以下,明參照圖1至圖3,透過圖1至圖3說明本發明的半導體 襄置之製造裝置及半導體裝置之製造方法之—具體實施例。 如圖1所示,半導體裝置之製造裝置相鄰設置有—對搬入/搬出 口 11a、lib ’用以導入或取出基板。前處理腔室i2a、i2b係設置 在鄰接於各搬入/搬出口 11a、lib的位置上。前處理腔室i2a、12b 係用以在基板形成鎢薄膜之前,先對基板之表面進行洗淨之前 處理。又,成膜腔室13a、13b係設置在鄰接於前處理腔室i2a、 12b的位置上。成膜腔室13a、丨北係用以執行於基板上形成鎢薄 膜的成膜處理。熱處理腔室14係設置於成膜腔室13a、13b之間。 熱處理腔室14係用以對經過前處理之後的基板施加預定之熱處 理。在半導體裝置之製造裝置中’一對搬入/搬出口 ua、與 五個腔室12a、12b、13a、13b、14可構成環狀,但不以此為限。 201117297 半導體裝置之製造裝置的中央設置有轉移腔室(transfer chamber)15’當基板從二個搬入/搬出口iia、llb及五個腔室12a、 12b、13a、13b、14中之任一者朝下一個步驟移動時,基板將會 所通過轉移腔室15。 在I造半導體裝置時’作為成膜對象的基板將會從搬入/搬出 口 11a、lib被導入至製造裝置内。搬入/搬出口 lla、仙係相對 於被導入的基板而具有相同的功能。以下,將針對從搬入/搬出 口 11a導入基板的情況加以說明。基板上具有主動元件之一面設 置有絕緣膜’而絕緣層設置有形成配線的接觸孔或構成多層配 線的通孔。 當基板被導入於搬入/搬出口 11a之後,將會透過轉移腔室15 搬運至前處理腔室12a。前處理腔室12a係用以從位於設置在絕緣 層的接觸孔底部之基板表面、或是位於通孔之底部的配線表 面’去除掉與大氣中之氧反應而成的氧化物層。於前處理腔室 12a進行前處理之後’基板將會通過轉移腔室15而被搬運至熱處 理腔室14。熱處理腔室η係用以對基板上由於前處理而露出的 底層執行熱處理,以降低鎢薄膜與底層之界面的電阻。經過熱 處理之後’基板將會透過轉移腔室15搬運至成膜腔室13&。成膜 腔室13a係用以形成基板的接觸孔或通孔,並透過選擇性化學氣 相沉積法於基板的高導電性部位選擇性地形成鎢薄膜。 經過上述成膜處理之後,基板將會透過轉移腔室15被搬運至 搬入/搬出口 11 a ’並移出製造裝置外。至於基板從搬入/搬出口 i lb 搬運至製造裝置的情況則與從搬入/搬出口 lla搬入的情況相 同’會依序施行前處理腔室12b之前處理、熱處理腔室Η之熱處 理、以及成膜腔室13b之成膜處理後,從搬入/搬出口 lib移出至 製造裝置外。 201117297 其次,請參照圖2及圖3,圖2及圖3係用以說明成膜腔室na、 之構成、以及於成膜腔室13a、13b所進行的成膜處理。 =圖2所示,成膜腔室13a、13b包含真空槽21,並且真空槽21 U有基板s的基滅物台22以及供給補氣體(六氣化 鶴⑽6)氣體及單矽烧氣體)的原料氣體埠p卜在原&氣體 埠P1下方設置有淋浴頭23 ’肢將频氣料P1所供 均勻地擴散於真空槽21内。 典原料氣體埠P1連結—配管,該配管係分歧成單魏氣體用配 管及六氟化鎢氣體用配管。單矽烷氣體用配管及六氟化鎢氣體 用配管係分別設置有調整氣體流量的流量控制部^^、 MFC3 ϋ控制部、嫌C3_以控織膜處理及潔淨處 理中之氣_流量。上賴潔淨處理储由潔淨氣體之I氣來 去除由於成膜處理而附著於真空槽21内之槽壁或基板載物台22 等構件的鱗薄膜。 用以將惰性軋體之氬(Ar)氣體導入至單石夕烧氣體用配管内的 惰性氣體用配管’係從比私^氣_配管之流量控制部顧^ 還靠近下游湖始分歧。又,用以將惰性氣體之氬氣導入於六 II化嫣氣體舰管⑽惰性氣翻配管,係從比六i化鶴氣體 用配管之流量控制部MFC3翁近下_開始分歧。上述的各惰 性氣體用配管分別設置有流量控制部MFC2、MFC4,以調整氬 氣之流i。流量控制部MFC2、MFC4係用以控制成膜處理及潔 淨處理中之惰性氣體的流量。 於此實施例中’第2惰性氣體供給部係由流量控制部mfc〕及 與其連接的惰性氣體用配管所構成;第丨惰性氣體供給部係由流 量控制部MFC4及與其連接的惰性氣體用配管所構成;單矽烷氣 體供給部係由單矽烷氣體用配管與流量控制部]^(:1所構成;第 201117297 二氣體供f部係由單魏《供給部料2惰減體供給部所 構成’·六氣偏|氣體供給部制讀化鋪_配#與流量控

淨氣體配管_以將潔淨氣體之錄2)氣麟雜氣體之氯氣 同時地供給至真空槽2卜又,潔淨氣體配管設置有流量控制部 MFC5。 真空槽21係透過排氣蟑P3連結渦輪栗(turb〇pump)25。當渴輪 ,25驅動時’真级21之内壓就會被賴至適於成膜處理或潔 淨處理的壓力。真空船、各織體所流通的配管類及基板載 物台22分職置有溫調機構,肋將真空槽21之内壁、配管類 及基板S之溫度維持於預定溫度下。 當基板s經過前處理腔室12a、既之前處理與熱處理腔室14之 熱處理之後,基板S將會被搬運至成膜腔室13&、13b内。然後, 於基板S被載於成膜腔室13a、13b内之基板載物台22的狀態下, 基板S將會藉由設置於基板載物台22的溫調機構加熱至預定溫 度。之後,六氟化鎢氣體及單矽烷氣體從淋浴頭23均勻地擴散 而供給於真空槽21内。下列反應式所示的六氟化鶴之單雜的 還原反應,係在基板S的高導電性部位上進行,亦即選擇性化學 氣相沉積法之成膜。 • 2WP6+3SiH4—2W+3SiF4+3H2,或 201117297 • WF6+2SiH4->W+2SiF3+3H2 需說明的疋’上述基板S之高導電性部位係隨著選擇性化學氣 相沉積法的製造步驟不同而異。舉例而言,當選擇性化學^相 沉積法^形成接觸孔配線時,基板表面係由具有接觸=的絕 緣膜所覆蓋,並且形成於基板表面的M〇s電晶體等之雜質擴散 區域從細孔露a作為絲元件。在輯況下,基板s的高導電 性部位係位於接觸孔之底部的雜質擴散區域,故鎢薄膜係選擇 性地形成於該部位。 '、 另-種情形則是,當選擇性化學氣相沉積法用以形成通孔配 線時,基板表面係由具有通孔的絕緣膜所覆蓋,並且下層配線 的-部分從通孔露出。在此情況下,基板s的高導電性部位係位 於通孔之底部的配線m薄膜顧雜地形成於該部位。 々虽對複數個基板s執行上述細處理時,就可從潔淨氣體用配 管供給氣氣與氬氣於真空槽21,魅高頻電源24會在真空槽21 内產生高頻電場喊行料處理。鱗,瞒於真空槽21之内 壁的鶴薄膜會與使用氟氣的電聚起反應,且生成六氟化鶴、三 氟魏(SiHF3)、四氟魏(SiF4)或氟化氫㈣等的氣化物。然後, 所生成的氟化物會與氬氣一同排出至真空槽21外。 二而透過選擇性化學㈣目沉積法進行成膜處理時,對成膜 腔室1如、13b供給六氟化錢體及單魏氣體賴式,可分 列三種: (A) 同時供給六氟化鶴氣體與單矽烷氣體。 (B) 供給單魏氣體之前先供給六氣體。 (C) 供給六氟化鎢氣體之前先供給單矽烷氣體。 在模式⑷讀況下’⑽產生成贼狀初繼段的核成 且鶴之成膜速度會受到限制。在模式⑼之情況下 ,在比單 201117297

以外’也可能存在於絕緣膜表面上的接觸孔或通孔之周邊。因 此,即使在與所期望之部位不同的其他部位單石夕烧與六氣化鶴 也會起反應,而有形成鎢薄膜之虞。 产於此實_巾’係如模式(Q所示’在細處理職行單魏 氣體之供給處理,並且在單魏氣體之供給處理之後,執行將 存f於成膜腔室13a、13b狀剩餘的單魏、特在於與形成有 鎮薄膜之雜不_其他雜之單魏從成酿室以仙 以去除的排氣處理。

Field of the Invention The present invention relates to a semiconductor device manufacturing apparatus and a semiconductor device manufacturing method, and more particularly to a selectivity for selectively forming a crane film only for a desired position. A device for manufacturing a semiconductor device by a chemical vapor deposition (CVD) method and a method of manufacturing the same. [Prior Art] The constituent elements such as the stone element and the passive element of the Shishi substrate semi-conductive sheet are laminated on the substrate in a state of being sandwiched by the film. In order to electrically connect a plurality of constituent elements, the insulating film is formed with a plurality of through holes to connect the respective constituent elements. In particular, a contact hole is provided between the active element of the substrate and the multilayer wiring laminated on the substrate to electrically connect the active element and the multilayer wiring. Further, the insulating layer is provided with a via structure, and a via hole for electrically connecting the wirings of the respective layers is provided. The contact hole and the through hole are buried with the turn-over:::r:; rr line or the multilayer wiring 2 due to poor interaction between the nucleus (such as parasitic effect), and has high stability to heat «used as a peach line material. (10) The crane has formed a titanium nitride (_, _ with 2 == 』 on the square of the chemical vapor deposition of the bianket (10). The nucleus of the surface layer is shouted 2 201117297 chemical vapor deposition In the method, since the film is a full-faced silk film in the insulating layer, the so-called overhang phenomenon in which the opening area of the contact hole or the opening of the through hole is grown and the opening area is changed. When the overhang occurs, it can be used because it can enter the hemp or the shape of the joint (10) _, so the contact hole or the pass = the buried material is completely used. When the diameter of the turned face is smaller, especially below 疋nm At the same time, the phenomenon that the contact hole or the via hole is buried poorly becomes more conspicuous. Moreover, since the light chemical gas accumulation method requires a fine removal step, the manufacturing steps (4) of the semiconductor device are complicated and the manufacturing cost is also increased. Therefore, in recent years, a selective chemical vapor deposition method which simultaneously simplifies the manufacturing steps and reduces the manufacturing cost (refer to Japanese Patent Laid-Open No. Hei 54), through which the technique can be used only in contact holes or Selective formation of wiring material, such as through holes As a method for forming a fine structure of a crane by selective chemical vapor deposition, it is known that a kind of "complex chamber (10) is given to a similar method. In the middle of the law, 2=) to the mode of supplying the hexafluoride gas and the single-wei gas, it can be divided into the following three types: (A) simultaneously supplying tungsten hexafluoride gas and mono-decane gas. (8) Supplying a single Wei Lai Six crane gas. (C) Supply the Weiwei gas before supplying the hexafluoride gas. Under the mode (8), when the _supply six-cutting body is dissolved, the fine-grained growth will become quite good. The rate is in _ _ _ 嶋, _ _ ^ 2 1. Also 'explicit (8) τ 'mixed supply of Wei Wei gasification Heqi Zhao, and the use of the composition of the semiconductor base (four) gifted _^: = 201117297 == growth, but will be The hexafluoride stands on the surface of the semi-conductor plate, Shi Xi Na II: and causes the surface of the semiconductor substrate to be her. J, =^(C) The lower 乂 is supplied to the single stone 烧 烧 before supplying the SF6 gas. After the supply = reading the anti-ship high in the semi-conductor county, the single Wei molecule reacts with the molecules in the chemical crane gas, so it can promote the existence of the crane. It will exist outside the part where the green line is formed, and the other does not want to work. _Min Department (10).

The limb is uniformly diffused into the vacuum chamber 21 by the tempering material P1. The raw material gas 埠P1 is connected to a pipe, and the pipe is divided into a single Wei gas pipe and a tungsten hexafluoride gas pipe. The piping for the monodecane gas and the piping system for the tungsten hexafluoride gas are respectively provided with a flow rate control unit for adjusting the gas flow rate, a MFC3 control unit, and a gas flow rate for the control of the woven film and the cleaning process. The squamous film of the member such as the groove wall or the substrate stage 22 adhered to the vacuum chamber 21 due to the film formation process is removed by the clean processing of the I gas from the clean gas. The piping for inert gas used to introduce the argon (Ar) gas of the inert rolled body into the single-stone gas-fired piping is branched from the flow control unit of the private gas pipe to the downstream lake. Further, the argon gas for introducing the inert gas into the inert gas distribution pipe of the hexafluoride gas vessel (10) is different from the flow rate control unit MFC3 of the piping for the gas generator of the hexa. The respective inert gas pipes are provided with flow rate control units MFC2 and MFC4, respectively, to adjust the flow i of the argon gas. The flow rate control units MFC2 and MFC4 are for controlling the flow rate of the inert gas in the film forming process and the cleaning process. In this embodiment, the second inert gas supply unit is composed of a flow rate control unit mfc and an inert gas pipe connected thereto, and the second inert gas supply unit is a flow rate control unit MFC4 and an inert gas pipe connected thereto. The monodecane gas supply unit is composed of a monodecane gas pipe and a flow rate control unit, and is composed of a gas supply unit, and the gas supply f unit is composed of a single-wei supply unit 2 inertial reduction body supply unit. The gas supply unit is composed of a flow rate control unit MFC3, and the first gas supply unit is composed of a tungsten hexafluoride gas supply unit disk first inert gas supply unit. The stage 22 is connected to the high-frequency power source 24, and the high-frequency power source 24 is used to apply a high-frequency electric field in the cavity 21, so that the gas guided in the vacuum chamber 21 is plasma-charged by the electric field. A clean orphan body P2 with a rib-guided clean gas is provided. The vacuum chamber 21 is used to alternately perform the film forming treatment and material processing of the (four) material gas. The material gas scale P2 is connected to the clean gas air tube, and the clean gas pipe is provided. _ to record the clean gas 2) The chlorine gas of the gas lining gas is simultaneously supplied to the vacuum tank 2, and the clean gas pipe is provided with the flow rate control unit MFC5. The vacuum chamber 21 is connected to a turbo pump 25 through an exhaust port P3. When the thirsty wheel, 25 drive, the internal pressure of the true level 21 will be relied on the pressure suitable for film formation or cleaning treatment. The vacuum boat, the piping through which the respective bodies are distributed, and the substrate stage 22 are provided with a temperature adjustment mechanism, and the ribs maintain the temperature of the inner wall of the vacuum chamber 21, the piping, and the substrate S at a predetermined temperature. After the substrate s passes through the pretreatment chamber 12a, after the heat treatment of the previous processing and heat treatment chamber 14, the substrate S will be carried into the film forming chambers 13 & 13b. Then, in a state where the substrate S is placed on the substrate stage 22 in the film forming chambers 13a, 13b, the substrate S is heated to a predetermined temperature by a temperature adjusting mechanism provided on the substrate stage 22. Thereafter, the tungsten hexafluoride gas and the monodecane gas are uniformly diffused from the shower head 23 and supplied into the vacuum chamber 21. The single-purity reduction reaction of the hexafluorene crane shown in the following reaction formula is carried out on the highly conductive portion of the substrate S, that is, the film formation by the selective chemical vapor deposition method. • 2WP6+3SiH4—2W+3SiF4+3H2, or 201117297 • WF6+2SiH4->W+2SiF3+3H2 需'The high conductivity of the above substrate S is manufactured by selective chemical vapor deposition The steps vary. For example, when a selective chemical vapor deposition method is used to form a contact hole wiring, the surface of the substrate is covered by an insulating film having a contact =, and an impurity diffusion region of an M〇s transistor or the like formed on the surface of the substrate is fine. Kong Lu a as a wire element. In the case where the highly conductive portion of the substrate s is located in the impurity diffusion region at the bottom of the contact hole, the tungsten thin film is selectively formed at the portion. In the other case, when the selective chemical vapor deposition method is used to form the via wiring, the surface of the substrate is covered by the insulating film having the via holes, and the portion of the lower wiring is exposed from the via holes. In this case, the wiring m of the high-conductivity portion of the substrate s at the bottom of the through-hole is unambiguously formed at the portion. When the above-described fine processing is performed on a plurality of substrates s, the gas and argon gas can be supplied from the clean gas piping to the vacuum chamber 21, and the high-frequency power source 24 generates a high-frequency electric field shouting treatment in the vacuum chamber 21. . The scales and the film of the crucible on the inner wall of the vacuum chamber 21 react with the electricity using fluorine gas to form a vaporized product of hexafluoride, trifluoro-Wei (SiHF3), tetrafluoro-Wei (SiF4) or hydrogen fluoride (IV). . Then, the generated fluoride is discharged to the outside of the vacuum chamber 21 together with the argon gas. 2. When the film formation process is carried out by the selective chemical (four) mesh deposition method, the hexafluoride and the monowei gas Lai can be supplied to the film forming chambers 1 and 13b, and three types can be classified: (A) hexafluoride is simultaneously supplied. Chemical crane gas and monodecane gas. (B) Supply six gases before supplying the Wei gas. (C) The monodecane gas is supplied before the supply of the tungsten hexafluoride gas. Under the mode (4) reading, '(10) produces a nucleus-like initial segment and the filming speed of the crane is limited. In the case of mode (9), the hexafluoride _ located on the surface (4) of the substrate, which is supplied earlier than the single 201117297 gas, will perform the following reaction. Although the speed of the county is improved, the surface of the substrate will be Being eroded. • 2WF6+3Si-^2W+3SiF4 In the case of mode (C), before the supply of the hexafluoride gas, the gas is adsorbed on the substrate, and the single-wei molecule is supplied later. The molecular reaction of hexafluoride. Therefore, the speed of growth can be improved. The thinness "may be present in the vicinity of the contact hole or the via hole on the surface of the insulating film due to the fact that the single Wei gas acts in addition to the contact hole or the via hole." Therefore, even in the other parts different from the desired part, the single stone and the six gasified crane will react, and there is a flaw in the formation of the tungsten film. The production is based on the mode (Q shows 'in the processing of the fine processing of the single-wei gas supply, and after the supply treatment of the single Wei gas, the execution will be stored in the film forming chambers 13a, 13b The remaining single Wei is specially treated with the exhaust gas formed by the formation of the film of the town, and the exhaust gas is removed from the brewing chamber. The film forming chamber 133 is described with reference to FIGS. 3 and 4 . The execution timing of the single-stone gas supply processing, the exhaust gas treatment, and the processing performed by 13b, and the processing conditions of the processing, etc., Fig. 3 is a single-institution gas supply that is not performed in the film forming chamber, for example, 13b. In the processing, the exhaust gas treatment, and the supply period of the various gases during the film formation process, Fig. 3 (8) '3 (eH shows the single stone gas (leg 4) and the supply to the single Wei gas pipe (Ar) Gas, six-figure gas (Wp6), supply cliff _ read 赖 ^ = partial pressure of oxygen. As shown in Figure 3, during the period from time Guo to t2, within the vacuum tank from the single stone eve 12 201117297 The gas-fired π-pipe supplies the single-stone gas and the argon gas from the hexafluoride gas gas piping. The stagnation gas system is adsorbed on the highly conductive part of the substrate s, and also exists in other hiding. In the single Wei gas ship, the gas can be burned in a single stone, and the slave is 5.9xl 〇 3Pam3/ s (version em), the flow rate of argon gas is set to ll.8xl03Pam3/s (2〇sccm), and the internal pressure of vacuum chamber μ is set to (10), and is maintained for 15 seconds, but not limited thereto. Thereafter, during the period from the time t2 to the time t3, argon gas is supplied from the single-stone gas-fired piping, and argon gas is also supplied from the six-t/iui gas ship f.

Thereafter, during the period from _3 to the phase, the Weiwei gas and the hexafluoride crane are The gas is supplied to the true miscellaneous 21. By this, the contact hole or the through hole of the sacrificial substrate is selectively formed to selectively form a crane film. The flow of the six gasified Wei body can be turned to pure on the two sides. The 3pam3/s (2Qs_) is maintained, the flow rate of the grass stone is maintained at 5.9xl〇3Pam3/s (1〇sccm), and the vacuum chamber j is pressed. While maintaining the pressure of the hexafluoride hexafluoride in the film forming chambers 13a and 13b to be higher than the partial pressure of the monofilament gas, the gas is supplied to the vacuum chamber 21 while maintaining the a4pa' side. However, it is not limited to this. The issuance of the sun-like shape is performed on the day_to-time sequence only when the single-stone supply processing is performed under the above conditions and the exhaust processing is performed during the timing t2 to the time t3. Membrane nm/min is formed selectively. _, as long as it is suitably selected as a break, the thickness _ film can be selectively obtained. In the case of the series-type treatment, the reaction product other than tungsten or the various components of the gas component represented by the chemical formula of the so-called SiHxFy, such as the three gas stone garden (Lion 3) and the gas stone, 13 201117297 (4) The adsorption, so the temperature can be used to add age and the difference between the two, then the temperature of the sputum or the supply of various gases is maintained at 8 (rc. In addition, the county can be heated by the temperature to build the substrate The port 22 is maintained at the temperature of the substrate s to be placed on the substrate stage 22. Next, the reference 4 says that the single-wei gas supply treatment performed by the fine-treated surface and the touch-up Weipu Figure 4 shows the effect of the favorable supply time of the gas and the beneficial treatment of the exhaust gas treatment on the selectivity of the film formation process.

In addition, 'the treatment of single stone smoldering gas before the film formation process for 5 seconds, the selectivity; the trace is 10_like and unmade __. In order to go to Weiwei _ _ _ _ _ _ _ Wei gas supply, selective cracks are more than 10 and less than _ solid. In addition, and in the nature of the material Qianna coffee 5 secret, choose this 'as long as the single stone gas burning gas supply before the film formation process Treatment, 14 201117297 After the exhaust treatment is performed, the supply of the selective cracked filaments can be treated to the same extent. Also, in the case of a single stone, the second =:: Shi Xi = when the piece is _, for example, by After performing the exhaust treatment of the single-wei gas single-stone soaking body supply treatment, it is possible to suppress μ, and the trace suppression is about 1/1000. According to the present embodiment, the following effects can be obtained: (1) by supplying the film in the process of processing the single-wei gas supply treatment and gas treatment, it can be adsorbed on the fine conductive portion. The tungsten hexafluoride gas starts from the ^ ^ and the film forming center, and the non-absorbed _ substrate s guides the exhaust gas from the film forming chambers 13a, 13b, and the unexposed bismuth is present in the conductivity. The insulating layer of the higher part is formed on the substrate 8, and only the Hetao film can be formed in the portion with high conductivity, and the rotation can be suppressed by the treatment: the film formed by the film is selectively formed in the film. Expected = If it is in the vacuum chamber (4), the condition of partial pressure and partial pressure of hexafluoride gas is 1), which is more remarkable.) Supply argon.

In addition, it can be fully confirmed that the argon gas treated by Wei is 2) even if it is in the argon supply unit of the Weiwei gas piping, it can be normal. The argon supply unit supplies argon gas. Therefore, it is possible to provide a manufacturing apparatus of a semiconductor device which is highly reliable and highly reliable. W is in the early Wei gas supply process, in the vacuum gas and inert gas. At this time, in the absence of J supply,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, Therefore, the Wei gas and the domain hexafluoride gas are reacted in a pipe, and the reaction product is adsorbed to the gas of the six coffees. When the film is formed, there will be a time from the hexafluoride gas to the gas.
