A7 31C445 B7 五、發明説明(1 ) 〔產業上之利用領域〕 本發明,係有關在眞空下爲了對被處理體進行成膜及 蝕刻等處理用的眞空處理裝置, (請先聞讀背面之注ί項再填寫本頁) 〔習知技藝〕 在半導體晶片製造工程,做爲在半導體晶片之表面形 成絕緣膜或矽的薄膜之薄膜形成裝置,已在使用頁紙式 CVD裝置。如此的頁紙式CVD裝置,具有在眞空環境 進行成膜用之氣密的處理室,在其中設有保持晶片用之載 置台。然後,在該載置台上面,設有利用靜電力將半導體 晶片吸著用的靜電夾。 如此之靜電夾,具有將薄的導電體之上下面以絕緣層 挾住的構造,將根據在上述導電體施加直流電壓時所發生 之庫侖力或强生一拉別克(J 〇 h n s e n R a h b e c k )力把晶片 吸著保持。 經濟部中央樣準局員工消費合作社印製 可是,在C V D裝置,以確保成膜的均匀性之意義而 要求被處理體的面內均勻性,亦即,將要求在面內之溫度 分佈的均匀性。因此,習知者,係在上述處理室內設有將 被處理體加熱爲適當溫度用之加熱裝置。做爲該加熱裝置 ,係使用在上述靜電夾的下面側,配置在和靜電夾隔離之 位置,使加熱裝置的發熱體之熱會根據輻射而傳達到上側| 的靜電夾者。 然而,如此地把靜電夾和加熱裝置隔離設置*根據加 熱裝置之輻射熱把靜電夾上的晶片加熱時’將會產生如下 本紙乐尺度適用中國國家標率(CNS ) Α4规格(210Χ297公釐> ^10445 a? Β7 經濟部中央樣準局員工消費合作杜印裂 五、發明説明(2 ) 之問題。 首先,因爲把從加熱裝置的熱根據輻射使之傅達,所 以傳達效率不太佳。而且,通常此種載置台,係設在例如 設定成1 0 ^To r r的眞空環境之氣密的處理室內,所 以設置在處理室內時熱傳達率將會更降低,所以不得不把 加熱裝置設置在處理室外部之大氣中。 同時,做爲改善傳達效率者,有在被處理體的載置面 ,例如,根據螺旋狀之發熱電阻體加熱者。然而,此時由 於發熱體接近做爲被處理體的半導體晶片,所以發熱體之 配置圖型的影響將會直接出現在晶片上,由於據此之溫度 分佈的不均匀,而有無法進行均勻處理之問題。在上述 CVD裝置,如果發生如此的溫度分佈之不均勻時,將不 能形成均匀的膜。 並且,因使裝載靜電夾之載置台和加熱裝置成爲各別 者,所以構件數多而裝配時間也長,隨之成本也高。 可是,在頁紙式CVD裝置,需要在被處理體的半導 | 體晶片上使薄膜均勻地成長,因此將要求在半導體晶片之 表面全體把反應性處理氣體均勻地供給。因此,自先前, 爲了把反應性處理氣體均勻地供給到半導髏晶片的表面全: 體,把在氣體吹出面有多數之孔以均勻的間隔穿孔之蓮蓬 頭設在處理室的頂部。 根據習知之蓮蓬頭,把處理氣體從其蓮蓬頭的對向於 被處理體之面全體均勻地吹出時,處理氣體的流置將有從 被處理體之中央部向端部增加的傾向。因此,處理氣體之 (請先M讀背面之注意事項再填寫本f 裝-- τ ,va ------if----J——k------ 本紙張尺度適用中國國家樣準(CNS > A4规格(2丨0X297公釐} ........*....................11111·ι"·ι"ιι·ιι III μι ιι ||Ι· IIVI ·- 經濟部中央標準局員工消費合作杜印製 310445 a7 _____ B7 五、發明説明(3 ) 漉度境界層的厚度將會愈靠近半導體晶片之中央部愈厚, 而愈靠近端部愈薄。結果,即使從蓮蓬頭的氣體吹出面將 處理氣體均勻地供給到處理室内,也不--定能使處理氣體 以均勻之澳度分佈在半導體晶片的反應表面,因此,有成 膜率將會變成不均匀之處。 一方面,在靜電夾將需要從高壓電源的給電,同時, 在把被處理體加熱用之發熱體將需要大電力,所謂,從能 旋加高電流的電源之給電,但是,C. V D製膜裝置,係如 上述,以眞空環境進行處理,所以將容易在導電體間發生 放電。而且,從接近加熱器處的配線露出部,有時會根據 金饜蒸氣之發生而產生對被處理體的重金靨污染。因此, 不得不在大氣中進行配線。所以,因爲配線將需要和眞空 環境之遮斷構造,故其構造將變成複雜。而且,遮斷構造 將會接觸被處理髄的加熱溫度璣境,而有無法維持耐久性 之虞。因此,不只是遮斷構造將變爲複雜,同時需要如此 的構造之份成本將會增加。 〔發明之概要〕 本發明之目的,係在提供從加熱裝置之熱傳達效率高 ,提高半導體晶片等被處理體的均熱性之眞,空處理裝置。 本發明之其他目的,係提供在保持眞空中之處理室內 ,能夠進行靜電夾和加熱器的給電用配線之眞空處理裝置 0 本發明之更其他目的,係提供在如此之眞空處理裝® 本紙張尺度適用中國國家揉準(CNS ) A4规格(2丨0 X 297公1 ) (請先聞讀背面之注意事項再填寫本頁) 裝- 訂 31C445 A 7 B7 五、發明説明(4 ) 所使用的,具有靜電夾及加熱機能之被處理體的載置台。 根據本發明之第1觀點時,將提供具有在眞空下進行 處理被處理體的處理室; 和設在前述處理室內,有載置前述被處理體用的載置 面之載e構件: 和設在前述載置構件的載置面,使前述被處理體吸著 用之靜電吸著裝置: 和將前述被處理體加熱用的加熱裝置: 和對前述處理室供給將被處理體處理用的處理氣體之 處理氣體供給裝置; 前述載e構件,但具有基材,和形成在該基材表面的 第1絕綠層,和設在第1絕緣層上之第2絕緣層, 在前述載置構件的前述載置面側的第1絕緣層和第2 絕緣層之間具有導電層,根據前述第1絕綠層,和前述第 2絕緣層,與前述導電層構成前述靜電吸著裝置’ 前述加熱裝置,係具有在和前述載置構件的載置面相 反側之面側的第1絕緣層與第2絕緣層之間所設的加熱體 之眞空處理裝置。 根據本發明之第2觀點,將提供具有,將在眞空下進 行處理被處理體的處理室; 和設在前述處理室內,有載置前述被處理體用的載置 面之載置構件: 和設在前述載置構件的載置面,爲了使前述被處理髏 吸著用之靜電吸著裝置: 太紙張尺度適用中國國家標準(CNS ) A4规格(21(Γχ 297公|ίΤ (讀先聞讀背面之注意事項再填寫本頁 1 裝 、-=* 經濟部中央標準局員工消費合作社印製 A7 S1C445 __B? _ 五、發明説明(5 ) 和爲了將被處理體加熱用之加熱裝置: (請先閲讀背面之注意事項再填寫本頁) 和對前述處理室供給處理被處理體用的處理氣體之處 理氣體供給裝置: 前述載置構件,係具有絕綠性的基材,和形成在該基 材表面之絕緣層, 在前述載置構件的前述載置面側之基材和絕綠屠之間 有導電層,根據前述基材和前述絕緣層,和前述導電層構 成前述靜電吸著裝置, 前述加熱裝置,具有設在和前述載置構件的載置面相 反側之面側的基材與絕緣層之間的加熱體之眞空處理裝置 0 根據本發明之第3觀點時*將提供具有,在眞空下進 行處理被處理體的處理室; 和設在前述處理室內,有載置前述被處理髋用的載置 面之載置構件: 和爲了將前述被處理體加熱用的加熱裝置: 經濟部中央標隼局員工消費合作杜印聚 和對前述處理室供給處理被皰理體用的處理氣體之處 理氣體供給裝置; 前述載置構件,但具有基材,和形成在該基材表面的 絕緣層, 前述加熱裝置,具有在和前述載置構件的基材之載置 面相反側之面以所定間隔所設的螺旋狀或同心狀之加熱體 前述基材的厚度,係設定爲比前述加熱體之間隔大的 東紙張尺度適用中國國家標準(CNS ) A4胡潘(2丨0乂297公系) —- 經濟部中央橾準局員工消费合作社印装 A 7 B7 五、發明説明(6 ) ~~ 眞空處理裝置。 根據本發明之第4觀點時,將提供具有在眞空下進行 處理被處理體的處理室: 和設在前述處理室內,有爲了載置前述被處理體用的 載置面之載置構件; 和爲了加熱前述被處理體用的加熱裝®: 和對前述處理室供給處理被處理體用之處理氣體的處 理氣體供給裝置; 前述加熱裝置,係具有設在和前述載置構件的載置面 相反側之面的中央加熱體,和前述載置構件側部之側部加 熱體的眞空處理裝置。 根據本發明之第5觀點時,將提供具有在眞空下進行 處理被處理體的處理室: 和設在前述處理室內,有爲了載置前述被處理體用之 載置面的載置構件; 和設在前述載置構件的載置面,爲了使前述被處理體 吸著用之靜電吸著裝置: 和對前述處理室供給處理被處理體用之處理氣雠的處 理氣體供給裝置: 前述靜電吸著裝置,有將施加高電之電極;和介裝 在電極與被處理體之間的絕緣層: 前述絕緣層,係在前述被處理體之處理中體積電阻係 數1 0 6〜1 0 1 2 Ω . c m,其吸著面的表面粗縫度R a 爲Ο . 2〜3 . l"m之眞空處理裝置° 木紙張尺度適用中國國家揉準(CNS ) A4规格(210X297公釐) (請先聞讀背面之注意事呼再填寫本頁) 裝· 訂 310445 at _ B7 五、發明説明(7 ) 根據本發明之第6觀點時,將提供具有在眞空下進行 處理被處理體的處理室; 和設在前述處理室內,有爲了載置前述被處理體用的 載置面之載置構件: 和爲了將前述被處理體加熱用的加熱裝置: 和爲了控制前述加熱裝置用之控制裝置: 和對前述處理室供給了爲了處理前述被處理體用的處 理氣體之處理氣體供給裝置: 前述加熱裝置,係使之有對應於形成在前述載置構件 的載e面成同心狀之多數領域地,設在前述載置構件的多 數加熱體, 前述控制裝置將各別地控制此等加熱體之輸出,的眞 空處理裝置。 根據本發明之第7觀點時,將提供具有在眞空下進行 處理被處理體的處理室: 和設在前述處理室內,有載置前述被處理體用的載置 面之載置構件; 經濟部中央橾準局員工消費合作社印製 (請先聞讀背面之注意事項再填寫本頁) 和將前述被處理體加熱用的加熱裝® : 和對前述處理室供給處理被處理體用之處理氣體的處 理氣體供給裝置; 和控制從處理氣體供給裝置Z處理氣體供給量用的控 制裝置: 前述處理氣體供給裝置,係設成對向於前述被處理體 ,有區畫成同心狀的多數氣體吐出領域之處理氣讎導入構 ~~~·' . 本紙张尺度適用中國國家梯率(CNS )六4規格(2丨0X297公* ) - 10 - --................ . ................. ................................ ..ww«-靜 . 經濟部中央標準局員工消費合作社印製 A7 B7 五、發明説明(8 ) 件, 前述控制裝置,將各別地控制從各領域的氣體吐出量 之眞空處理裝置。 根據本發明之第8觀點時,將提供具有在眞空下進行 處理被處理體的處理室; 和設在前述處理室內,有載置前述被處理體用之載置 面的載置構件; 和在處理被處理體時將被供給電力之被給電部: 和具有底開口部,和設在其基端側的接點,和形成在 其開口端側之絕緣被覆,將電性地連接在前述被給電部的 插座端子: 和能壓入到該插座端子,而在壓入時將接觸在前述接 點之插頭端子: 的眞空處理裝置。 根據本發明之第9觀點時*將提供具有載置被處理體 用的載置面之載置構件: 和設在前述載置構件的載置面,使前述被處理體吸著 用的靜電吸著裝置; 和爲了將前述被處理體加熱用之加熱裝置; 前述載置構件,有基材,和形成在該基材表面的第1 絕緣層,和設在第1絕緣層上之第2絕緣層, 在前述載置構件的前述載置面側的第1絕綠層和第2 絕緣層之間有導電層,根據前述第1絕緣層,和前述第2 絕緣層,與前述導電層構成前述靜電吸著裝置, 象紙張尺度適用中國國家棵準(CNS 規格(210X297公:缓) η ----ΓF — Λ 裝!

Description of the invention (1) [Industrial application field] The present invention relates to a void processing device for filming and etching of the object to be processed under the void, (please read the back page first Note ί item and then fill out this page) [Conventional Techniques] In the semiconductor wafer manufacturing process, as a thin film forming device for forming an insulating film or a silicon thin film on the surface of a semiconductor wafer, a sheet-type CVD device has been used. Such a sheet-type CVD apparatus has an airtight processing chamber for film formation in a void environment, and a stage for holding wafers is provided therein. Then, an electrostatic clamp for attracting the semiconductor wafer by electrostatic force is provided on the top of the mounting table. Such an electrostatic clamp has a structure that encloses a thin conductor above and below it with an insulating layer, and it will be based on the Coulomb force or the Johnson-Rabeck force that occurs when a DC voltage is applied to the above conductor Hold the wafer by suction. Printed by the Employees ’Consumer Cooperative of the Central Bureau of Samples of the Ministry of Economic Affairs. However, in order to ensure the uniformity of the film formation in the CVD device, the in-plane uniformity of the processed body is required, that is, the uniform temperature distribution in the surface Sex. Therefore, those skilled in the art are provided with a heating device for heating the object to be processed to an appropriate temperature in the processing chamber. As the heating device, it is used on the lower side of the electrostatic clip, and is arranged at a position separated from the electrostatic clip, so that the heat of the heating element of the heating device will be transmitted to the upper side of the electrostatic clip according to the radiation. However, in this way, the electrostatic clip and the heating device are isolated. When the wafer on the electrostatic clip is heated according to the radiant heat of the heating device, the following paper music standards will be applied to the Chinese national standard (CNS) Α4 specification (210Χ297 mm) ^ 10445 a? Β7 Ministry of Economic Affairs Central Sample Bureau Employee Consumer Cooperation Du Yin crack 5. Invention description (2) The problem. First, because the heat from the heating device is made up by radiation, so the transmission efficiency is not good. Moreover, usually such a mounting table is installed in an airtight processing chamber set to an empty environment such as 10 ^ To rr, so the heat transfer rate will be lowered when installed in the processing chamber, so the heating device has to be installed In the atmosphere outside the processing chamber. At the same time, as a means of improving the transmission efficiency, there is a mounting surface on the body to be processed, for example, a heater based on a spiral heating resistor. However, at this time, due to the proximity of the heating element The semiconductor wafer of the processing body, so the influence of the layout pattern of the heating body will appear directly on the wafer. Due to the uneven temperature distribution according to this, there is no way The problem of uniform treatment. In the above CVD device, if such uneven temperature distribution occurs, a uniform film cannot be formed. Moreover, since the mounting table and the heating device on which the electrostatic clip is mounted are separate, the number of components It takes much time to assemble and the cost is also high. However, in the sheet-type CVD apparatus, it is necessary to uniformly grow the thin film on the semiconductor wafer of the object to be processed, so it will require the entire surface of the semiconductor wafer The reactive processing gas is uniformly supplied. Therefore, in order to uniformly supply the reactive processing gas to the entire surface of the semiconductor wafer, the shower head with a large number of holes perforated on the gas blowing surface at even intervals is provided. At the top of the processing chamber. According to the conventional shower head, when the processing gas is evenly blown out from the face of the shower head to the surface of the body to be processed, the flow of processing gas will increase from the center to the end of the body to be processed The tendency is to deal with the gas. (Please read the precautions on the back first before filling in this f pack-τ, va ------ if ---- J ---- k ------ This paper scale Applicable to China National Standard (CNS & A4 specifications (2 丨 0X297mm) ........ * ................... 11111 · ι " · Ι " ιι · ιι III μι ιι || Ι · IIVI ·-Ministry of Economic Affairs Central Standards Bureau employee consumption cooperation du printing 310445 a7 _____ B7 V. Description of invention (3) The thickness of the boundary layer will be closer to the semiconductor The thicker the central part of the wafer, and the thinner the closer to the end. As a result, even if the processing gas is evenly supplied into the processing chamber from the gas blowing surface of the shower head, it will not be able to distribute the processing gas in a uniform degree. The reaction surface of the semiconductor wafer, therefore, has a film formation rate that will become uneven. On the one hand, the electrostatic clip will require power supply from a high-voltage power supply, and at the same time, the heating element for heating the body to be processed will require large power, so-called, power supply from a power supply capable of rotating high current, but, C. VD system The membrane device is treated in a void environment as described above, so discharge will easily occur between conductors. Furthermore, from the exposed portion of the wiring close to the heater, heavy gold contamination of the object to be treated may occur due to the occurrence of gold vapor. Therefore, wiring has to be performed in the atmosphere. Therefore, since the wiring will require an interruption structure to the empty environment, its structure will become complicated.

The invention description (15) The material 22 is directly transferred to the wafer W by contact, so the heat transfer efficiency is higher than that of conventional radiation by radiation, and as a result, the wafer W can be heated to the same temperature with lower power than the conventional one. Furthermore, as described above, the thickness (height) D of the base material 22 is set to be larger than the interval d of the heating element 2 6 a of the heater 26, so that the spiral heating skull 2 6a will not be formed. The pattern affects the wafer W, and the wafer W can be heated uniformly. Therefore, the wafer W can be subjected to a uniform film formation process. Furthermore, because the heater 26 is incorporated into the mounting table 21 and integrated, the number of components can be reduced compared to the previous one, and the entire heating mechanism can be installed in the processing chamber 2 at the same time. Therefore, the assembly is also easy, which complements the above-mentioned reduction in the number of components, and will reduce costs. The first insulating layer 2 3 and the second insulating layer 2 7 formed on the outside of the mounting table 2 1 are both formed by the CVD process, so their thicknesses are extremely uniform, and the thermal uniformity of the wafer W is also high according to this point . As its material, when using P — BN, S i 〇2, A 1 N, A 2 〇3 or S i N, etc., the heat resistance is excellent, so the heater 26 is set to be directly attached, There is no obstacle to heat.

By making it into such a structure, durability will become stronger. At the same time, in order to make the temperature of the wafer W uniform and to control the temperature more precisely, for example, a circulation path of a cooling medium may be formed in the substrate 22 in the mounting table 21. However, the electrostatic clip S, as described above, will attract the wafer w according to the Coulomb force or Johnson-Rabe force. Then, the resistivity of the first insulating layer 23 is about 1 () 1 4 The electrostatic attraction force according to the Coulomb force will occur above Ω. Cm, and the electrostatic attraction force according to Johnson-Rabek force will occur below approximately 1 0 1 4 Ω · cm. Here, the Jingle clip based on Johnson & Labek will be described with reference to FIG. 7. As shown in the figure, on the surface of the green layer 1 and the mounting surface of the semiconductor wafer W mounted thereon, there are irregularities on the microscopic view, and it can be considered that the contact portion and the non-contact between the two are randomly present ° Here, when the volume resistivity of the insulating layer 1 is less than 1014 Ω.cm and not too large, when the current i is applied to the wafer W through the insulating calendar 1, the contact between the green layer 1 and the semiconductor wafer 1 The point will be locally generated due to the contact resistance R c. • A large potential drop will exist on the part with extremely small gaps on both sides, and # will be on the opposing surface of the insulation 1 body 1 and the wafer w (forming a capacitor ) Accumulation of positive and negative charges 1 generates an extremely high electric field, and the result of the strong Maxwell's variable force will produce electrical attraction. Such an effect is called the Johnson-Rabek effect, and the electrical attraction generated at this time is called Johnson-Rabek. This Johnson-Rabe force is shown schematically in Fig. 8 as a function of the potential decrease V / caused by the contact resistance R c.

Description of the invention (17) Here, when the applied voltage is v, the volume resistivity of the insulating layer is Rs, the distance between the wafer and the insulating layer is d β, and the distance between the wafer and the electrode is d, the above potential decreases by V — It will be expressed as V- = V-Rc / (RC + Rs) and under Johnson & Johnson Laplacian it will be expressed as * F two (1/8 a) · (V-/ d ^) 2 Figure 9, the system will oxidize Aluminum mirror processing sample B, directly cut sample 2, and rough surface processed sample 3 are used as insulating layers. By changing these temperatures, the volume resistivity changes, and the electrostatic force at this time is marked as According to the graph, the electrostatic force is small when the volume resistivity is more than 1 0 1 4 Ω · c til, but the electrostatic force will become larger when it is less than 1 Q 1 1 Ω · cm. This is based on the following Reason: When the volume resistivity of the insulating layer is 1 014Ω · cm or more, the volume resistivity Rs and In the series resistance formed by the contact resistance R c, the value of V > will become smaller due to the dominance of R s, and therefore the electrostatic force will become smaller. In contrast, when it is less than 1 0 1 1 Ω · C m The RC will dominate the fan and the electrostatic force will increase. Then, in these intermediate areas, the electrostatic force will be opposed, so the electrostatic force will become an intermediate value. In general, insulators such as ceramics are known to increase their temperature when the temperature rises. The coefficient of resistance will decrease exponentially. For example, when a thermal device such as a cvd device is to heat the semiconductor wafer w of the object to be processed according to the force α, the temperature of the insulator (please read the notice on the back before filling in this page) -The size of the bundled paper is applicable to the Chinese National Standard (CNS) Α4 specification (210Χ 297 mm). 20 Printed by the Employee Consumer Cooperative of the Central Prototype Bureau of the Ministry of Economic Affairs. The resistance coefficient will inevitably decrease. Therefore, when the body resistance coefficient becomes 1 · cm or less according to the temperature rise, as shown in FIG. 9, the electrostatic force according to Johnson-Labeli will increase, and the insulation layer And leakage May rise, and there is a risk of damaging the semiconductor circuit formed on the wafer. In this way, when the resistivity of the volume is low, "In order to reduce the leakage current, it is only necessary to increase the R c, so for this reason, the surface roughness of the insulating layer needs to be changed. It can be as large as possible. That is, in order to reduce leakage, it is only necessary to increase the surface roughness of the insulating layer. Figure 10 is used as an insulating layer with a volume resistivity of 1 0 1 1 Ω • cm or less S i C (thickness 1 mm, surface roughness R a: 0 · 2 4 and 0 · 9 0), the value of the leakage current when the applied voltage V is changed at normal temperature in the state shown in FIG. 8. As shown in this figure, it can be seen that when the surface roughness Ra is rough, the leakage current becomes small. On the one hand, as shown in Fig. 11, it can be seen that the surface roughness of the suction system will increase when the surface roughness is small. In this way, the leakage current and the electrostatic attraction force (electrostatic force) are opposite, so when the volume resistivity of the insulating layer is low, the surface thickness of the insulating layer needs to be roughened, while having an appropriate attraction force to reduce the leakage current The value. Specifically, when the volume resistivity of the insulating layer is 1 0 6 ~ 1 〇12 Ω · cm, the surface roughness Ra of the insulating layer is adjusted within the range of 0 · 2 ~ 3 · 1 (unit: " m) And, it can have a moderate suction force and make the leakage less.

The following description of the second form of the present invention 〇 About this form The structure of the CVD apparatus is the same as the first form except for the mounting table. Figure 1 2 shows the cross section of the military platform used in this form. The mounting table 6 0 f is made of boron nitride (BN), for example. It is said that the mounting surface 6 0 A for forming the semiconducting SUh body wafer W on which the object to be processed is formed is formed on the mounting surface 6 0 A. The same static electricity as the first form is placed on the mounting surface 6 0 A According to this, the semiconductor wafer W is electrostatically attracted and held by the clip.

Description of Invention (2〇) The bottom plate 9 is constructed in the same way as the device of the first form. The space 6 0 C surrounded by the bottom plate 9 and the foot 6 Ο B is to maintain the exhaust mechanism according to an unillustrated state in a vacant state. Therefore, the area where the mounting table 60 and the bottom plate 9 are in contact is, of course, shown below that the lower surface of the mounting table 60 is all in contact with the lower mounting table. A central heating body 6 4 is provided below the placing table 60, and a side heating body 6 6 is provided on the outer side. The central heating body 64 and the side heating body 6 6 are made of conductive heating resistors. Then, the central heating body 6 4 * is the portion opposite the mounting surface 6 0 and the mounting surface 6 [) A, that is, on the top surface of the cavity portion 60, so that the semiconductor wafer w can be Heating size setting. At the same time, the side heating element 6 6 is provided on the upper surface of the mounting table 60 corresponding to the area around the mounting surface 6 OA and the side surface of the mounting table 60. Therefore, the mounting table 60 is provided with a heating source in almost all areas other than the mounting surface f] 〇a on the surface. In addition, in the figure, there is also a heating body on the inner side of the foot 6 OB, but it is not necessary to install a heating body in this part. In this system, since the space 60 ° C maintains the vacant state and becomes the so-called vacant thermal insulation state, there is not much heat dissipation to the inside. Therefore, what is necessary as a heating source provided at the foot 6 OB is from the outer side where the heat release from the mounting table 6 Q is remarkable. At the same time, in areas other than the mounting surface 6 Ο A above the mounting table 60, it is desirable to provide a heating body 6 6.

Description of invention (21). At this time, since the wafer W will be heated across the stage, it will substantially prevent the heating pattern of the heating body from appearing on the wafer mounting surface 6 Ο A. Therefore, the heating pattern of the heating body will not be transferred to the back of the wafer as the object to be processed. In addition, the outer periphery of the mounting table 60 is green, and will be heated by the side heating body 66, so-called heat supplement will be performed, so that heat dissipation is suppressed, and the temperature distribution uniformity is maintained on the surface of the mounting table 60. -In the aspect, the foot 6 Ο B is provided under the mounting table 60, and the heating body is provided on the outer side or the inner side, so it can reduce the contact heat transfer part and suppress the heat loss due to the heat, and, due to the foot Part 6 Ο B has a certain length, so it will prevent the heat retention from decreasing sharply. According to this, it is possible to prevent the temperature distribution on the mounting surface from changing. That is, if the distance from the foot 6 Ο B to the heat dissipation part is shorter, the distance to the heat dissipation position is increased, and the heat dissipation up to the position is heated to supplement the heat dissipation position. The lowering of the temperature, in other words, can make the temperature gradient become gentle. Therefore, the influence on the heat dissipation of the mounting surface can be reduced, and the change of the temperature distribution on the mounting surface can be reduced. Moreover, by slowing down such temperature changes, the temperature change part can also be removed to prevent thermal damage to the machine. In other words, a temperature sensor 68 for controlling the energization of the heating body is provided on the mounting table 6 Q as indicated by circle 13A. Figure! 3 a is a schematic diagram showing the installation state of the temperature sensor in the central part of the mounting table 60. In the same figure, the temperature sensor 6 8 is, for example, a thermocouple arranged in a quartz tube. structure. Such a temperature sensor 6 8 is also arranged at a position other than the center of the mounting table 6 Q as described later. The Chinese National Standard (CNS) A4 standard is applied to the size of the mounted paper (2 丨 〇: < 297 公 嫠 i — (please read the precautions on the back and then fill out the grate). Installation and ordering-3 ^ C445 Central Ministry of Economic Affairs Printed by the Bureau of Standards and Staff's Consumer Cooperatives A 7 B7 V. Description of invention (22) The installation part of the temperature sensor 6 8 of the station 60, if there is a simple part 6 OD protruding from below, the head of the temperature sensor 6 8 The part will be inserted into the barrel part 6 OD and support the temperature sensor 68. Normally, the temperature sensor 6 8 is inserted as shown in FIG. 1 3B so that the head is close to the mounting surface 6 0 Α, but According to this installation structure, the heat on the mounting surface 6 Ο A will be easily dissipated according to the heat transfer of the temperature sensor 68. Therefore, in the surface of the mounting surface 60 A, the temperature sensor will The temperature at the location will decrease, and the temperature distribution in the surface will change. Moreover, it will also become the temperature sensor itself and the temperature at the head will be different from the mounting surface, and it will become impossible to detect correctly Temperature. Therefore, in this case, it is due to the support of the head of the temperature sensor 6 8 The position of the barrel portion 6 0 D is based on the supply of heat that can supplement the heat dissipation by the heat according to the barrel portion 60 D. Therefore, the head of the temperature portion 6 8 is supported by the crown portion 6 0 D as The function of the supporter can also compensate for the heat loss due to the heat transfer of the temperature sensor 6 8 to prevent the heat on the mounting surface from being taken away. Therefore, it will prevent the temperature distribution on the mounting surface 6 OA from changing, At the same time, it is possible to prevent an error between the mounting surface temperature and the detected temperature caused by the temperature drop of the temperature sensor itself. The temperature sensor 6 8 is provided in many places along the direction of the wafer W to monitor the object to be processed. The temperature in the whole range is ideal. However, in order to prevent the temperature distribution of the mounting surface 6 Ο Α of the mounting table 6 〇 from being changed by the temperature sensor 68 due to heat conduction, it becomes the necessary minimum number, for example, in As shown in Fig. 14 described later, the two parts near the central part and the outer periphery of the adult wafer W are ideal.

Invention description (26) These heating bodies are made. In the example shown in the figure, three heaters 1 1 6, 1 1 7, 1 1 8 are arranged in a slightly concentric pattern, but (please read the precautions on the back and fill in this page) It is not limited to such a configuration, but an arbitrary number of heating bodies can be mounted on the mounting table with an arbitrary design, and many desired fields on the surface of the mounting table can be independently heated and kept warm at desired temperatures. At the same time, as shown in FIG. 19, the mounting table 1 〇9 is formed with three concentric circular heating areas 1 2 3, 1 2 corresponding to the heating bodies 1 1 6, 1 1 7, 1 1 8 4, 1 2 5, temperature sensors 1 5 2, 1 5 3, 1 5 4 are installed in these heating areas respectively. From these temperature detectors 1 5 2, 1 5 3, 1 5 4 detection signals will be input to the above controller 1 1 9, according to the girdle detection signal, the controller 1 1 9 anti-hunger control will be supplied to Fu Re The supply amount of the heat transfer medium of the medium supply pipe 15 () and the output of the above-mentioned heating bodies 1 1 6, 1 1 7, 1] 8. With such a structure, it is possible to control the temperature of the mounting surface 1 0 9 in the above three slightly concentric areas 1 2 3 * 1 2 4, 1 2 5 Printed by the Employee Consumer Cooperative of the Central Department of Economics of the Ministry of Economic Affairs Don't do it independently, set different temperatures in these three areas. Then, the semiconductor wafer W held on its mounting surface is sucked, and since the heat of the mounting table 106 will be supplied from the back side by heat transfer, its temperature distribution will be corresponding to the three fields of the mounting table 1 0 9 , The wafer W will form a slightly concentric shape corresponding to the three areas 1 2 3, 1 2 4, 1 2 5 1 2 6 * 1 2 7 * 1 2 8 ° As a result, the concentration of the processing gas The thickness of the semiconductor layer of the thin layer of the boundary layer is around the temperature of the field 1 2 8 is set to be lower than that of the center of the semiconductor wafer 1 2 6 of the thickness of the concentration block boundary, although it has the general standard of the Chinese standard. (CNS) A4 specification {Ιϋχ 297 g) ~~., () — B7 V. Description of invention (27) The existence of layer distribution will try to make the film formation rate uniform. Β The reason will be explained below. In the sheet-type CVD apparatus 1 shown in FIG. 18, a predetermined processing gas, such as S, is processed in the processing chamber 105 through a hole 1 0 4 perforated plate 10 3 provided in the bottom surface of the shower head 102. When Η 4 etc. are introduced at a uniform flow rate, the processing gas will show the gas flow shown by the arrow symbol. The flow velocity U of the processing gas on the semiconductor wafer W will become a function of the radius r of the wafer, as shown in Figure 20. The flow rate will be distributed faster toward the outer periphery. At this time, the thickness of the processing gas concentration boundary layer, which has a great relationship with the movement amount of the film-forming substance, < 5 is a function of the flow velocity u of the processing gas, so the distribution of the thickness of the concentration boundary layer on the surface of the semiconductor wafer As shown in Figure 21 *, the thicker the center, the thinner the end, and as a result, the temperature will become higher from the center to the end. Therefore, by setting the temperature of the area around the semiconductor wafer 1 2 8 where the thickness of the processing gas concentration boundary layer is thinner to a lower temperature than the area 1 2 6 at the center of the semiconductor wafer where the thickness of the Australian boundary layer is thicker, it can be uniform Film formation. Printed by the Beigong Consumer Cooperative of the Central Bureau of Economic Affairs of the Ministry of Economic Affairs. At the same time, on the side of the processing chamber 105, as in the apparatus of the first form, a loading fixing chamber 52 is provided via the gate valve 51. Next, the operation of the CVD apparatus configured in this manner will be described. "First" As in the first embodiment, the semiconductor wafer is carried from the cassette storage chamber into the loading and fixing chamber 52, and then from the loading and fixing chamber 52 to the processing chamber Within 1 0 5.

Description of the invention (39) An insulating layer is formed to prevent the metal part from being exposed according to the presence of the insulating department. Therefore, it is possible to prevent the discharge from the electrical conductor under a reduced pressure environment. — In the support section 3 0 4 B The surrounding area of the brazed portion 3 〇4 D is provided with a cooling structure. That is, such a cooling structure is to prevent thermal peeling at the brazed portion 304 D and exposure of the support portion 304 B in the atmosphere It is installed in the danger of high temperature. Therefore, a water cooling jacket 3 1 2 along the circumferential direction is provided at the position where the support 3 0 8 and the brazed portion 3 0 4 D face each other, and the water cooling jacket 3 1 2, respectively The feed water for circulating cooling water, the drain pipes 3 1 4 and 3 1 6 are connected. Then, according to this cooling structure, the temperature of 300 D at the brazed portion is maintained at, for example, about 500 ° C. Such a cooling structure is also effective for suppressing damage to the brazed portion due to temperature rise at the plug terminal 3 0 4 that requires a large amount of current to be supplied to the power supply portion of the heater. Next, the operation will be described. In the processing chamber 2, the electrode portions 2 4 and 25 of the electrostatic clamp of the mounting table 21 and the power supply portion to the heater 26 are incorporated in the manufacturing process. That is, when the power supply unit is incorporated, the socket terminal 302 will be buried on the mounting table 21 side. Then, the socket terminal 3 0 2 will be subjected to a surface treatment, but when this surface treatment is to form the carbon layer 3 ϋ 2 A constituting the conductive layer according to the C: VD treatment, each socket terminal 3 0 2 is equivalent to The part that supplies electricity to the electrode portions 2 4 and 2 5 of the electrostatic clamp 3 0 0 a (refer to FIG. 2 9) and the part that supplies electricity to the heater 26 to 3 0 0 b (refer to FIG. 2 9) The treatment is formed as a wiring part at the time of coating or subsequent pattern formation.

In addition, although FIG. 30 shows that the wiring of both sides is pulled out from the same socket terminal 3 0 2 for convenience, it is of course actually pulled out from the socket terminal 3 () 2 corresponding to the above power supply section . When the carbon layer 3 0 2 A is formed in this way, a P—BN (pyro-boron nitride) treatment coating is formed on this layer to form an insulating layer 3 0 2B. The surface treatment at this time can also be formed together with the above-mentioned carbon layer 30 2A and the wiring between the electrode portions 24, 25 of the electrostatic clip or between the heater 26, together with the insulating layer on the electrostatic clip side . Then, since the inner peripheral surface near the inner bottom of the socket terminal 3 0 2 is cut off by machining, the insulating layer 3 0 2 B is removed to form a contact 3 0 2 C. On the one hand, the insertion of the plug terminal 3 0 4 of the socket terminal 3 0 2 will integrate the conductive part 3 0 4 which is integrated by latching the front end of the support 3 (3 8 brazed support part 3 0 4 B A is inserted into the socket terminal 3 〇2. At this time, the conductive portion 3 0 4A will be bent in the direction of diameter reduction and inserted due to the size difference between the socket terminal 3 0 2 and the conductive portion 3 0 4 A, insert This is so-called press-fitting, and it will be pressed to a position where an appropriate gap (the gap indicated by the symbol P in the garden 3 1 C) is provided between the front end of the conductive portion 3 0 4 A and the inner bottom of the socket terminal 3 0 2 Therefore, the conductive portion 3 0 4 A will cause the force at the time of restoring the bending deformation to act from the contact 3 0 2 C of the socket terminal 3 0 2 to the opening. Therefore, the socket terminal 3 0 2 The gap between the inner surface and the outer surface of the plug terminal 3 〇4 will be extremely small. Therefore, the electrons emitted from the contact 3 0 2 C will be limited to the impact frequency of the gap.

At this time, the power is supplied to the electrodes 2 4, 2 5 and the heater 2 6 from the contact 3 0 2 C of the socket terminal 3 () 2 via the wiring according to the carbon layer 3 0 2 A The Central Standards Bureau of the Ministry of Economic Affairs, the Industrial and Consumer Cooperatives printed in accordance with this form, the plug terminals used when supplying power from a high-voltage power supply and the plug terminals thrown away when supplying large-capacity power will make it common to each other. structure. Therefore, even if the power supply contents are different, it is not necessary to prepare and suitable terminals, so the structure can be simplified. In addition, since the assembly procedure for inserting the socket terminal side can be used for the plug terminal, the power supply unit can be assembled according to the simple operation of wearing only from above, and maintenance becomes simple. In this way, according to this form, the Chinese national standard (CNS > A4 is now available [210X297mm]) is adopted as the paper standard for the heater is fed to the power. The A7 __B7 is printed by the Consumer Cooperative of the Central Pants of the Ministry of Economy 2. Description of the invention (42) The piece is formed with a bottom opening, the bottom side is used as a conductive contact, and the opening end side is used as a socket terminal with a green layer structure. The plug terminal is inserted here for power supply, so it can be used The simple structure reduces the impact frequency of electrons at these contacts. Therefore, it is possible to prevent the collapse of electrons due to the electrons discharged from the contacts, so that discharge can be prevented even when wiring under the void. Such a discharge prevention effect will vary depending on the shape of the socket terminal 302. This case will be explained based on Fig. 34. Here, when the depth L and the diameter D of the cap opening η portion of the socket terminal 302 made of polytetrafluoroethylene are changed, the relationship between the vacancy in the processing chamber and the discharge start voltage will be shown. In addition, as the depth L of the opening, 16 mm, 20 mm, and 23 mm are used, and as the diameter D of the system, 6.0 mm, 6.25 mm, and 6.4 mm are used. At the same time, the length of the conductive part 3 0 4 A of the plug terminal 3 0 4 is 25 mm, the length of the exposed part is 8 mm, and the diameter is 0 5 · 'The test was conducted at 2 5 ° C. As shown in Fig. 34, the larger L is, the smaller D is, that is, the deeper the contact position and the narrower the width of the opening, the more stable the discharge start voltage will be, that is, it is known that the discharge will not be easy. According to this embodiment, since the surface of the plug terminal other than the contact is coated with the insulating layer, the effect of preventing discharge is exerted. In addition, the conductive layer provided on the socket terminal can be coated together with the electrode part of the electrostatic clip heater of the power feeding part. Therefore, the conductive layer of the socket terminal and The electrodes of each part or the insulating layer at the time of electrostatic clamping are combined to form.

The special blocking structure between the description of inventions (43) can simplify Meidao, and accordingly, can reduce wiring costs. At the same time, in this form, the contact of the socket terminal is not only the side near the inner bottom, for example, when the thermal expansion of the plug terminal is not too large and the contact state does not change, it can also be formed on the bottom surface of the socket terminal. As long as the tip of the plug terminal has a habit of crimping against the bottom surface, it may be contacted. In addition, this form is used as a socket terminal, as long as it has a shape with a bottomed opening, so it is not only used as a cap as in the above embodiment, for example, when the counter electrode of a plasma etching apparatus and the mounting stage are a conductor It is also possible to provide a recess with a bottom opening formed on the mounting table. In this case, the bottom of the bottomed opening can be used as a contact, and an insulating layer can be formed on the opening end side of the bottomed opening to obtain the same effect as the above example. Furthermore, although the above-mentioned forms are shown with respect to the thermal CVD apparatus, it is not limited to this. The present invention can also be applied to plasma CVD apparatuses, and other empty processing apparatuses, such as etching apparatuses, and ashing Device, splash device, etc. At the same time, while printing and printing at the Beigong Consumer Cooperative of the Central Standard Mou Bureau of the Ministry of Economic Affairs, although it is used as an electrostatic clip bipolar type with two conductors as electrodes, it can also be used as an electrode only Use one conductor 2 4 unipolar type. At the same time, it can also be configured as the apparatus shown in Figs. 36, which has both the division heating of the object to be processed according to the mounting table of the third aspect and the division control of the processing gas flow rate according to the shower head of the fourth aspect. At this time, it will be possible to increase the control parameters, and it will be able to increase the uniformity of film formation.
