處理室主體312包括第一側壁302 ' —第二側壁304、一 第二側壁306、底部308和頂部310。一第四側壁318(部分 圖示在第3圖中）與第三側壁306相對。主體3 12由一種適 於在真空狀態下使用的剛性材料構成。處理室主體312由單 獨一塊（如’ 一片）銘或其他適合的材料製成，或由模組型 材製成。
基板210由第一移送室320的底部308和用以界定出第 二和第三基板移送室322、324底部的内壁314，此兩者上方 的多個基板支撐件344來支承。基板支撐件344被間隔設置 以於一高於底部308(或壁314)的高度處來支承基板21〇, 以避免基板與處理室主體312接觸。基板支撐件344係配置 成使基板所受到的括損和污染達到最小程度。在第3圖續示 的實施例中，基板支撐件344是具有圓形頂端346的不鏽鋼 銷。其他合適的基板支樓件揭示在2〇〇3年3月5日申請的 美國專利申請Νο·6,528,767、2001年1〇月27曰申請的美國 專利申請Ν〇·09/982,406以及2003年2月27日申請的美國 專利中請No.60/376,857中。 每一基板移送至320、322、324的至少一側壁包括至少 11 1352373 411的一個孔504。該鐘形螺絲41〇的一頭部5〇2能夠防止 該鐘形螺絲41〇通過該彈性襯套411。該襯套⑴之彈性允 許該鐘形螺絲41〇可相對於該門構件4〇2做萬向樞轉（亦即， 在至少二平面轉動，例如繞著χ軸及ζ轴轉動 該彈性襯套4 1 1的内直徑504比該鐘形螺絲4丨〇的直徑 5〇6來得大。因此，該鐘形螺絲41〇能夠在該彈性襯套々η 内橫向移動，而使該門構件402可相對於該桿臂413横向移

型式。適合之聚合物材料的例子可, 〇竹刃例于了以疋聚胺基甲酸酯聚醯 胺-醯亞胺，例如 TORLON®、VITOXT® ^^ V 11 0N®、或其他適合的彈性材 料。其他可構成該襯套411的其他性材料的例子包括彈性形 式，例如碟形彈簧（BeUeviUe springs)，係由金屬及其他適合 的彈簧材料製成。 該襯套411之彈性允許該連接構件45〇可改變相對於該 桿臂413及/或相對於該門構件4〇2之角度及横向位置兩者。 該襯套4Π的移動能夠彌補該負載鎖定室操作期間該門構件 402之方位改變。例如，當該門構件4〇2的末端向外移動（在 X-方向）使該門變得扁平併接萼該處理室主體312時，，該襯 套411可在不必將過量的橫向力量轉移至該桿臂413的情況 下’吸納一往該鐘形螺絲41〇的橫向移動。因此，隨著該襯 套411可實質吸收該橫向力的轉移，該桿臂413不會被迫使 進入一個會產生束缚的位置。而且，該可形變的連接部419 可吸納該門構件402在曲度上的變化（圍繞Z_軸）而不會產生 束缚及/或使該桿臂413(或軸404、406)變形，因此，能夠將 磨耗減少最低並減少潛在的粒子源。此外，當藉由與該處理 15 1352373
度差異（例如曲狀和扁平狀），係藉由第6A-B圖所繪示之從該 門構件402末端延伸的虛線600、602之偏移來說明。該門 構件412之擴展導致該鐘形螺絲4丨〇改變方位並相對於該桿 臂413呈某一角度的傾斜。該襯套411亦允許該鐘形螺絲41〇 孝κ向移動’用以彌補該門構件402在長度的變化。該可形變 的連接部419亦允許該桿臂413，相對於通過該處理室主體 3 1 2之該轴404、406實質上維持無變化。此外，當該門構件 402框轉至其表面與反應室壁接觸對準而使該曲狀門構件 402變直時所導致之移動’該可形變的連接部419亦提供在 第二平面轉動。 第7圖係該密封塊組件408的一實施例的剖視圖》該密 封塊組件408包含一殼體702、一内襯套704' —外襯套706、 及一或多個轴密封件708。該殼體702通常藉由多數緊固件 710連結至處理室主體312。一個〇型環712配置在該殼體 702與處理室主體312之間’用以在其等之間提供一真空密 封。
該殼體702包含一通孔714其允許該軸406通過該殼體 702。該孔714在每一末端具有複數個鑽枉坑（c〇unterb〇res)， 用以收容該内外軸承704、706。複數扣環718用以防止該等 軸承704、706從孔714移出。該等轴承704、706係壓配在 該軸406’用以協助轉動。在第7圖所繪示之實施例，該軸 承 704、706 係交叉報轴承（cross-roller bearings)。 該一或多個軸密封件708係配置在一孔714内，並在該 第二轴406與該殼體702之間提供一動態真空密封。第7圖 17 1352373 所繪不之實施例’顯示多數個轴密封件7〇8被間隔物716隔 開。 該第二轴406之一内側末端720係以一種玎確實將旋轉 移動從該轴406轉移至該桿臂413的方式連結至該桿臂 413»例如’該桿臂413可以與該轴4〇6相匹配或者包括一 鍵來確保其旋轉。或者，桿臂413可以被夾在、釘在、壓配 在、焊接在或者黏接在轴406上。
第8圖繪示一桿臂413實施例的示意圖，隨著該第一軸 404的轉動運動’該第一轴4〇4之一外部末端740係以一種 可確實將該外部致動器臂414的移動加以轉移的方式，連接 至該外部致動器臂414。該第二轴406之配置也類似。例如， 該外部致動器臂414可以與該軸404相匹配或者包括一鍵 802來確保其旋轉。或者，内部致動器臂414可以被夾在、 釘在、壓配在、焊接在或者黏接在軸4〇4上。
第9-10圖描述門構件402的一實施例的主視圖和俯視 圖。門構件402通常是細長的，由鋁或其他適合的材料製造 而成°門構件402包括較長邊（major sides) 902、904，較 短邊（minor side) 906、908 ’ 一密封面 910 和一背面 912。 該桿臂4 1 3係個別藉由一可形變的連接部4 1 9連接到門構件 402的背面912的相對兩端，靠近較短邊906、908。在一實 施例中’門構件402是矩形的，並且在較短邊906、9〇8之 間的寬度至少為1260毫米。可以預見，門構件4〇2在寬度 上可長些或短些，以適合不同尺寸的基板。 密封概片（seal gland) 914形成在諸側902、904、906、 18 1352373 908裏面的密封面910内。該密封襯片914可限制門構件402 的中心部分，其可覆蓋通過處理室主體312的基板進出埠 316。密封件916 —般設計成當受到致動器330、430的擠壓 時，可防止門搆件402與處理室主體312間有接觸。在一實 施例中，密封件916由含氟聚合物或其他適合的材料製成的 0型環構成。其他密封材料的例子包括氟破化合物（fkm ) 或全氟彈性體（ffkm )、腈橡穆·（ nbr )和碎化物。可見，密
封件916和密封襯片914可被選擇性地設置在處理室主體 312 上。 該門構件402的該密封面910至少相對於連接較短邊 906、908的主轴1002彎曲。該主軸1 002平行於由門構件 402密封該處理室主體312的一密封表面ι〇12界定的一假相 線1〇〇〇。為清楚起見’在第1〇圖中，該密封表面ι〇ΐ2和該 門構件402顯示為一放大的間隔分離的關係。假想線〖 也可以平行於該轴404、406，並且與該較短邊9〇6、9〇8垂 直。在第10圖描述的實施例中，該密封面91〇相對於該線 900係凸出的，這樣當門構件4〇2閉合時，該密封面gw的 中心首先接觸到處理室主體312,藉此在門構件4〇2内部產 生彈力。 在操作中，與設置在較短邊906、9〇8上的桿臂々Η相連 的致動器330、430使門構件402旋轉關閉。由致動器、 43 0引起的曲狀的門上的負載力在笛n 取力在第11圖中由箭頭1102描 述。當該門旋轉關閉’由該彈性襯套41丨所接 听知：供之該鐘形螺 栓410的橫向移動’因而允許在一相對 、^稈臂4 1 3之縱向 19 1352373 移動。由於門構件402的彎曲，門構件4〇2的中心首先與處 理室主體312接觸。因為致動器33〇、43〇的力使門構件4〇2 變平，門構件402的弩曲就產生了一彈力從而增大了門構件 402中心區域的密封件9丨6。由門構件4〇2的彈力而引起的 負載力在第11圊_由箭頭n〇4描述。經過致動器 的門端部的高負載的合力被門構件4〇2的中心彈力抵消從 而在基板進出埠316的周圍均勻地施壓和載入密封件gw。
負載力1102、1104的合力總和在第u圖中由箭頭η %描 述》在致動器的合力和門構件4〇2產生的彈力的作用下，變 平的密封面910在通過處理室主體312的通道周圍提供均勻 的密封負載8i6 ’藉此確保了通道週邊的真空密封均勻而可 靠，同時增加了密封的期限。為了預先確定門的幾何尺寸和 理想的真空狀況，密封面川㈣曲程度將由先束的偏 析決定。 再者’當第一和第二桿404、4〇6比門構件4〇2和負載鎖 U⑽的寬度短時1的偏轉較小，從而使力更有效地從 致動益330、430傳遞到門構件402。較短的軸4〇4、4〇6還 可考慮利用較小的袖直徑，藉此減少與成本有關的長軸其 等因硬度需要更大的直徑和更大尺寸的相關硬體。另外 於内部致動器冑412被設置在處理室主冑316的凹部川 内’為了一提前確定的基板進出帛σ的寬度，負載鎖定室2〇〇 的寬度和内邛體積可以最小化以利於減少製造負載鎖定 200的成本，並藉由減小負載鎖定室綱的體積而增加 力，需要在運轉期間通風和栗送作業。 20 1352373 第7圊係沿著第4圖的線5_5截取的 pack assembly)的實施例的剖視圖。 塊組件（似1 第8圖是第2圏中的負載鎖定 視圖β Λ知*例的局部切開側
