Description

具有複數之去耦合電漿源的半導體系統 Semiconductor system with a plurality of decoupled plasma sources

本發明係關於一種半導體處理系統,且尤其有關於一種具有複數之去耦合電漿源的半導體處理系統。 This invention relates to a semiconductor processing system, and more particularly to a semiconductor processing system having a plurality of decoupled plasma sources.

用於半導體裝置製造中之薄膜處理的電漿源常因無法分別控制電漿中之離子及自由基濃度,而無法達到最期望之乾式蝕刻條件。例如,在一些應用中,電漿蝕刻之期望條件將藉由增加電漿中之離子濃度而同時將自由基濃度維持在固定位準來達成。然而,此類型之離子濃度對自由基濃度的獨立控制無法使用典型地用於薄膜處理之一般電漿源來達成。而本發明係於本文內呈現。 Plasma sources used in thin film processing in the manufacture of semiconductor devices often fail to achieve the most desirable dry etching conditions due to the inability to separately control the ion and radical concentrations in the plasma. For example, in some applications, the desired conditions for plasma etching will be achieved by increasing the ion concentration in the plasma while maintaining the free radical concentration at a fixed level. However, independent control of this type of ion concentration versus free radical concentration cannot be achieved using a typical plasma source typically used for thin film processing. The invention is presented herein.

本發明之其他態樣及優點將由以下藉由本發明之實例加以說明的詳細敘述結合隨附圖式而變得更加明顯。 Other aspects and advantages of the invention will be apparent from the description of the appended claims.

在以下的敘述中,為了提供對於本發明之透徹瞭解而提出許多具體細節。然而,對於熟悉本技術領域者將顯而易見,本發明可在不具有這些具體細節之一些或全部者的情況下加以實施。在其他情況下,為了不非必要地混淆本發明,故並未詳細敘述廣為人知之處理操作。 In the following description, numerous specific details are set forth in order to provide a thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention may be practiced without some or all of these specific details. In other instances, well-known processing operations have not been described in detail in order not to obscure the invention.

為了在電漿處理區域內達成離子及自由基濃度之去耦合控制,在待處理基板設於電漿處理區域內的情況下,本發明之各種實施例包含可使用獨立控制參數獨立地加以控制的例如電漿腔室之二或更多類型之電漿生成裝置,該二或更多類型之電漿生成裝置係流體連接至該電漿處理區域。例如,在一實施例中,第一電漿腔室可受操作以產生具有高於離子濃度之自由基濃度的第一電漿。並且,在此示範實施例中,第二電漿腔室可受操作以產生具有高於自由基濃度之離子濃度的第二電漿。第一及第二電漿腔室二者均流體連接至相同的基板處理區域,使得第一電漿腔室受操作以控制基板處理區域內之一數量的自由基成份,且使得第 二電漿腔室受操作以控制基板處理區域內之一數量的離子成份。依此方式,第一電漿腔室受控制以調節基板處理區域中之離子濃度,且第二電漿腔室受控制以調節基板處理區域中之自由基濃度。 In order to achieve decoupling control of ion and radical concentrations in the plasma processing zone, various embodiments of the invention include independently controllable control parameters using independent control parameters where the substrate to be processed is disposed within the plasma processing zone.

For example, in an embodiment, the first plasma chamber can be operated to produce a first plasma having a free radical concentration above the ion concentration. Also, in this exemplary embodiment, the second plasma chamber can be operated to produce a second plasma having an ion concentration above the free radical concentration. The first and second plasma chambers are both fluidly coupled to the same substrate processing region such that the first plasma chamber is operated to control one of the number of free radical components in the substrate processing region, and The two plasma chambers are operated to control one of the number of ionic components in the substrate processing region. In this manner, the first plasma chamber is controlled to adjust the ion concentration in the substrate processing region, and the second plasma chamber is controlled to adjust the concentration of free radicals in the substrate processing region.

在一實施例中,此處所使用的用語「基板」係指半導體晶圓。然而應瞭解,在其他實施例中,此處所使用的用語「基板」可意指由藍寶石、GaN、GaAs或SiC、或其他基板材料所形成的基板,且可包含玻璃面板/基板、金屬箔、金屬薄片、聚合物材料、或類似物。並且,在各種實施例中,此處所指之「基板」可在形式、形狀、及/或尺寸上變更。例如,在一些實施例中,此處所指之「基板」可對應至200mm(毫米)半導體晶圓、300mm半導體晶圓、或450mm半導體晶圓。並且,在一些實施例中,此處所指之「基板」可對應至除了其他形狀之外的非圓形基板,例如用於平板顯示器之矩形基板、或類似物。此處所指之「基板」在各種示範實施例圖式中係以基板105表示。 In one embodiment, the term "substrate" as used herein refers to a semiconductor wafer. It should be understood, however, that in other embodiments, the term "substrate" as used herein may mean a substrate formed of sapphire, GaN, GaAs or SiC, or other substrate material, and may include a glass panel/substrate, metal foil, Metal foil, polymeric material, or the like.

獨立操作複數電漿腔室以提供反應性成份至共同基板處理區域實質上在共同基板處理區域內提供離子濃度相對自由基濃度的去耦合調整。在各種實施例中,在複數電漿腔室內產生不同類型之電漿係透過獨立控制連接至複數電漿腔室之電源及/或氣體供應器來達成。並且,在一些實施例中,可將複數電漿腔室之輸出設置成與基板處理區域流體連通之空間陣列。複數電漿腔室之輸出可彼此分散且彼此足夠接近地分隔,使得形成於複數電漿腔室內的不同類型電漿之不同反應性成份以實質上均勻之方式被供給至基板處理區域,以在基板處理區域內呈現實質上均勻的基板之處理。 Independently operating the plurality of plasma chambers to provide reactive components to the common substrate processing region provides substantially decoupling adjustment of ion concentration versus free radical concentration within the common substrate processing region. In various embodiments, generating different types of plasma within the plurality of plasma chambers is accomplished by independently controlling the power and/or gas supply connected to the plurality of plasma chambers. Also, in some embodiments, the output of the plurality of plasma chambers can be arranged in an array of spaces in fluid communication with the substrate processing region. The outputs of the plurality of plasma chambers may be dispersed from each other and spaced sufficiently close to each other such that different reactive components of different types of plasma formed in the plurality of plasma chambers are supplied to the substrate processing region in a substantially uniform manner to The process of presenting a substantially uniform substrate within the substrate processing region.

圖1顯示依據本發明之一實施例的利用暴露至共同基板處理區域之複數電漿腔室可達到的離子濃度與自由基濃度之間的關係。第一線301顯示產生於流體連接至共同基板處理區域的第一電漿腔室中之第一電漿中的離子濃度對自由基濃度之變異。在此實例中,第一電漿具有較離子濃度高之自由基濃度。第二線303顯示產生於流體連接至共同基板處理區域的第二電漿腔室中 之第二電漿中的離子濃度對自由基濃度之變異。在此實例中,第二電漿具有較自由基濃度高之離子濃度。因此,第一電漿係生成以主要供給自由基成份至基板處理區域,且第二電漿係生成以主要供給離子成份至基板處理區域。 1 shows the relationship between ion concentration and radical concentration achievable using a plurality of plasma chambers exposed to a common substrate processing region in accordance with an embodiment of the present invention. The first line 301 shows the variation in ion concentration versus radical concentration in the first plasma generated in the first plasma chamber fluidly connected to the common substrate processing region. In this example, the first plasma has a higher concentration of free radicals than the ion concentration. The second line 303 is shown in the second plasma chamber that is fluidly coupled to the common substrate processing region The variation of the ion concentration in the second plasma versus the concentration of the radical. In this example, the second plasma has a higher ion concentration than the free radical concentration. Therefore, the first plasma is generated to mainly supply the radical component to the substrate processing region, and the second plasma is generated to mainly supply the ion component to the substrate processing region.

透過獨立控制第一及第二電漿腔室,便可在基板處理區域內達成延伸於第一線301與第二線303之間的範圍內之實質上任何離子濃度對自由基濃度。例如,第二電漿腔室可單獨受操作以在基板處理區域內供給第一離子對自由基濃度比率305。當一齊使用時,第一電漿腔室可受操作以增加基板處理區域內之自由基濃度,而第二電漿腔室受操作以在基板處理區域內維持實質上穩定之離子濃度,藉此在基板處理區域內產生無法單獨利用第一或第二電漿腔室達成的第二離子對自由基濃度比率307。類似地,當一齊使用時,第二電漿腔室可受操作以減少基板處理區域內之離子濃度,而第一電漿腔室受操作以在基板處理區域內維持實質上穩定之自由基濃度,藉此在基板處理區域內產生無法單獨利用第一或第二電漿腔室達成的第三離子對自由基濃度比率309。 By independently controlling the first and second plasma chambers, substantially any ion concentration versus radical concentration extending within the range between the first line 301 and the second line 303 can be achieved in the substrate processing region. For example, the second plasma chamber can be individually operated to supply a first ion to radical concentration ratio 305 within the substrate processing region. When used together, the first plasma chamber can be operated to increase the concentration of free radicals in the substrate processing region while the second plasma chamber is operated to maintain a substantially stable ion concentration in the substrate processing region, thereby A second ion-to-radical concentration ratio 307 that cannot be achieved using the first or second plasma chamber alone is generated within the substrate processing region. Similarly, when used together, the second plasma chamber can be operated to reduce ion concentration in the substrate processing region while the first plasma chamber is operated to maintain a substantially stable free radical concentration in the substrate processing region. Thereby, a third ion pair radical concentration ratio 309 which cannot be achieved by using the first or second plasma chamber alone is generated in the substrate processing region.

進一步關於圖1,第一電漿腔室可單獨受操作以於基板處理區域內供給第四離子對自由基濃度比率311。當一齊使用時,第二電漿腔室可受操作以增加基板處理區域內之離子濃度,而第一電漿腔室受操作以在基板處理區域內維持實質上穩定之自由基濃度,藉此在基板處理區域內產生無法單獨利用第一或第二電漿腔室達成的第五離子對自由基濃度比率313。類似地,當一齊使用時,第一電漿腔室可受操作以減少基板處理區域內之自由基濃度,而第二電漿腔室受操作以在基板處理區域內維持實質上穩定之離子濃度,藉此在基板處理區域內產生無法單獨利用第一或第二電漿腔室達成的第六離子對自由基濃度比率315。 Further with respect to Figure 1, the first plasma chamber can be individually operated to supply a fourth ion pair radical concentration ratio 311 within the substrate processing region. When used together, the second plasma chamber can be operated to increase the ion concentration in the substrate processing region while the first plasma chamber is operated to maintain a substantially stable free radical concentration in the substrate processing region, thereby A fifth ion pair radical concentration ratio 313 that cannot be achieved using the first or second plasma chamber alone is generated in the substrate processing region. Similarly, when used together, the first plasma chamber can be operated to reduce the concentration of free radicals in the substrate processing region while the second plasma chamber is operated to maintain a substantially stable ion concentration in the substrate processing region. Thereby, a sixth ion pair radical concentration ratio 315 which cannot be achieved by using the first or second plasma chamber alone is generated in the substrate processing region.

基於前述內容,應瞭解在本發明之一實施例中,複數受獨立控制之電漿腔室係用以供給反應性成份至共同基板處理區域,以提供無法透過僅操作單一電漿腔室來達成的離子對自由基濃度比率。基於相關圖1之討論,應進一步察知,當將複數電漿 之反應性成份結合時,具有顯著不同離子對自由基濃度比率之複數電漿在基板處理區域內提供較廣的離子對自由基濃度比率之範圍。若干半導體基板處理系統係揭露於此,其提供自受獨立控制之複數電漿腔室輸出的反應性成份之空間性結合,以在基板處理區域內產生無法利用單一電漿腔室本身達成的反應性成份之結合。 Based on the foregoing, it will be appreciated that in one embodiment of the invention, a plurality of independently controlled plasma chambers are used to supply reactive components to a common substrate processing region to provide for inability to operate through a single plasma chamber. The ratio of ion to radical concentration. Based on the discussion in relation to Figure 1, it should be further observed that when multiple plasmas are to be When the reactive components are combined, the complex plasma having a significantly different ion to radical concentration ratio provides a broader range of ion to radical concentration ratios in the substrate processing region. A number of semiconductor substrate processing systems are disclosed herein that provide a spatial combination of reactive components from a plurality of independently controlled plasma chambers to produce a reaction in the substrate processing region that cannot be achieved with a single plasma chamber itself. a combination of sexual ingredients.

System 200C is a variation of system 200B of Figure 2B. in particular, The system 200C includes a discharge passage 111 formed between the first and second plasma chambers 101/102 to be supported from the processing region 106 toward the substrate 105 substantially perpendicular to the substrate holder 107. The direction of the surface extends away. In one embodiment, the exhaust passage 111 is open and unobstructed for gas to be expelled from the processing zone 106.

Also, the baffle structure 109 is sized to be smaller than the discharge passage 111 for the exhaust flow to pass through the discharge passage 111 around the baffle structure 109.

在圖2B及2C之示範實施例中,可將擋板結構109用以限制例如101、102之鄰接電漿腔室之間的流體及/或功率連通。此外,可將擋板結構109用以協助建立基板105範圍的離子及自由基之均勻度。如相關於圖2B及2C而提及,擋板結構109可在實質上垂直於基板支持件107之方向114上移動。擋板結構109在方向114上之此移動使垂直測量於擋板結構119與基板105之間的距離115得以調整。 In the exemplary embodiment of Figures 2B and 2C, the baffle structure 109 can be used to limit fluid and/or power communication between adjacent plasma chambers, such as 101, 102. In addition, the baffle structure 109 can be used to assist in establishing the uniformity of ions and radicals in the range of the substrate 105. As mentioned in relation to Figures 2B and 2C, the baffle structure 109 can be moved in a direction 114 that is substantially perpendicular to the substrate support 107. This movement of the baffle structure 109 in the direction 114 allows the distance 115 measured vertically between the baffle structure 119 and the substrate 105 to be adjusted.

在各種實施例中,擋板結構109與基板105之間的距離115可高達5cm。然而應瞭解,距離115為例如自第一及第二電漿腔室101/102發出之離子及自由基通量的其他參數之函數。在一示範實施例中,擋板結構109與基板105之間的距離115為約2cm。此外,儘管顯示於圖2B及2D之示範實施例中之擋板結構109在剖面上呈矩形,應瞭解擋板結構109仍可以其他形式呈現形狀,例如圓弧底部、具有角度之底部、錐形頂部等,以於處理區域106內達到特定功效,例如控制其中包含交叉流及紊流的處理氣體條件。 In various embodiments, the distance 115 between the baffle structure 109 and the substrate 105 can be as high as 5 cm. It should be understood, however, that distance 115 is a function of, for example, other parameters of ions and radical fluxes emanating from first and second plasma chambers 101/102. In an exemplary embodiment, the distance 115 between the baffle structure 109 and the substrate 105 is about 2 cm. Moreover, although the baffle structure 109 shown in the exemplary embodiment of Figures 2B and 2D is rectangular in cross-section, it should be understood that the baffle structure 109 can assume other shapes, such as a rounded bottom, an angled bottom, and a tapered shape.

在一些情況中,電漿內之自由基生成在試圖於電漿內主要產生離子時無法避免。在這些情況中,於主要目的為達成自電 漿運送離子成份時,自由基成份自所生成之電漿受到運送亦或多或少無法避免。再者,自電漿抽取離子意味離子源(即電漿)與處理區域(如處理區域106)之間的開口足夠大,使得鞘部並不抑制電漿抽取,並使得對於抽取介質壁的撞擊低,以不使離子中性化。在本發明之一實施例中,可將離子源區域實施為賦能出口區域,以提供輔助電子生成來增強自離子源抽取離子。例如,在一實施例中,可將暴露至處理區域的電漿腔室之出口區域定義為空心陰極,以增強出口區域本身內之離子生成,且相對應地增強自電漿腔室抽取離子。 In some cases, free radical formation within the plasma is unavoidable when attempting to primarily generate ions in the plasma. In these cases, the main purpose is to achieve self-power When the slurry transports the ionic components, the transport of the free radical components from the generated plasma is more or less unavoidable. Furthermore, extracting ions from the plasma means that the opening between the ion source (i.e., plasma) and the processing region (e.g., processing region 106) is sufficiently large that the sheath does not inhibit plasma extraction and causes impact on the walls of the extraction medium. Low to prevent neutralization of ions. In one embodiment of the invention, the ion source region can be implemented as an energization exit region to provide auxiliary electron generation to enhance extraction of ions from the ion source. For example, in one embodiment, the exit region of the plasma chamber exposed to the processing region can be defined as a hollow cathode to enhance ion generation within the exit region itself and correspondingly enhance extraction of ions from the plasma chamber.

圖2D顯示依據本發明之一實施例的第二電漿腔室102之變化例,其具有賦能出口區域225以增強離子抽取。然而應瞭解,可將第一及第二電漿腔室101/102之一者或二者定義成具有可賦能電漿出口區域225,該出口區域225係定義成提供輔助電子生成以增加離子抽取。在一實施例中,可賦能電漿出口區域225係定義為空心陰極。在此實施例之一版本中,出口區域225係由電極220所圍繞,該電極220可由DC功率、RF功率、或其組合供電。當來自電漿102A之反應性成份流過可賦能電漿出口區域225時,由電極220發出之功率將於出口區域225內釋放快速電子,此將因而導致流過出口區域225之處理氣體中的進一步離子化,藉此增強自電漿腔室102抽取離子。此外,由偏壓電極112橫跨處理區域106而施加的偏壓將用以自腔室102內之電漿102A及自出口區域225朝基板105拉引離子。 2D shows a variation of the second plasma chamber 102 having an energization exit region 225 to enhance ion extraction in accordance with an embodiment of the present invention. It should be understood, however, that one or both of the first and second plasma chambers 101/102 can be defined as having an energizable plasma outlet region 225 that is defined to provide auxiliary electron generation to increase ions. Extract. In an embodiment, the energizable plasma exit region 225 is defined as a hollow cathode. In one version of this embodiment, the exit region 225 is surrounded by an electrode 220 that can be powered by DC power, RF power, or a combination thereof. When the reactive component from the plasma 102A flows through the energizable plasma exit region 225, the power emitted by the electrode 220 will release rapid electrons in the exit region 225, which will thereby result in the flow of gas through the exit region 225. Further ionization, thereby enhancing extraction of ions from the plasma chamber 102. Additionally, the bias applied by the bias electrode 112 across the processing region 106 will be used to pull ions from the plasma 102A in the chamber 102 and from the exit region 225 toward the substrate 105.

Each of the second set of power delivery members 613 is coupled to receive a second power from the second power source 103B and to supply a second power to the associated one of the second set of plasma microchambers 603. In one embodiment, each of the second set of power delivery members 613 is defined as a coil that is formed to surround a given one of the second set of plasma microchambers 603. However, it should be understood that in other embodiments, the second set of power delivery members 613 can be defined as a form other than a coil. For example, in one embodiment, each of the second set of power delivery members 613 is defined as one or more electrodes configured and arranged to deliver a second power to the second set The plasma microchamber 603 is associated with it.

基板支持件107內之電極112係定義成施加偏壓橫跨基板支持件107與頂板組件601之下表面之間的處理區域106。流動通過第二氣體供應通道網路609而至第二組電漿微腔室603中(即至排出通道607中)的處理氣體係受拉引離開處理區域106,且不進入處理區域106。因此,由於第二組電漿微腔室603係形成於排出通道607內,所以形成於第二組電漿微腔室603內之自由基將循排出氣體流動路徑通過排出通道607。然而,形成於第二組電漿微腔室603內之離子將被電極112所施加橫跨處理區域106之偏壓拉至處理區域106中。依此方式,第二組電漿微腔室603可運作為處理區域106用之實質上純離子源。 The electrode 112 within the substrate support 107 is defined to apply a biasing across the processing region 106 between the substrate support 107 and the lower surface of the top plate assembly 601. The process gas system flowing through the second gas supply passage network 609 to the second set of plasma microchambers 603 (i.e., into the exhaust passage 607) is drawn away from the processing region 106 and does not enter the processing region 106. Therefore, since the second set of plasma microchambers 603 are formed in the discharge passage 607, the radicals formed in the second set of plasma microchambers 603 will follow the exhaust gas flow path through the discharge passage 607. However, ions formed in the second set of plasma microchambers 603 will be pulled into the processing region 106 by the bias applied by the electrodes 112 across the processing region 106. In this manner, the second set of plasma microchambers 603 can function as a substantially pure ion source for the processing zone 106.

應瞭解第一組電漿微腔室605間係以實質上平均之方式橫跨頂板組件601之下表面而散置有第二組電漿微腔室603。依此方式,在到達基板105前,於處理區域106內,來自第一組電漿微腔室605之反應性自由基成份可以實質上均勻之方式與來自第二組電漿微腔室603之離子成份混合。圖5B顯示依據本發明之一實施例的圖5A中標示之水平剖面視圖C-C。如圖5B所示,第一及第二組電漿微腔室605/603係以實質上平均之方式橫跨頂板組件601之下表面而分佈。 It will be appreciated that the first set of plasma microchambers 605 are interspersed with a second set of plasma microchambers 603 across the lower surface of the top plate assembly 601 in a substantially even manner. In this manner, the reactive radical components from the first set of plasma microchambers 605 can be substantially uniformly distributed from the second set of plasma microchambers 603 in the processing region 106 prior to reaching the substrate 105. Ion components are mixed. Figure 5B shows a horizontal cross-sectional view C-C of Figure 5A, in accordance with an embodiment of the present invention. As shown in FIG. 5B, the first and second sets of plasma microchambers 605/603 are distributed across the lower surface of the top plate assembly 601 in a substantially average manner.

應察知橫跨頂板組件601之下表面的第一及第二組電漿微腔室605/603之間距可在不同實施例之間加以改變。圖5C顯示依據本發明之一實施例的圖5B之水平剖面視圖的變化例,其中減少橫跨頂板組件601之下表面的第一及第二組電漿微腔室605/603之間的間距。圖5D顯示依據本發明之一實施例的圖5B之水平剖面視圖的變化例,其中增加橫跨頂板組件601之下表面的第一及第二組電漿微腔室605/603之間的間距。圖5E顯示依據本發明之一實施例的圖5B之水平剖面視圖的變化例,其中橫跨頂板組件601之下表面的第一及第二組電漿微腔室605/603之間的間距不相等。 It will be appreciated that the distance between the first and second sets of plasma microchambers 605/603 across the lower surface of the top plate assembly 601 can vary between different embodiments. 5C shows a variation of the horizontal cross-sectional view of FIG. 5B in which the spacing between the first and second sets of plasma microchambers 605/603 across the lower surface of the top plate assembly 601 is reduced, in accordance with an embodiment of the present invention. . Figure 5D shows a variation of the horizontal cross-sectional view of Figure 5B in which the spacing between the first and second sets of plasma microchambers 605/603 across the lower surface of the top plate assembly 601 is increased, in accordance with an embodiment of the present invention. . Figure 5E shows a variation of the horizontal cross-sectional view of Figure 5B in accordance with an embodiment of the present invention, wherein the spacing between the first and second sets of plasma microchambers 605/603 across the lower surface of the top plate assembly 601 is not equal.

如同圖2A-2G、3A-3E、4A-4E之實施例,在圖5A-5E 之實施例中,第一及第二電源103A/103B與第一及第二處理氣體供應器104A/104B可利用各種方式加以控制。在一實施例中,第一及第二電源103A/103B可獨立地加以控制。在一實施例中,第一及第二處理氣體供應器104A/104B可獨立地加以控制。在又另一實施例中,第一及第二電源103A/103B與第一及第二處理氣體供應器104A/104B均可獨立地加以控制。以下,應瞭解第一及第二組電漿微腔室605/603係定義成以同時之方式或脈衝方式操作。當以脈衝方式操作時,第一組電漿微腔室605或第二組電漿微腔室603係於給定時間受操作,且第一及第二組電漿微腔室605/603係以交替順序加以操作。 Like the embodiments of Figures 2A-2G, 3A-3E, 4A-4E, in Figures 5A-5E In an embodiment, the first and second power sources 103A/103B and the first and second process gas supplies 104A/104B can be controlled in a variety of ways. In an embodiment, the first and second power sources 103A/103B are independently controllable. In an embodiment, the first and second process gas supplies 104A/104B are independently controllable. In still another embodiment, the first and second power sources 103A/103B and the first and second process gas supplies 104A/104B are independently controllable. In the following, it should be understood that the first and second sets of plasma microchambers 605/603 are defined to operate in a simultaneous manner or in a pulsed manner. When operated in a pulsed manner, the first set of plasma microchambers 605 or the second set of plasma microchambers 603 are operated at a given time, and the first and second sets of plasma microchambers 605/603 are Operate in an alternating sequence.

在圖5A之實施例的情況中,應察知可使容許例如雙極性擴散的電漿自其生成區域逸出之驅動件與藉由反轉處理氣體流動方向而容許自由基逸入電漿區域中之驅動件相對。將頂部泵送增加至離子源(即至第二組電漿微腔室603)促進自電漿源本身更有效之離子抽取(較寬開口)及較大的離子/中性通量比率。此外,應瞭解在圖5A之腔室401的一實施例中,可進一步配置如先前相關於圖3A及4A所敘述的周圍通氣口427、流動節流裝置433、排出埠429、及排出泵431,以實現通過排出通道607的頂部排出流動之外的周圍流動。 In the case of the embodiment of Figure 5A, it will be appreciated that the drive member that allows for, for example, bipolar diffusion of plasma to escape from its generating region and the reverse flow of the process gas allow free radicals to escape into the plasma region. The drive parts are opposite. Increasing the top pumping to the ion source (i.e., to the second set of plasma microchambers 603) promotes more efficient ion extraction (wider openings) and larger ion/neutral flux ratios from the plasma source itself. In addition, it is to be understood that in an embodiment of the chamber 401 of FIG. 5A, the peripheral vent 427, the flow restriction 433, the discharge port 429, and the discharge pump 431 as previously described with respect to FIGS. 3A and 4A can be further configured. To achieve a peripheral flow outside the flow through the top of the discharge passage 607.

Also, different types of plasma sources can be pulsed to mitigate communication between adjacent plasma sources. Two-phase isoelectric plasma source types can also be operated with different gas mixtures to achieve higher ion flux from one plasma source and higher free radical flux from another plasma source. In one embodiment, where there is an array of mixed ion and radical plasma sources, each plasma source can be connected to its own independently controlled power and gas supply. And, in another embodiment, all of the ion plasma sources in the hybrid array can be connected to a common gas supply and a common power source, and all of the free radical plasma sources in the hybrid array can be connected to another gas supply.
