Description

包括帶狀磁鐵的等離子產生源及利用此的薄膜沉積系統Plasma generating source including strip magnet and thin film deposition system using the same

本發明係關於等離子體產生源及其應用,尤其係有關於利用永久磁鐵的排列產生高密度等離子體之等離子體產生源及利用此可實現高效率、大面積的濺射裝置和產生高通量中性粒子束的中性粒子束產生源以及組合濺射裝置和高通量中性粒子束產生源的薄膜沉積系統。
The present invention relates to a plasma generating source and an application thereof, and more particularly to a plasma generating source for generating a high-density plasma by arranging permanent magnets, and using the same to realize a high-efficiency, large-area sputtering apparatus and generating high-flux Neutral particle beam generation source for neutral particle beam and thin film deposition system for combined sputtering device and high flux neutral particle beam generation source.

等離子體具有多種應用,尤其在形成薄膜的技術中成為重要的技術要素。在半導體、OLED、太陽能電池、LED、鑽石薄膜等尖端材料領域中,需求高品質薄膜沉積,而產生能夠滿足這種需求的大面積、高密度等離子體是尤為重要的技術。Plasma has a variety of applications, particularly as an important technical element in the art of forming thin films. In the field of advanced materials such as semiconductors, OLEDs, solar cells, LEDs, and diamond films, high-quality thin film deposition is required, and a large-area, high-density plasma capable of meeting such demands is a particularly important technology.

在形成適用於最近應用頻率增大的可撓性電子元件,即,可撓性顯示器、可撓性照明、可撓性太陽能電池、可撓性二次電池等的薄膜時,需要能夠在大面積上生成等離子體的同時最小化因等離子體而產生的高能量粒子和等離子體電子導致的薄膜損傷的濺射技術。而且,還需要能夠在低溫下沉積高品質薄膜的低溫技術,以能夠使用可撓性塑膠基板。When forming a flexible electronic component suitable for a recent application frequency increase, that is, a flexible display, a flexible illumination, a flexible solar cell, a flexible secondary battery, or the like, it is required to be able to be used in a large area. A sputtering technique that minimizes plasma damage caused by high energy particles and plasma electrons generated by plasma. Moreover, there is a need for a low temperature technology capable of depositing a high quality film at a low temperature to enable the use of a flexible plastic substrate.

習知的磁控管濺射技術是在靶上施加-500V以上的高電壓而同時解決等離子體產生和離子加速的等離子體產生電力和離子加速電壓被統一的技術。在如此的磁控管濺射的等離子體產生電力和離子加速電壓被統一的習知技術中,需要向靶施加高電壓,因此無法避免高能量粒子的產生。如果為了最小化高能量粒子的產生而減少靶施加電壓,則導致等離子體不穩定或者等離子體密度顯著降低,發生沉積速度顯著下降的問題。The conventional magnetron sputtering technique is a technique in which a high voltage of -500 V or more is applied to a target while solving plasma generation and ion acceleration of plasma generation and ion acceleration. In such a conventional technique in which the plasma generation power and the ion acceleration voltage of the magnetron sputtering are unified, it is necessary to apply a high voltage to the target, so that generation of high energy particles cannot be avoided. If the target applied voltage is reduced in order to minimize the generation of high-energy particles, the plasma is unstable or the plasma density is remarkably lowered, and a problem that the deposition rate is remarkably lowered occurs.

為了解決這種問題,需要分離等離子體產生電力和離子加速電壓而分別獨立控制的技術。若可以分離等離子體產生電力和離子加速電壓,則期望與靶施加電壓電平無關地在靶附近產生高密度等離子體時,這種期望可以實現,但滿足這種目的的大面積、高密度等離子體產生源的技術開發並不容易。In order to solve such a problem, it is necessary to separate the plasma to generate electric power and ion acceleration voltage and separately control the techniques. If it is possible to separate the plasma generating electric power and the ion accelerating voltage, it is desirable to achieve a high-density plasma in the vicinity of the target irrespective of the applied voltage level of the target, which is expected to be achieved, but a large-area, high-density plasma that satisfies this purpose. The development of technology for body production sources is not easy.

另外,為了在低溫下沉積高品質薄膜,需要能夠在薄膜被沉積的期間同時加熱薄膜表面的原子層的原子級加熱(atomic scale heating)技術,來代替習知的基板加熱。中性粒子束能夠執行原子級加熱,因而對於在低溫下沉積高品質薄膜來說是有利的技術,但中性粒子束為了發揮原子級加熱效果,需要產生高通量中性粒子束。由於習知的中性粒子束產生源中,等離子體限制器設置在中和反射板和基板之間,因此具有在中性粒子束到達基板時起到障礙物的作用的問題。In addition, in order to deposit a high-quality film at a low temperature, an atomic scale heating technique capable of simultaneously heating an atomic layer on the surface of the film during deposition of the film is required instead of the conventional substrate heating. The neutral particle beam is capable of performing atomic-level heating, and thus is advantageous for depositing a high-quality film at a low temperature, but in order to exert an atomic-level heating effect, the neutral particle beam needs to generate a high-flux neutral particle beam. In the conventional neutral particle beam generating source, the plasma limiter is disposed between the neutralization reflector and the substrate, and thus has a problem of acting as an obstacle when the neutral particle beam reaches the substrate.

為了解決習知的中性粒子束產生源的問題,需要在沒有等離子體限制器的情況下能夠最小化等離子體和基板的相互作用且能夠產生高通量中性粒子束的、能夠產生高密度等離子體的技術,但技術開發並不容易。In order to solve the problem of the conventional neutral particle beam generating source, it is necessary to minimize the interaction between the plasma and the substrate without a plasma limiter and to generate a high-flux neutral particle beam capable of generating high density. Plasma technology, but technology development is not easy.

據此,為了沉積可撓性電子元件(即,可撓性顯示器、可撓性照明、可撓性太陽能電池、可撓性二次電池等)的製造領域中所需要的薄膜,需要新的濺射裝置和沒有等離子體限制器的高通量中性粒子束產生源。只要開發出適合於新的薄膜的目的的大面積、高密度等離子體產生源,則可以容易地實現這種裝置。因此,大面積、高密度等離子體產生源的開發是核心技術,但目前為止還沒有達到令人滿意的水準。Accordingly, in order to deposit a film required for the manufacture of a flexible electronic component (ie, a flexible display, a flexible illumination, a flexible solar cell, a flexible secondary battery, etc.), a new splash is required. A high-throughput neutral beam generation source with a firing device and no plasma limiter. Such a device can be easily implemented as long as a large-area, high-density plasma generating source suitable for the purpose of a new film is developed. Therefore, the development of large-area, high-density plasma generation sources is a core technology, but it has not yet reached a satisfactory level.

另外,習知技術中,為了在高真空下得到高密度等離子體,利用永久磁鐵或者電磁鐵形成磁場,並照射微波而產生了電子迴旋共振(Electron Cyclotron Resonance, ECR))等離子體。但是,習知技術中,因磁場的結構,在約束(confinement)電子迴旋共振區域中所產生的高密度等離子體時存在問題。例如,將若干個永久磁鐵保持預定間隔排列而形成杯場(cups field)時,在杯場內形成的電子迴旋共振區域中產生的等離子體因曲線磁場和電場而進行漂移運動(drift motion)(例如,ExB漂移(E-cross-Bdrift)、磁場梯度漂移(gradient B drift),磁場曲率漂移(curvature drift)等),漂移運動的軌跡形成直線的發散軌跡(計曲線),據此等離子體,尤其是電子從磁鐵的兩端洩露而導致在等離子體的約束上發生問題。而且,在另一習知技術的示例中,由於形成杯場,為了解決等離子體的約束問題,調整了磁鐵的排列,但因不連續的磁場分佈,等離子體漂移運動形成不連續的軌跡,因此存在等離子體約束效果下降的問題。Further, in the prior art, in order to obtain a high-density plasma under a high vacuum, a permanent magnet or an electromagnet is used to form a magnetic field, and a microwave is irradiated to generate an Electron Cyclotron Resonance (ECR) plasma. However, in the prior art, there is a problem in the high-density plasma generated in the confinement electron cyclotron resonance region due to the structure of the magnetic field. For example, when a plurality of permanent magnets are arranged at a predetermined interval to form a cups field, the plasma generated in the electron cyclotron resonance region formed in the cup field is subjected to drift motion due to a curved magnetic field and an electric field ( For example, ExB drift (E-cross-Bdrift), gradient B drift, curvature drift, etc., the trajectory of the drift motion forms a straight divergence trajectory (calculation curve), according to which the plasma In particular, electrons leak from both ends of the magnet, causing problems in the constraints of the plasma. Moreover, in another example of the prior art, since the cup field is formed, the arrangement of the magnets is adjusted in order to solve the plasma constraint problem, but the plasma drift motion forms a discontinuous trajectory due to the discontinuous magnetic field distribution, There is a problem that the plasma confinement effect is lowered.

另外,在習知技術中,在微波照射裝置和等離子體之間使用介電體視窗維持真空的同時,射入了微波。但是,在這種等離子體產生源進行沉積技術時,沉積物質將鍍覆介電體視窗,由此顯著地減少微波的透過率而減小等離子體密度,因而存在弱化技術的可靠度之問題。
Further, in the prior art, a microwave is applied between the microwave irradiation device and the plasma while maintaining a vacuum using a dielectric window. However, when such a plasma generating source performs a deposition technique, the deposited material will plate the dielectric window, thereby significantly reducing the transmittance of the microwave and reducing the plasma density, and thus there is a problem of reliability of the weakening technique.

以下,參照所附圖式,對本發明的優選實施例進行詳細的說明。Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

第1a圖中示出了本發明的等離子體產生源的構成。The configuration of the plasma generating source of the present invention is shown in Fig. 1a.

提供產生等離子體的空間的等離子體腔100的側壁上安裝有一對以上的帶狀磁鐵400,在等離子體腔100的上端安裝有微波照射裝置200(亦可稱為發射器(launcher),由所述微波照射裝置200向等離子體腔100內釋放微波。A pair of strip magnets 400 are mounted on the side wall of the plasma chamber 100 providing the plasma generating space, and a microwave irradiation device 200 (also referred to as a launcher) is attached to the upper end of the plasma chamber 100, and the microwave is The illumination device 200 releases microwaves into the plasma chamber 100.

尤其,本發明中,使從所述微波照射裝置200朝等離子體腔100內入射微波的位置形成為完整的開口部,而不是設置介電體視窗,據此解決了在沉積技術進行過程中沉積物污染視窗而導致微波透過率下降的問題。In particular, in the present invention, the position at which the microwave is incident from the microwave irradiation device 200 into the plasma chamber 100 is formed as a complete opening portion instead of providing a dielectric window, thereby solving the deposition during the deposition process. The problem of polluting the window and causing a decrease in microwave transmittance.

第1b圖和第1c圖為設置於等離子體產生源外壁上的一對帶狀磁鐵400的平面圖。即,上下排列A類型的帶狀磁鐵(第1b圖)和B類型的帶狀磁鐵(第1c圖)而能夠形成如第1a圖的形狀的磁場。這種帶狀磁鐵可以佈置多對,而不是只佈置一對,據此在等離子體產生空間內使如第1a圖的曲線連續地佈置。顯然,第1b圖和第1c圖中表示出的帶狀磁鐵可以構成為圓形或橢圓軌跡,或者任意的封閉的多邊形。所述磁場無間斷地連續,這源於帶狀磁鐵400本身具有連續的構成,而這種連續的結構源於將微波通過上端開口部入射,而不是通過等離子體腔100的側壁入射。連續形成的磁場捕獲所產生的等離子體的電子,使其沿著等離子體腔的側壁形成環形(toroidal)軌跡而連續進行漂移運動(drift motion),從而可以顯著地提高等離子體約束(plasma confinement)效果。即,平均地觀察電子的運動時,如第1d圖的剖切立體圖所示,表現出連續的回歸軌跡,從而可以顯著地提高等離子體約束效果。Figs. 1b and 1c are plan views of a pair of strip magnets 400 provided on the outer wall of the plasma generation source. In other words, the magnetic field of the shape of FIG. 1a can be formed by arranging the strip magnets of the A type (Fig. 1b) and the strip magnets of the B type (Fig. 1c) vertically. Such a strip magnet may be arranged in a plurality of pairs instead of only one pair, whereby the curves as in Fig. 1a are successively arranged in the plasma generating space. Obviously, the strip magnets shown in Figures 1b and 1c can be constructed as circular or elliptical tracks, or as arbitrary closed polygons. The magnetic field is continuous without interruption, which results from the continuous configuration of the strip magnet 400 itself, which is derived from the incidence of microwaves through the upper end opening rather than through the sidewalls of the plasma chamber 100. The continuously formed magnetic field captures the electrons of the generated plasma, causing a toroidal trajectory along the sidewall of the plasma chamber to continuously perform drift motion, thereby significantly improving the plasma confinement effect. . That is, when the movement of electrons is observed on average, as shown in the cutaway perspective view of Fig. 1d, a continuous regression trajectory is exhibited, and the plasma confinement effect can be remarkably improved.

等離子體腔100可以是圓柱形、具有橢圓軌跡的底面的圓柱形或者具有多邊形底面的多棱柱形,所述帶狀磁鐵400根據等離子體腔100的結構以圓形、橢圓軌跡、四邊形、除此之外的其他各種形狀安裝於等離子體腔100的側壁,並在等離子體腔100之內形成電子迴旋共振(Electron Cyclotron Resonance, ECR)磁場。在此,電子迴旋共振磁場Bres如以下數學式。The plasma chamber 100 may be cylindrical, cylindrical with a bottom surface having an elliptical trajectory or a polygonal prism having a polygonal bottom surface, and the strip magnet 400 has a circular shape, an elliptical trajectory, a quadrangle, and the like according to the structure of the plasma chamber 100. Various other shapes are mounted to the sidewalls of the plasma chamber 100 and form an Electron Cyclotron Resonance (ECR) magnetic field within the plasma chamber 100. Here, the electron cyclotron resonance magnetic field Bres is as follows.

f:微波頻率,e:電子電荷,me:電子品質f: microwave frequency, e: electronic charge, me: electronic quality

而且,由微波照射裝置200照射的微波頻率使用大於等離子體離子頻率的頻率。在此,等離子體離子頻率Ωi如以下數學式。Moreover, the microwave frequency irradiated by the microwave irradiation device 200 uses a frequency greater than the plasma ion frequency. Here, the plasma ion frequency Ωi is as follows.

ni:離子密度,Z:原子序數,e:電子電荷,mi:離子品質Ni: ion density, Z: atomic number, e: electron charge, mi: ion quality

The bulk density, and can produce such a high density plasma over a large area. Further, a high-density plasma can be generated under a low-pressure high vacuum of 1 mTorr or less, whereby the average free path of the particles is increased, thereby facilitating application.

另外,可以根據需要,將產生所述等離子體的微波照射裝置200的微波照射模式調節為脈衝模式或連續模式而拓寬應用性。Further, the microwave irradiation mode of the microwave irradiation device 200 that generates the plasma can be adjusted to a pulse mode or a continuous mode as needed to broaden the applicability.

具體實施方式detailed description

以下,詳細說明根據第1a圖至第1d圖的等離子體產生源的變形實施例及基於其應用的濺射裝置、中性粒子束產生源以及薄膜沉積系統。Hereinafter, a modified embodiment of the plasma generating source according to Figs. 1a to 1d and a sputtering apparatus, a neutral particle beam generating source, and a thin film deposition system based thereon will be described in detail.

從上方觀察第1a圖和第1d圖的微波照射裝置200時,呈現出如圓形、橢圓形、利用圓形、橢圓形的軌道形或四邊形的形狀。第2圖中示出在所述微波照射裝置200上形成狹縫250的情形,第3圖中示出在圓環形微波照射裝置200中形成狹縫的情形,第4圖示出四邊形或圓柱形微波照射裝置200,且如此的微波照射裝置200可以設置多個而增強輸出。When the microwave irradiation device 200 of Fig. 1a and Fig. 1d is viewed from above, a shape such as a circular shape, an elliptical shape, a circular or elliptical orbital shape or a quadrangular shape is exhibited. Fig. 2 shows a case where the slit 250 is formed on the microwave irradiation device 200, Fig. 3 shows a case where a slit is formed in the circular microwave irradiation device 200, and Fig. 4 shows a quadrangle or a cylinder. The microwave irradiation device 200 is shaped, and such a microwave irradiation device 200 can be provided in plurality to enhance the output.

參照第5圖,示出了應用所述等離子體產生源的濺射裝置800。所述濺射裝置800的特徵在於,微波的頻率大於等離子體離子頻率,因此可以不影響等離子體離子運動而加熱電子,由此產生等離子體,且施加於所述靶700、710、720的偏置電壓以低於等離子體離子頻率的頻率施加而可以調整入射於靶的離子的能量,由此分離等離子體產生電力和離子加速電壓。所述濺射裝置800通過使等離子體產生電力和離子加速電壓二元化,從而與靶偏置電壓無關地維持穩定的高密度等離子體,據此區別於在低靶施加電壓下等離子體變得不穩定的習知的濺射裝置。而且,由於習知的濺射設備的靶偏置電壓高,因此產生高能量粒子而損傷薄膜,與此相比,本實施例的濺射裝置800能夠減小靶偏置電壓,因此具有能夠最小化上述問題的優點。Referring to Fig. 5, a sputtering apparatus 800 to which the plasma generating source is applied is shown. The sputtering apparatus 800 is characterized in that the frequency of the microwave is greater than the plasma ion frequency, so that the electrons can be heated without affecting the movement of the plasma ions, thereby generating a plasma, and the bias applied to the targets 700, 710, 720 The applied voltage is applied at a frequency lower than the plasma ion frequency to adjust the energy of the ions incident on the target, thereby separating the plasma generating power and the ion accelerating voltage. The sputtering apparatus 800 maintains a stable high-density plasma irrespective of the target bias voltage by binarizing the plasma generation power and the ion acceleration voltage, thereby distinguishing that the plasma becomes at a low target application voltage. An unstable conventional sputtering device. Moreover, since the target bias voltage of the conventional sputtering apparatus is high, high-energy particles are generated to damage the thin film, the sputtering apparatus 800 of the present embodiment can reduce the target bias voltage, and thus has the smallest The advantages of the above problems.

由於能夠在設置於等離子體腔側壁的靶700、710附近的磁場產生高密度等離子體,據此能夠期待高效率的濺射。Since high-density plasma can be generated in a magnetic field in the vicinity of the targets 700 and 710 provided on the side wall of the plasma chamber, high-efficiency sputtering can be expected.

不僅如此,由於是帶狀磁鐵400的磁場結構,在靶720的附近形成非常均勻的高密度等離子體分佈,由此靶720的蝕刻分佈均勻,能夠提高靶720的使用效率。而且,能夠構成大面積的所述靶720,這源自等離子體分佈可以在大面積上以高密度形成。Moreover, since it is the magnetic field structure of the strip magnet 400, a very uniform high-density plasma distribution is formed in the vicinity of the target 720, whereby the etching distribution of the target 720 is uniform, and the use efficiency of the target 720 can be improved. Moreover, it is possible to constitute the large-area target 720, which is derived from the plasma distribution which can be formed at a high density over a large area.

另外,本濺射裝置800的靶700、710、720的偏置電壓可以根據技術的目的進行多種變化(直流電壓、交流電壓、直流脈衝、交流脈衝,或混合直流電壓、交流電壓、直流脈衝、交流脈衝而形成的電壓等),據此可以調節薄膜的特性。In addition, the bias voltages of the targets 700, 710, and 720 of the sputtering apparatus 800 can be variously changed according to the purpose of the technology (DC voltage, AC voltage, DC pulse, AC pulse, or mixed DC voltage, AC voltage, DC pulse, The voltage formed by the alternating pulse, etc., according to which the characteristics of the film can be adjusted.

而且,與上面並排設置的靶720和設置於側壁的靶700、710分別由不同的物質構成,從而提供可同時蒸鍍主物質和摻雜物的便利性。Moreover, the target 720 disposed side by side and the targets 700, 710 disposed on the side walls are respectively composed of different substances, thereby providing convenience in simultaneously evaporating the main substance and the dopant.

作為具體例,從一個靶700形成Zn,從另一個靶710形成In2O3,從又一個靶720形成Ga2O3,從而可以在基板上形成IGZO。在如此的排列中,具有可以最小化因負氧離子引起的薄膜損傷的同時能夠提高沉積速度的優點。As a specific example, Zn is formed from one target 700, In 2 O 3 is formed from the other target 710, and Ga 2 O 3 is formed from the other target 720, so that IGZO can be formed on the substrate. In such an arrangement, there is an advantage that the deposition speed can be improved while minimizing damage of the film due to negative oxygen ions.

設置於等離子體腔內壁的靶700、710可以以輻射狀佈置若干個短片,在等離子體腔中以水平面佈置的靶720可以貼附於等離子體腔的上面或佈置於腔內中央部,且其也可以由多個短片構成,雖然靶可以由多種不同物質構成,但為了實現高速、高效率、均勻的薄膜沉積,可以是調整排列的相同的物質。The targets 700, 710 disposed on the inner wall of the plasma chamber may be arranged in a radial arrangement of a plurality of short films, and the target 720 arranged in a horizontal plane in the plasma chamber may be attached to the plasma chamber or disposed at the central portion of the chamber, and it may also It is composed of a plurality of short films, and although the target can be composed of a plurality of different substances, in order to achieve high-speed, high-efficiency, uniform film deposition, the same substance can be adjusted.

據此,靶的構成(大面積靶等)比較自由,設置於等離子體腔內壁的靶700、710被由帶狀磁鐵400產生的磁場包圍,由此能夠在靶附近產生高密度等離子體,從而可以實現高效率的濺射。According to this configuration, the target configuration (large-area target or the like) is relatively free, and the targets 700 and 710 provided on the inner wall of the plasma chamber are surrounded by the magnetic field generated by the strip-shaped magnet 400, whereby high-density plasma can be generated in the vicinity of the target. High efficiency sputtering can be achieved.

而且,如此地在等離子體腔內壁設置多個靶700、710時,若將等離子體腔100構成為具有橢圓軌跡的底面的圓柱形或多棱柱,則設置多個靶以使薄膜的構成要素的數量和含量變為最佳時非常有利,還具有能夠調整由帶狀磁鐵400產生的磁場效果的優點。Further, when a plurality of targets 700, 710 are disposed on the inner wall of the plasma chamber, if the plasma chamber 100 is configured as a cylindrical or polygonal prism having a bottom surface of an elliptical trajectory, a plurality of targets are disposed so that the number of constituent elements of the thin film It is advantageous when the content is optimized, and there is an advantage that the effect of the magnetic field generated by the strip magnet 400 can be adjusted.

而且,本實施例的濺射裝置在高真空下產生高密度等離子體,由此濺射的粒子的直進性得到提高,從而在進行具有溝圖案的薄膜沉積時,可以提高縱橫比(aspect ratio)。Moreover, the sputtering apparatus of the present embodiment generates a high-density plasma under high vacuum, whereby the straightness of the sputtered particles is improved, so that the aspect ratio can be improved when performing film deposition having a groove pattern. .

本實施例的濺射裝置可獨立調節等離子體產生電力和離子加速電壓,並根據利用帶狀磁鐵400形成的磁場,約束等離子體帶電粒子,即便沒有專門的等離子體限制器,也能夠最小化等離子體-基板的相互作用,由此能夠最小化由等離子體引起的薄膜損傷。但是,本領域通常知識者顯然可以知道,根據需要,可以在腔臨界處增設等離子體限制器。The sputtering apparatus of the present embodiment can independently adjust the plasma generating electric power and the ion accelerating voltage, and confine the plasma charged particles according to the magnetic field formed by the strip magnet 400, and can minimize the plasma even without a special plasma limiter. The body-substrate interaction, thereby minimizing film damage caused by plasma. However, it will be apparent to those skilled in the art that a plasma limiter can be added at the critical point of the chamber as needed.

第6圖示出將所述濺射裝置800變形的中性粒子束產生源900的構成。Fig. 6 shows the configuration of a neutral particle beam generating source 900 that deforms the sputtering apparatus 800.

在濺射裝置800中以由導電性高的物質構成的中和反射板300替代靶700、710、720時,形成中性粒子束產生源900。向由鎢等金屬、矽膠、石墨等導電性高的物質構成的中和發射板上施加-100V以下的低偏置電壓,由此可以產生中性粒子束,而偏置電壓的多種模式可以與在所述濺射裝置中的構成相同地適用。根據本實施例的中性粒子束產生源900以與上述濺射裝置800相同的原理產生高密度等離子體,據此可產生高通量的中性粒子束。本實施例的中性粒子束產生源即便不設置等離子體限制器也能夠最小化等離子體-基板的相互作用,因此區別於習知的中性粒子束產生源。而且,也會相同地體現出由高真空下產生的高密度等離子體引起的中性粒子束的高通量的優點和由平均自由行程的增加而產生的優點。但是,根據需要可以在腔臨界處增設等離子體限制器,這對於本領域通常知識者來說是顯而易見的。When the neutralization reflector 300 made of a highly conductive material is used in the sputtering apparatus 800 instead of the targets 700, 710, and 720, a neutral particle beam generation source 900 is formed. A low-bias voltage of -100 V or less is applied to a neutralization emitter plate made of a highly conductive material such as a metal such as tungsten, tantalum or graphite, whereby a neutral particle beam can be generated, and various modes of the bias voltage can be used. The configuration in the sputtering apparatus is similarly applied. The neutral particle beam generating source 900 according to the present embodiment generates a high-density plasma in the same principle as the above-described sputtering apparatus 800, whereby a high-flux neutral particle beam can be generated. The neutral particle beam generation source of the present embodiment can minimize the plasma-substrate interaction even without providing a plasma limiter, and thus is different from the conventional neutral particle beam generation source. Moreover, the advantages of the high flux of the neutral particle beam caused by the high-density plasma generated under high vacuum and the advantage of the increase in the average free path are also exhibited in the same manner. However, it is possible to add a plasma limiter at the critical point of the cavity as needed, as will be apparent to those of ordinary skill in the art.

第7圖示出組合所述濺射裝置800和中性粒子產生源900而實現的薄膜沉積系統1000的一實施例。FIG. 7 illustrates an embodiment of a thin film deposition system 1000 implemented by combining the sputtering apparatus 800 and a neutral particle generating source 900.

根據所述薄膜沉積系統1000,通過濺射裝置800提供構成薄膜的粒子的同時通過中性粒子束追加提供形成薄膜所需的能量,由此具有在低溫技術下也能夠形成高品質的薄膜的優點。According to the thin film deposition system 1000, the particles constituting the thin film are supplied by the sputtering device 800 while additionally providing the energy required for forming the thin film by the neutral particle beam, thereby having the advantage of being able to form a high-quality thin film under low-temperature technology. .

在所述第7圖中,以一個濺射裝置800為中心在兩側分別設置一個(兩個)中性粒子束產生源900而構成了薄膜沉積系統1000,但還可以組合一個濺射裝置800和一個中性粒子束產生源900,顯然其組合方法可以由本領域通常知識者進行多樣的變更。In the seventh drawing, one (two) neutral particle beam generating sources 900 are respectively disposed on both sides centering on one sputtering apparatus 800 to constitute the thin film deposition system 1000, but a sputtering apparatus 800 may be combined. And a neutral particle beam generating source 900, it is obvious that the combined method can be variously changed by those skilled in the art.

第8圖示出在本發明的中性粒子產生源的構成中進一步包括限制器500的構成。雖然沒有限制器500也能夠最小化等離子體-基板的相互作用,但進一步設置限制器500之後,在中性粒子束從等離子體腔100射出到具有基板600的技術腔(未圖示)時,可以更徹底地清除被帶電的粒子。Fig. 8 shows a configuration in which the restrictor 500 is further included in the configuration of the neutral particle generating source of the present invention. Although the plasma-substrate interaction can be minimized without the limiter 500, after the restrictor 500 is further disposed, when the neutral particle beam is emitted from the plasma chamber 100 to the technical chamber (not shown) having the substrate 600, Remove charged particles more thoroughly.

另外,帶狀磁鐵400可以採用不是永久磁鐵的電磁鐵,此時,可以增加微波的頻率,據此可提高等離子體密度。Further, the strip magnet 400 may be an electromagnet which is not a permanent magnet. In this case, the frequency of the microwave can be increased, whereby the plasma density can be increased.

本發明的權利範圍依據申請專利範圍的記載來定義,並不局限於上述說明的實施例,本發明所屬領域中具有通常知識者可以在申請專利範圍記載的權利範圍之內進行多種變更和修改,這是顯而易見的。The scope of the present invention is defined by the scope of the claims, and is not limited to the embodiments described above, and those skilled in the art can make various changes and modifications within the scope of the claims. This is obvious.
