[發明所欲解決之課題][Problem to be solved by the invention]

於專利文獻1所揭示的電漿處理裝置中，於處理室的外部排列配置有呈直線狀的多個天線。由於越接近天線電漿越強，因此於所述電漿處理裝置中，存在無法對配置於處理室的被處理物均勻地進行電漿處理的問題。In the plasma processing apparatus disclosed in Patent Document 1, a plurality of linear antennas are arranged in an array outside the processing chamber. Since the plasma is stronger as it is closer to the antenna, there is a problem that the plasma processing apparatus cannot perform plasma processing uniformly on the object to be processed arranged in the processing chamber.

〔實施方式1〕 ＜電漿處理裝置1的結構＞ 圖1是表示本發明的實施方式1的電漿處理裝置1的剖面結構的剖面圖。於圖1中，將天線6移動的方向設為X軸方向，將自真空容器2朝向磁場導入窗3的方向設為Z軸方向，將與X軸方向及Z軸方向此兩個方向正交的方向設為Y軸方向。X軸方向、Y軸方向及Z軸方向是相互正交的方向。圖1的符號101及符號102表示天線6藉由機構部7於X軸方向上移動的情形。再者，於圖1中，關於天線6及機構部7，並非剖面圖而是自Y軸方向觀察的圖。 [Embodiment 1] <Structure of plasma processing device 1> FIG. 1 is a cross-sectional view showing the cross-sectional structure of a plasma processing apparatus 1 according to Embodiment 1 of the present invention. In FIG. 1 , let the direction in which the antenna 6 moves be the X-axis direction, let the direction from the vacuum container 2 toward the magnetic field introduction window 3 be the Z-axis direction, and let the two directions orthogonal to the The direction is set to the Y-axis direction. The X-axis direction, the Y-axis direction, and the Z-axis direction are mutually orthogonal directions. Symbols 101 and 102 in FIG. 1 represent a state in which the antenna 6 moves in the X-axis direction by the mechanism unit 7 . In addition, in FIG. 1 , the antenna 6 and the mechanism part 7 are not cross-sectional views but views viewed from the Y-axis direction.

如圖1所示，電漿處理裝置1是使用電感耦合型的電漿P1對基板等被處理物W1實施電漿處理的裝置。此處，基板是例如液晶顯示器或有機電致發光（electroluminescence，EL）顯示器等平板顯示器（flat panel display，FPD）用的基板、或可撓性顯示器用的可撓性基板等。另外，被處理物W1可為用於各種用途的半導體基板。進而，被處理物W1例如如工具等般並不限於基板狀的形態。對被處理物W1實施的處理例如是利用電漿化學氣相沈積（Chemical Vapor Deposition，CVD）法或者濺鍍法的膜形成、利用電漿的蝕刻、灰化、被覆膜除去等。As shown in FIG. 1 , the plasma processing device 1 is a device that performs plasma processing on a target object W1 such as a substrate using an inductively coupled plasma P1. Here, the substrate is, for example, a substrate for a flat panel display (FPD) such as a liquid crystal display or an organic electroluminescence (EL) display, a flexible substrate for a flexible display, or the like. In addition, the object W1 to be processed may be a semiconductor substrate used for various purposes. Furthermore, the object W1 to be processed, such as a tool, is not limited to a substrate-shaped form. The processing performed on the object W1 is, for example, film formation using a plasma chemical vapor deposition (CVD) method or a sputtering method, etching using plasma, ashing, and coating film removal.

電漿處理裝置1包括：真空容器2、磁場導入窗3、天線6、機構部7、高頻電源8以及保持部9。關於高頻電源8，示於圖2。於真空容器2的內部形成有被真空排氣且被導入氣體的處理室21。於處理室21內收容保持部9，保持部9是對被處理物W1進行保持的平台。真空容器2例如是金屬製的容器。於真空容器2的壁面22形成有於厚度方向貫通的開口部23。真空容器2電性接地。The plasma processing apparatus 1 includes a vacuum container 2 , a magnetic field introduction window 3 , an antenna 6 , a mechanism part 7 , a high-frequency power supply 8 and a holding part 9 . The high-frequency power supply 8 is shown in FIG. 2 . A processing chamber 21 in which vacuum is exhausted and gas is introduced is formed inside the vacuum container 2 . The holding part 9 is housed in the processing chamber 21 and is a platform that holds the object W1 to be processed. The vacuum container 2 is, for example, a metal container. An opening 23 penetrating through the wall surface 22 of the vacuum container 2 in the thickness direction is formed. The vacuum container 2 is electrically grounded.

導入至處理室21的氣體只要與對收容於處理室21的被處理物W1實施的處理內容對應即可。例如，於藉由電漿CVD法對被處理物W1進行膜形成的情況下，氣體是原料氣體或用H 2等稀釋氣體將其稀釋後的氣體。若進一步列舉具體例，則於原料氣體為SiH 4的情況下，可於被處理物W1上形成Si膜，於原料氣體為SiH 4+NH 3的情況下，可於被處理物W1上形成SiN膜，於原料氣體為SiH 4+O 2的情況下，可於被處理物W1上形成SiO 2膜，於原料氣體為SiF 4+N 2的情況下，可於被處理物W1上形成SiN：F膜（氟化矽氮化膜）。 The gas introduced into the processing chamber 21 only needs to correspond to the processing content to be performed on the object W1 accommodated in the processing chamber 21 . For example, when forming a film on the object W1 to be processed by the plasma CVD method, the gas is a raw material gas or a gas diluted with a diluting gas such as H 2 . If further specific examples are given, when the source gas is SiH 4 , a Si film can be formed on the object W1 to be processed, and when the source gas is SiH 4 +NH 3 , SiN can be formed on the object W1 to be processed. Film, when the raw material gas is SiH 4 +O 2 , a SiO 2 film can be formed on the object to be processed W1, and when the raw material gas is SiF 4 +N 2 , an SiN film can be formed on the object to be processed W1: F film (fluorosilicone nitride film).

磁場導入窗3具有金屬板4及電介質板5。磁場導入窗3為了於處理室21產生電漿P1，將自天線6產生的高頻磁場導入至處理室21。朝向Z軸方向依次配置金屬板4及電介質板5。The magnetic field introduction window 3 has a metal plate 4 and a dielectric plate 5 . The magnetic field introduction window 3 introduces the high-frequency magnetic field generated from the antenna 6 into the processing chamber 21 in order to generate plasma P1 in the processing chamber 21 . The metal plate 4 and the dielectric plate 5 are arranged in order toward the Z-axis direction.

圖2是僅示出圖1所示的電漿處理裝置1的說明上必要的構件的立體圖。再者，於圖2中，省略了真空容器2、電介質板5及框體B1等的圖示。圖2的符號201及符號202表示天線6藉由機構部7於X軸方向上移動的情形。FIG. 2 is a perspective view showing only components necessary for explanation of the plasma processing apparatus 1 shown in FIG. 1 . In addition, in FIG. 2 , illustration of the vacuum container 2 , the dielectric plate 5 , the frame B1 , etc. is omitted. Symbols 201 and 202 in FIG. 2 indicate that the antenna 6 moves in the X-axis direction by the mechanism part 7 .

金屬板4以堵塞開口部23的方式設置於真空容器2的壁面22。於金屬板4形成有在Z軸方向上貫通金屬板4的多個狹縫41。多個狹縫41分別於X軸方向（第一方向）上延伸，並且多個狹縫41以沿著Y軸方向（第二方向）排列的方式配置。金屬板4以與被處理物W1的表面實質上平行的方式配置。The metal plate 4 is provided on the wall surface 22 of the vacuum container 2 so as to block the opening 23 . The metal plate 4 is formed with a plurality of slits 41 penetrating the metal plate 4 in the Z-axis direction. The plurality of slits 41 each extend in the X-axis direction (first direction), and the plurality of slits 41 are arranged along the Y-axis direction (second direction). The metal plate 4 is arranged substantially parallel to the surface of the object W1.

電介質板5自真空容器2的外部側與金屬板4相接地設置，並且與金屬板4重疊。另外，電介質板5以自真空容器2的外部側堵塞多個狹縫41的方式設置於金屬板4的天線6側的表面。電介質板5將真空容器2的內部與外部隔離。藉此，可藉由電介質板5維持處理室21的真空狀態。更具體而言，藉由堵塞開口部23的金屬板4以及堵塞多個狹縫41的電介質板5來維持處理室21的真空狀態。The dielectric plate 5 is provided in contact with the metal plate 4 from the outside side of the vacuum container 2 and overlaps the metal plate 4 . In addition, the dielectric plate 5 is provided on the surface of the metal plate 4 on the antenna 6 side so as to block the plurality of slits 41 from the outside of the vacuum container 2 . The dielectric plate 5 isolates the inside of the vacuum container 2 from the outside. Thereby, the vacuum state of the processing chamber 21 can be maintained by the dielectric plate 5 . More specifically, the vacuum state of the processing chamber 21 is maintained by the metal plate 4 that closes the opening 23 and the dielectric plate 5 that closes the plurality of slits 41 .

電介質板5的整體由電介質物質構成，電介質板5呈平板狀。構成電介質板5的材料可為氧化鋁、碳化矽或氮化矽等陶瓷、石英玻璃、無鹼玻璃等無機材料、聚醯亞胺或鐵氟隆（Teflon）（註冊商標）等氟樹脂之類的樹脂材料。於構成電介質板5的材料中包含鐵氟隆的情況下，電介質板5局部地具有透過性的區域，亦可為於鐵氟隆片上接著有玻璃片的結構。The entire dielectric plate 5 is made of a dielectric material, and the dielectric plate 5 has a flat plate shape. The material constituting the dielectric plate 5 may be alumina, ceramics such as silicon carbide or silicon nitride, inorganic materials such as quartz glass, alkali-free glass, or fluororesins such as polyimide or Teflon (registered trademark). resin material. When the material constituting the dielectric plate 5 contains Teflon, the dielectric plate 5 may have a partially transparent area, or may have a structure in which a glass sheet is bonded to the Teflon sheet.

天線6呈直線狀，設置於真空容器2的外部，且以與磁場導入窗3相向並且於Y軸方向上延伸的方式被機構部7支持。藉由天線6設置於真空容器2的外部，與天線6設置於真空容器2的內部的情況相比，可減小自天線6向被處理物W1的輻射熱的影響。藉此，亦可對包含膜材料的被處理物W1進行電漿處理。天線6以與收容於處理室21的被處理物W1的表面實質上平行的方式配置。The antenna 6 has a linear shape, is installed outside the vacuum container 2 , and is supported by the mechanism part 7 so as to face the magnetic field introduction window 3 and extend in the Y-axis direction. By disposing the antenna 6 outside the vacuum vessel 2 , compared with the case where the antenna 6 is disposed inside the vacuum vessel 2 , the influence of radiated heat from the antenna 6 to the object W1 can be reduced. Thereby, the object to be processed W1 including the membrane material can also be subjected to plasma treatment. The antenna 6 is arranged substantially parallel to the surface of the object W1 accommodated in the processing chamber 21 .

天線6若經由機構部7自高頻電源8被施加高頻電力，則產生高頻磁場。藉此，於被處理室21包圍的空間產生感應電場，於所述空間中生成感應耦合型的電漿P1。自天線6產生的高頻磁場透過電介質板5及多個狹縫41而被供給至處理室21。When high-frequency power is applied from the high-frequency power supply 8 via the mechanism unit 7 , the antenna 6 generates a high-frequency magnetic field.

In the connection part C1, it is preferable that the first circular plate C11 and the second circular plate C12 can relatively rotate, and the first circular plate C11 and the second circular plate C12 constitute a capacitor. Thereby, on the basis of reducing the reactance caused by the antenna 6 by the capacitor, the antenna 6 can be moved parallel along the magnetic field introduction window 3 by the relative rotation of the first circular plate C11 and the second circular plate C12. structure. The details are explained below.

如圖3所示，連結部C1具有包含樹脂的框體B1。框體B1對第一圓板C11以及第二圓板C12隔著間隙G1平行地進行保持，並且將其支持為能夠相互地旋轉，以使第一圓板C11與第二圓板C12構成平行平板電容器。藉此，第一圓板C11與第二圓板C12於連結部C1能夠相互地旋轉，並且可構成平行平板電容器。於框體B1的內部，相互空開間隔且平行地形成有凹部71、凹部72。凹部71、凹部72分別呈環狀地形成於框體B1的內部。第一圓板C11進入凹部71，且第二圓板C12進入凹部72。As shown in FIG. 3 , the connection part C1 has a frame B1 made of resin. The frame B1 holds the first circular plate C11 and the second circular plate C12 in parallel across the gap G1 and supports them so as to be rotatable with each other so that the first circular plate C11 and the second circular plate C12 form a parallel flat plate. capacitor. Thereby, the first circular plate C11 and the second circular plate C12 can rotate with each other at the connecting portion C1, and can form a parallel plate capacitor. Inside the frame B1, recessed portions 71 and 72 are formed in parallel and spaced apart from each other. The recessed portions 71 and 72 are each annularly formed inside the frame B1. The first circular plate C11 enters the recess 71 , and the second circular plate C12 enters the recess 72 .

於框體B1的兩側形成有開口部73、開口部74，旋轉軸A12進入開口部73，且旋轉軸A22進入開口部74。於開口部73與旋轉軸A12之間設置有密封構件75，於開口部74與旋轉軸A22之間設置有密封構件76。密封構件75、密封構件76用於防止框體B1的內部所填充的冷卻液洩漏至框體B1的外部，例如為O型環。Openings 73 and 74 are formed on both sides of the frame B1.

A sealing member 75 is provided between the opening 73 and the rotating shaft A12, and a sealing member 76 is provided between the opening 74 and the rotating shaft A22. The sealing members 75 and 76 are used to prevent the cooling liquid filled in the inside of the frame B1 from leaking to the outside of the frame B1, and are, for example, O-rings.

於天線6、臂A1～臂A6及連結部C1～連結部C4形成有供冷卻液流通的流路FL1。於連結部C1中，於旋轉軸A12、旋轉軸A22的內部形成有流路FL1。藉此，由於可抑制天線6、臂A1～臂A6及連結部C1～連結部C4的發熱，因此可降低自天線6、臂A1～臂A6及連結部C1～連結部C4對被處理物W1造成的熱影響。A flow path FL1 through which coolant flows is formed in the antenna 6, the arms A1 to A6, and the connecting portions C1 to C4. In the connection part C1, a flow path FL1 is formed inside the rotation shaft A12 and the rotation shaft A22. Thereby, since the heat generation of the antenna 6, the arms A1 to A6, and the connecting portions C1 to C4 can be suppressed, the impact on the object W1 to be processed from the antenna 6, the arms A1 to A6, and the connecting portions C1 to C4 can be reduced.

天線6、臂A1～臂A6是於內部形成有供冷卻液流通的流路FL1的中空構造的管。藉由使冷卻液於形成於旋轉軸A12、旋轉軸A22的內部的流路FL1中流通，從而向框體B1的內部填充冷卻液。作為於流路FL1中流通的冷卻液，就電絕緣的觀點而言，較佳為高電阻的水，例如較佳為純水或與其接近的水。另外，作為該冷卻液，例如亦可使用氟系惰性液體等水以外的液體製冷劑。The antenna 6 and the arms A1 to A6 are hollow-structured tubes in which a flow path FL1 for cooling fluid is formed. By causing the coolant to flow through the flow path FL1 formed inside the rotating shafts A12 and A22, the coolant is filled into the inside of the frame B1. From the viewpoint of electrical insulation, the coolant flowing through the flow path FL1 is preferably high-resistance water, for example, pure water or water close to it. In addition, as the cooling liquid, a liquid refrigerant other than water, such as a fluorine-based inert liquid, may be used.

藉由馬達M1進行旋轉，旋轉軸A12進行旋轉，與旋轉軸A12連接的直線部A11繞與Y軸方向平行且沿著旋轉軸A12的軸進行旋轉。藉由馬達M2進行旋轉，旋轉軸A22進行旋轉，與旋轉軸A22連接的直線部A21繞與Y軸方向平行且沿著旋轉軸A22的軸進行旋轉。When the motor M1 rotates, the rotation axis A12 rotates, and the linear portion A11 connected to the rotation axis A12 rotates around an axis parallel to the Y-axis direction and along the rotation axis A12. When the motor M2 rotates, the rotation axis A22 rotates, and the linear portion A21 connected to the rotation axis A22 rotates around an axis parallel to the Y-axis direction and along the rotation axis A22.

控制部10藉由馬達M1、馬達M2的旋轉角度對天線6的平行移動進行控制。控制部10向馬達M1、馬達M2發送控制訊號，以使天線6沿著圖1所示的平面F1平行移動。藉由利用馬達M1、馬達M2使連結部C1的第一圓板C11與第二圓板C12相對地旋轉，可藉由控制部10容易地進行基於馬達M1、馬達M2的旋轉動作的天線6的定位。連結部C2～連結部C4的剖面結構與圖3所示的連結部C1的剖面結構相同。馬達M2亦可設置於旋轉軸A23上而非設置於旋轉軸A22上。The control unit 10 controls the parallel movement of the antenna 6 through the rotation angles of the motors M1 and M2. The control unit 10 sends control signals to the motors M1 and M2 to move the antenna 6 in parallel along the plane F1 shown in FIG. 1 . By relatively rotating the first disk C11 and the second disk C12 of the connection part C1 using the motors M1 and M2, the control part 10 can easily perform the operation of the antenna 6 based on the rotation operation of the motors M1 and M2. position. The cross-sectional structure of the connection parts C2 to C4 is the same as the cross-sectional structure of the connection part C1 shown in FIG. 3 . The motor M2 may also be disposed on the rotation axis A23 instead of the rotation axis A22.

藉由以上所述，於電漿處理裝置1中，由於產生高頻磁場的天線6相對於設置於真空容器2的壁面22的磁場導入窗3而平行移動，因此可對被處理物W1均勻地進行電漿處理。另外，由於機構部7使天線6於真空容器2的外部平行移動，因此可抑制於處理室21內設置移動機構時顆粒的產生。As described above, in the plasma processing apparatus 1, the antenna 6 that generates a high-frequency magnetic field moves in parallel with respect to the magnetic field introduction window 3 provided on the wall surface 22 of the vacuum container 2, so that the object W1 to be processed can be uniformly Perform plasma treatment. In addition, since the mechanism part 7 moves the antenna 6 in parallel outside the vacuum container 2, it is possible to suppress the generation of particles when a moving mechanism is installed in the processing chamber 21.
