14.

高周波電極14は、図1に示したように、処理室10の筐体と共に圧力隔壁として作用する。したがって、高周波電極14は処理室から取り外すことは困難である。そのため、プラズマ処理後のメンテナンスのため、電極板16は、高周波電極14から機械的に着脱可能である。なお、低頭六角ボルト18は、図1においては1本示されているが、低頭六角ボルト18の数は限定されず、2以上の複数の本数であってもよい。   As shown in FIG. 1, the high-frequency electrode 14 functions as a pressure partition wall together with the housing of the processing chamber 10. Therefore, it is difficult to remove the high frequency electrode 14 from the processing chamber. Therefore, the electrode plate 16 can be mechanically detached from the high frequency electrode 14 for maintenance after the plasma treatment. Although one low-head hexagon bolt 18 is shown in FIG. 1, the number of low-head hexagon bolts 18 is not limited and may be a plurality of two or more.

図1に示した電極板16と接地電極12との間隔Deは、プラズマ空間26の厚さに対応し、均一なプラズマを生成するためには均一であることが望ましい。しかし、低頭六角ボルト18の頭部は、プラズマ空間26に突出し、接地電極12との間隔Dbが小さくなる。そのため、低頭六角ボルト18の頭部への電界集中が起こり、プラズマが不均一になる。その結果、プラズマ処理が不均一になってしまう。   The distance De between the electrode plate 16 and the ground electrode 12 shown in FIG. 1 corresponds to the thickness of the plasma space 26 and is desirably uniform in order to generate uniform plasma. However, the head of the low-head hex bolt 18 protrudes into the plasma space 26 and the distance Db from the ground electrode 12 is reduced. Therefore, the electric field concentration on the head of the low-head hex bolt 18 occurs, and the plasma becomes non-uniform. As a result, the plasma processing becomes non-uniform.

例えば、図1に示した高周波電極14及び電極板16の寸法を約500mm、電極板16と接地電極12との間隔Deを約40mmとする。低頭六角ボルト18として、M5の低頭ボルトを用いる。低頭六角ボルト18は、図2及び図3に示すように、電極板16に設けられた貫通孔17を通して高周波電極14に設けられたメネジ孔19に締めこまれる。なお、図4に示すように、低頭六角ボルト18aとして段付きボルトを用いてもよい。   For example, the dimensions of the high-frequency electrode 14 and the electrode plate 16 shown in FIG. 1 are about 500 mm, and the distance De between the electrode plate 16 and the ground electrode 12 is about 40 mm. As the low-head hex bolt 18, an M5 low-head bolt is used. As shown in FIGS. 2 and 3, the low-head hexagon bolt 18 is fastened to a female screw hole 19 provided in the high-frequency electrode 14 through a through-hole 17 provided in the electrode plate 16. As shown in FIG. 4, a stepped bolt may be used as the low-head hex bolt 18a.

M5の低頭六角ボルト18は、ボルト頭部の厚さkが約1.5mmである。したがって、低頭六角ボルト18の頭部と接地電極12との間隔Dbは、電極板16と接地電極12との間隔Deに対して約3.8%の変化量である。一方、通常の六角ボルトの頭部の厚さは約3.5mmであり、間隔Dbの間隔Deに対する変化量は、約8.8%である。このように、実施の形態では、間隔Dbの変化が小さく、プラズマ処理の均一性の劣化を抑制することが可能となる。また、低頭六角ボルト18は、スパナ等の締め付け工具により締め付け、取り外しができ、利便性がよい。   The M5 low head hex bolt 18 has a bolt head thickness k of about 1.5 mm. Therefore, the distance Db between the head of the low-head hexagon bolt 18 and the ground electrode 12 is a change amount of about 3.8% with respect to the distance De between the electrode plate 16 and the ground electrode 12. On the other hand, the thickness of the head of a normal hexagon bolt is about 3.5 mm, and the amount of change of the distance Db with respect to the distance De is about 8.8%. As described above, in the embodiment, the change in the interval Db is small, and it is possible to suppress the deterioration of the uniformity of the plasma processing. Further, the low-head hexagon bolt 18 can be tightened and removed with a tightening tool such as a spanner, and is convenient.

なお、厚さkが1mmより小さいと、低頭六角ボルト18の強度が低減し、また、締めこみ作業の利便性も低下する。厚さkが2mmを超えると、プラズマ処理の均一性の劣化が顕著となる。したがって、低頭六角ボルト18の頭部の厚さkは、1mm〜2mmの範囲が望ましい。   If the thickness k is smaller than 1 mm, the strength of the low-head hex bolt 18 is reduced, and the convenience of the tightening operation is also lowered. When the thickness k exceeds 2 mm, the deterioration of the uniformity of the plasma processing becomes significant. Therefore, the thickness k of the head of the low-head hex bolt 18 is desirably in the range of 1 mm to 2 mm.

また、高周波電極14及び電極板16に用いるステンレス鋼を、それぞれSUS304及びSUS430とする。SUS304及びSUS430の熱膨張係数は、それぞれ16×10-6-1及び11×10-6-1である。プラズマ処理時の仕様温度を400℃とすると、熱膨張による高周波電極14及び電極板16の延びの差は、約1mmとなる。 The stainless steel used for the high-frequency electrode 14 and the electrode plate 16 is SUS304 and SUS430, respectively. The thermal expansion coefficients of SUS304 and SUS430 are 16 × 10 −6 K −1 and 11 × 10 −6 K −1 , respectively. If the specification temperature during plasma processing is 400 ° C., the difference in the extension of the high-frequency electrode 14 and the electrode plate 16 due to thermal expansion is about 1 mm.

M5の低頭六角ボルト18は、呼び径daが約5mm、ボルト頭部の六角対辺の二面幅Sが約8mmである。そのため、電極板16に設ける貫通孔17の直径dtを約6.5mmと大きくすることができる。その結果、高周波電極14及び電極板16間のプラズマ処理時の熱膨張歪を約1.5mm許容でき、熱膨張による低頭六角ボルト18の緩みを防止することができる。   The M5 low-head hexagon bolt 18 has a nominal diameter da of about 5 mm and a width across flats S of the bolt head of about 6 mm. Therefore, the diameter dt of the through hole 17 provided in the electrode plate 16 can be increased to about 6.5 mm. As a result, the thermal expansion strain during plasma processing between the high-frequency electrode 14 and the electrode plate 16 can be allowed to be about 1.5 mm, and the low-head hexagon bolt 18 can be prevented from loosening due to thermal expansion.

上記のように、M5の低頭六角ボルト18を用いて説明したが、低頭六角ボルト18のネジ径は限定されない。低頭六角ボルト18として、電極板16着脱時の利便性を考慮して、M4〜M12のネジ径が望ましい。   As described above, the M5 low-head hex bolt 18 has been described, but the screw diameter of the low-head hex bolt 18 is not limited. As the low-head hex bolt 18, a screw diameter of M4 to M12 is desirable in consideration of convenience when the electrode plate 16 is attached and detached.
