Abstract
本發明係關於一種用於夾持工件(19)、特別是晶圓的真空吸盤,以及藉由X光螢光輻射而用於檢核工件、特別是晶圓的量測裝置與方法。
Description
本發明涉及用於夾持工件、特別是晶圓的真空吸盤,用於檢測由這種真空吸盤夾持著的工件的測量裝置,和用於檢測夾持在真空吸盤上的工件的方法。
一種真空吸盤由DE 202013102800 U1得知,其包括支撐或夾持表面,用於借助負壓加裁和夾持工件。具有支撐和夾持表面的夾持板被容納於基體中,該基體包括吸力連接部,用於連接到負壓裝置,以便在吸力開口中施加負壓。這樣的真空吸盤的缺點在於,若干吸力開口定位成相互平行並且共同地被一個負壓管線供應負壓,因此在接收和夾持較小的工件時也需要增大的負壓裝置能力。
一種用於檢測晶圓的真空吸盤由位於21354 Bleckede的Horst Witte Gerätebau Barskamp KG公司在2011年發佈的消息披露。這種真空吸盤具有由微孔材料製成的夾持表面。非常薄的工件被這種微結構以與級差無關和無損的方式固定。夾持表面被分為三個可切換的夾持區域,用
於不同尺寸的晶圓。然而,這種包括由微孔材料構成的真空吸盤的夾持板的缺點在於,在搬運期間非常敏感,並且在添加到或移動該表面時夾持功能受損。此外,這種真空吸盤在有限的程度內可用。另外,如果各種工件不能完全覆蓋選定區段的話,為了將工件固定到夾持表面上,夾持表面的微孔表面也需要高負壓性能。
本發明的目的是提出一種用於夾持工件、特別是晶圓的真空吸盤,其能夠實現將各種工件簡單且均勻地夾持在夾持板的支撐表面上。此外,本發明的目的還包括提出用在檢測工件的測量裝置中的真空吸盤和用於借助X光螢光輻射檢測這些工件的方法。
上述目的可通過一種真空吸盤實現,其中夾持板的支撐層中的每個吸力槽具有至少一個單獨的負壓,該負壓與相鄰的吸力槽分開,並且該負壓由控制器借助至少一個控制閥被選擇,以將負壓施加於相應的吸力槽。通過這種方式,被工件覆蓋的相應吸力槽或稱被覆蓋的吸力槽的相應控制基於被夾持工件的尺寸而實施,這樣,能夠以高度的有效性和減小的負壓裝置性能實現牢固地夾持工件。
優選地,支撐表面具有若干同心吸力槽具有至少一個吸力開口,吸力開口被連接有負壓管線,或者吸力開口連接著工作通道。特別是在具有圓形形狀的晶圓的情況下,由於吸力槽形成為圓形,被相應地調節到其尺寸的吸力槽靠近晶圓外周區域提供。這能夠實現牢固的夾持。因此,直徑更大的其它吸力槽不需要被供應負壓。因此,可以成功地節約能量。
真空吸盤優選可具有基板,其由用於借助X光螢光輻射檢測工件、特別是晶圓的材料製成,所述基板的原子序數被以這樣的方式選擇,即在X光螢光測量裝置的主輻射指向工件的情況下,小量的散射輻射被產生,並且螢光輻射是如此的小,從而能夠被吸收到被檢測物件的材料中。因此,能夠有益地實現完全或基本上完全的吸收。
作為替代方案,基板材料可以這樣選擇,其中材料的原子序數被以這樣的方式選擇,即指向工件的主X光輻射產生螢光輻射,其中螢光輻射的20%到80%被吸收到將被檢測的工件的材料中。因此,在利用檢測器檢測測量信號的情況下,未被吸收的螢光輻射可被用於評估。
真空吸盤的進一步優選實施方式提供了這樣的方案,其中至少三個升降銷被提供在基板中,所述升降銷可從位於夾持板的支撐表面中或下面的後返位置移動到延伸位置。這使得,例如,工件能夠在檢測過程開始時被裝配到升降銷上,特別是通過搬運裝置。接下來,在將搬運裝置從升降銷的區域移開後,可借助升降銷將工件輕柔地定位且安置在夾持板的支撐表面上,以便後續吸緊工件。通過相同的方式,在檢測之後可以利用升降銷將工件從支撐表面輕柔地抬升,以便隨後能夠於工移開或自動移開晶圓。
升降銷優選具有類似於吸力杯的支撐表面,或具有中心孔的接收元件,接收元件連接著負壓管線或吸力通道,以借助負壓產生保持力。該接收元件優選由彈性體製成,以便一方面避免劃傷工件,另一方面在施加負壓的情況下快速地構建真空用以將工件固定在升降銷上。
升降銷優選能夠通過設置在基體中的可移動的滑架被移位
至後退位置和延伸位置,其中,工作缸,特別是氣缸,控制滑架的移位動作。這樣,可產生具有這樣的平坦構造的真空吸盤,因為滑架的移位動作發生在XY平面中,而升降銷的伸出動作沿著垂直的軸線提供,特別是Z軸。另外,負壓裝置同時還可以用來控制工作缸。
可移動的滑架有益地具有傾斜控制表面,至少一個控制元件,特別是凸輪或是摩擦或耐磨軸承元件,被沿著所述控制表面引導,所述控制元件固定在升降銷上並且帶動升降銷移動。因此,滑架的移位動作可以直接轉化成升降銷的升降動作。
此外,升降銷優選被沿著導向套筒引導,從而能夠被抬升,所述導向套筒連接著基體中的負壓管線或吸力通道。因此,為升降銷提供了伸縮式結構,從而可以進一步實現真空吸盤的平坦結構。導向套筒優選牢固地固定在基體上,並且其內孔終止於吸力通道中。
可移動的滑架優選在基體中安置在支靠於基體上面的夾持板和設在基體底側的下側板之間。該滑架能夠被滑動地引導於夾持板和下側板之間,或借助滾輪或滾珠。作為替代方案,滑架可通過固定在基體中的導向元件被可移動地保持。
可移動的滑架優選設置在基體中的接收空間中,感測元件彼此面對著設置在接收空間的兩個末端區域上,所述感測元件基於滑架在接收空間中的位置檢測升降銷的後退位置或延伸位置。因此,能夠實現對這種真空吸盤的自動控制的監視。
此外,若干止動銷優選地設置在基體中,所述止動銷可從位於夾持板的支撐表面中或下面的後退位置移入伸出的止動位置。當在真絲
夾盤上手工裝配工件、特別是晶圓時,這些止動銷特別適用。如果不需要它們,例如特別是在自動裝配的情況下,它們可以被定位於夾持板的支撐表面中或下面。
一或多個止動銷優選被供應正壓以便移入伸出的止動位置。為此,在每種情況下為所述一或多個止動銷有益地提供供應通道,正壓被提供到所述供應通道中。因此,為實現工件的一定程度的夾持而配備的兩個或更多個止動銷可被同時控制。
此外,通過排空供應通道且借助與止動銷接觸的復位彈簧,止動銷可彼此獨立地移入後退位置。因此,即使是壓力供應發生中斷時,也可以確保止動銷不會相對於夾持板的夾持表面突伸,因此真空吸盤可繼續被使用。
優選地,每個吸力槽被配備至少兩個止動銷,所述止動銷能夠被公共的供應通道以正壓控制,其中,在每種情況下,所述至少兩個止動銷佈置在相應吸力槽的徑向外側,該吸力槽至少針對將被接收的工件的相應尺寸而被控制。因此,針對每種吸力槽尺寸分配相應的止動銷,使得真空吸盤能夠被用於若干工件尺寸。例如,可以夾持和檢測直徑為4"、6"、8"、10"和/或12"(英寸)的晶圓。
真空吸盤的進一步有益的實施方式提供了這樣的方案,即至少三個升降銷設置在最小的或第一吸力槽的外側,並且至少兩個止動銷配備給最小的或第一吸力槽,沿周向看相對於這些升降銷偏置。因此,所有將被真空吸盤接收的尺寸的工件可被各升降銷均等地接收,下降到支撐表面上,和/或再次抬升,並且類似地,因為工件被定位在相應的止動銷上,
能夠實現手工裝配。
真空吸盤的進一步優選實施方式提供了這樣的方案,即在每種情況下,至少兩個止動銷設置在額外兩個相鄰的吸力槽之間。佈置在相應的吸力槽內的止動銷優選沿直線相對於半徑方向對正。因此,對於接收在真空吸盤的夾持板上的不同尺寸的工件可以賦予相同的搬運要求。
真空吸盤的基體優選在指向夾持板的那一側具有相對於吸力槽匹配地延展的工作通道,所述工作通道連接著相對於夾持板的支撐表面中相應的吸力槽的至少一個吸力開口,並且優選地,每個工作通道由控制閥利用真空單獨地控制。因此,可實現這樣的平坦的構造以及對相應吸力槽的選擇性控制。
本發明的目的還可通過一種利用X光螢光輻射檢測工件、特別是晶圓的測量裝置實現,其中根據上面描述的實施方式之一的真空吸盤設置在測量裝置的可移動的測量臺上。由於小的結構高度,這樣的真空吸盤可被用於現有的X光螢光測量裝置中。此外,由於對基板材料的選擇,能夠通過簡單的調節以適合於不同的測量物件和將被檢測的工件的材料。因此,相應的真空吸盤可被互換,或者,夾持板可被互換為不同的材料並且能夠固定到真空吸盤的基體。
本發明的目的還可通過一種利用X光螢光輻射檢測工件、特別是晶圓的方法實現,其中下面的步驟被特別提供:在工件裝配前,真空吸盤被啟動。這樣,升降銷被移位到相對於夾持板的支撐表面的延伸位置。接下來,將被檢測的工件可由搬運裝置放置在升降銷上,並且負壓可被施加到升降銷以使得將被檢測的工件被
固定到升降銷。接下來,搬運裝置可被引導移出測量裝置。升降銷被控制進行移位動作,使得它們移到後退位置,並且工件被放置在支撐表面上。然後,對應於工件的尺寸,至少最外側吸力槽被供應負壓,並且工件被夾持在支撐表面上。在工件已被借助X光螢光輻射檢測後,供應負壓的至少一個吸力槽中的負壓被截止,並且升降銷被移入延伸位置。接下來,工件被搬運裝置抓持,並且施加於升降銷的負壓被截止。工件然後可借助搬運裝置被從測量裝置移開。
優選地,在工件被夾持在夾持板的支撐表面上期間,施加到升降銷的負壓可以持續。作為替代方案,可以在將工件夾持在支撐表面上的時間點切斷負壓。

下面將借助附圖中展現的例子來詳細描述和解釋本發明及其進一步有益的實施方式和進展。根據本發明,能夠從描述以及附圖中確定的各種特徵可以單獨或以任何方式組合來實施。附圖中顯示了:圖1 具有真空吸盤的X光螢光測量裝置的立體圖;圖2 根據圖1的真空吸盤從上方所作的示意圖;圖3 真空吸盤沿著圖2中的線II-II的示意性剖視圖;圖4 圖3中的細節B的示意性放大圖;圖5 圖3中的細節C的示意性放大圖;圖6 帶有升高的夾持板的真空吸盤的立體圖;圖7 真空吸盤的基體從上方所作的示意圖;

一種借助X光螢光輻射實施測量的測量裝置11以立體圖的方式展現於圖1中。該測量裝置11包括測量台12,其為可移動的,例如,在XY平面中,借助直線軸線系統14。測量裝置11的殼體16中設有用於產生主輻射的輻射源和用於將主X光輻射引導到支靠在測量台12上的工件19上的一或多個分光元件,它們沒有詳細示出。此外,測量裝置11在殼體16中包括檢測器,借助該檢測器,受工件19限制的次級輻射被檢測。該檢測器連接著控制裝置17,以便評估檢測到的測量信號,並且有益地通過顯示器展示它們。
根據本發明的真空吸盤(吸盤)18,其在後面的圖中被詳細繪
示,用於接收和夾持工件19、特別是晶圓。該真空吸盤18可以安裝或固定在測量裝置11的測量台12上,以便固定用於檢測、例如借助X光螢光輻射檢測的工件19,特別是晶圓。該工件19可以例如通過搬運裝置89安置到真空吸盤18上。
在圖2中,真空吸盤18從上方所作的示意圖書皮繪示。其包括夾持板21,夾持板具有支撐表面27,其包括若干吸力槽22、23、24、25、26。這些吸力槽22至26由引入夾持板21的支撐表面27中的圓形凹坑形成。優選地,吸力槽22至26相對於彼此同心地佈置。吸力槽22至26的數量可針對測量物件調節,取決於夾持板21和/或將被接收的工件19的尺寸。
此外,真空吸盤18包括升降銷29,例如三個升降銷29。這些升降銷優選地佈置在第一吸力槽22和第二吸力槽23之間。特別是,這些升降銷沿整個圓周均勻地分佈。升降銷29優選由貴金屬製成。
真空吸盤18此外可具有止動銷31,其中可以給每個吸力槽22至26分配至少兩個止動銷31,以便實現工件19的定位和對正。止動銷31佈置成相對於彼此偏置,例如,特別是相對於彼此偏置90度的角度。對於兩個較小尺寸的將被接收的工件19,在每種情況下分別有例如三個止動銷31配備給第一吸力槽22和第二吸力槽23,其中,兩個止動銷31位於公共的直線上以便獲得在工件19的止動表面上的額外定位。
真空吸盤18包括基體33,其接收夾持板21。夾持表面21可以設置成固定在基體上,例如通過粘接、螺合或鏘接。作為替代方案,夾持板21還可以設置成在基體33上互換。為此,可拆卸的固定元件優選被
提供。夾持板21可由不同的材料構成,並且根據測量物件而選擇。
致動器34設置在真空吸盤18的前表面上,所述致動器控制未詳細示出的多位元閥,以便根據將被夾持的工件19的尺寸相應地啟動對應的止動銷31。這將在後面詳細描述。若干連接部43設置在罩32下面,所述連接部將在後面借助圖7和8討論。
在圖3中,沿著圖2中的線II-II的示意性剖視圖被繪示。真空吸盤18的基本結構在本圖中示出。夾持板21位於基體33的上側。下側板36固定在基體33的底側。用於控制吸力槽22至26的工作通道37、38、39、40、41(圖6)佈置在夾持板21和基體33之間。作為示例,這些工作通道37至41在圖4中放大展示,並且在圖6中以上方立體圖展示,其中,圖6描繪了夾持板21去除的情況下的基體33的立體圖。工作通道37至41優選引入到基體33的表面中。作為替代方案,這些工作通道也可以引入到夾持板21的底側中。吸力槽22至26設置在夾持板21的上側。例如,這些吸力槽被形成為矩形槽,並且沿基體33的方向從支撐表面27略微延伸。至少在每個工作通道37至41和配備給工作通道37至41的每個吸力槽22至26之間分別設置至少一個吸力開口35,以將吸力槽22至26連接到工作通37至41。根據圖3的細節B在圖4中被放大繪示。
圖3中的細節C在圖5中被示意性放大繪示,其中,止動銷31在圖3中繪示於後退位置,在圖5中放大繪示於延伸位置。止動銷31被接收於基體33中的接納件53中,其中,止動銷31插入活塞54中。活塞54被可移位地引導於接納件53中。復位彈簧55佈置在止動銷31和活塞51之間。該復位彈簧確保,當止動銷31上的壓力表面56不被供應正壓時,止
動銷31被移入後返位置。這樣,止動銷31的前表面57位於夾持板21的支撐表面27中或下面。接納件54被供應正壓以產生和維持止動銷31的伸出動作,所述正壓作用於壓力表面56。墊圈58防止通過基體33和夾持板21中的開口吹出,止動銷31延伸穿過所述開口。用於所述正壓的供應通道48通過密封墊61被相對於相鄰供應通道49、50、51(圖7)密封,該密封墊借助於中間板62被夾持固定到基體33。止動銷31優選由貴金屬製成。
位於拆除的夾持板21中的基體33的立體圖被繪示在圖6中。從該圖中,在吸力槽22至26下面延伸的各工作通道37、38、39、40、41的延展路徑可以看到。通過在基板33中引入工作通道37至41,可以產生平坦的構造以向吸力槽22至26供應負壓。
從圖7可以看出,每個工作通道37至41配備有一個連接孔42、42.1、42.2、42.3、42.4、42.5,所述連接孔分別通向連接件43,負壓管線能夠分別連接到所述連接件。作為替代方案,連接孔42.4和42.5可以通向連接件43。這些連接件43中的每個分別連接著控制閥91、92、93、94並且分別被該控制閥91至94控制。控制器96被設置以控制這些控制閥91至94。這些控制閥91至94中的每個被該控制器96單獨地控制。該控制器96可以連接著控制裝置17。工作通道37至41由負壓裝置97供應負壓。
此外,連接件43設置在基體33上,由控制閥95控制。該控制閥95調節負壓向升降銷29的施加。這更詳細地顯示於圖13。該控制閥95也被該控制器切換(開關)。
此外,在基體33的上側,設有四個饋入通道44至47,通過這些饋入通道,正壓可以分別導入與之相連的供應通道48至51。這些供
應通道48至51可以由多開關閥控制,所述多開關閥通過操控元件34選擇。這些供應通道48至51由正壓裝置供應正壓。這可以通過單獨的正壓裝置實現,甚至可以通過相應地控制負壓裝置97實現。
每個供應通道48至51配備有至少兩個止動銷31。例如,饋入通道44終止於供應通道48,該供應通道中可以控制例如一共三個止動銷31,所述止動銷佈置在第一吸力槽22和第二吸力槽23之間或相應的工作通道37、38之間。該饋入通道44被供應壓縮空氣,例如,如果直徑為4"(4英寸)的工件19、特別是晶圓將被放置和夾持的話。饋入通道45提供給6"晶圓,饋入通道46提供給8"晶圓,而饋入通道47提供給12"晶圓。
饋入通道44至47和供應線路48至51的延伸路徑也可從根據圖8的從下方所作的基體33的視圖中清楚地看出。
在饋入通道44至47的區域,基體33中的工作通道39至41實際上被中斷;然而,在這些區域施加真空在每種情況下足以在相應的吸力槽22至26內獲得圓形真空,由此實現將工件19的平坦地支撐在夾持板21的支撐表面27上。
基體33中的接收空間64在圖7以及圖8中給出,在其中設有可移動的滑架65,如特別在圖8中被繪示。該滑架65接收三個升降銷29。借助由缸66、特別是氣缸控制的滑架65的移位動作,升降銷29被從後退位置移入延伸位置。連接部68連接著缸66上的連接部69以控制缸66。連接部71和72連接著彼此以控制相對方向的移位動作。這些連接部68、71在每種情況下由控制器通過控制閥98、99控制,或通過對應於期望的移位動作的公共控制閥控制。缸66通過壓力裝置100被供應正壓。
缸66的供應空氣和排放空氣通過控制閥98、99被調節。缸66可以具有可調的末端位置緩衝體。因此,輕柔地升降所述升降銷29以便在夾持板21的支撐表面27上放置和抬升工件19可以被調節和實現。控制閥98、99借助連接部68、69連接在真空吸盤18中以便供應用於缸66的供應空氣,所述連接部包括單向限流器以便至少限制排放壁氣。
感測元件67彼此相對地佈置,以便檢測升降銷29的相應的後退位置或延伸位置。這些感測元件檢測滑架65在接收空間64中的位置並將信號發送給控制器96和/或控制裝置17。由於升降銷29的受迫引導,升降銷29的位置也可利用滑架65的位置檢測到。
帶有升降銷29的滑架65的立體圖被繪示在圖9中。圖10展示了升降銷29的第一剖視圖。圖11展示了進一步的沿著圖9中的線XI-XI的剖視圖。
滑架65優選大致為H形,其中,縱向凹坑74提供在一條腿中,升降銷29在所述凹坑內可移動。升降銷29連接著至少一個控制元件75,特別是凸輪或是摩擦或耐磨軸承元件,其可沿著傾斜的控制表面76移動。滑架65在XY平面中或根據箭頭77所示的移位動作產生垂直於所述平面定位的升降銷29的伸出和後退動作。因此,升降銷29被引導成可沿著導向套筒78豎直移動,從而能夠被從後返位置移入繪示在圖10和圖11中的延伸位置。所有三個升降銷29能夠通過滑架65的移位動作而被上下移動。
在其上端,升降銷29具有類似於吸力杯的接收元件81,其優選由塑膠形成。孔82設置在接收元件81內,所述孔與導向套筒78對正,以使得導向套筒78產生的負壓也推抵於接收元件81。在支撐工件19時,
工件被固定在支撐元件81上。導向套筒78和各升降銷29通過公共的吸力通道84連接著彼此。這樣的吸力通道84在圖12中從下側板36下麵所作視圖中被顯示。圖中所示的各分支展示了於相應的導向套筒78之間的連接部設置在吸力通道84的相應末端。負壓通過負壓裝置97被產生在吸力通道84中,例如,通過連接孔85和分支通道86。真空的施加和截止由控制器96和控制閥95調節。工作通道84優選被引入下側板36中,並且該工作通道又通過單獨的罩板87密封。
對圖1和圖14和15進行考察,下面描述工件19的自動裝配和檢測。
工件19被根據圖1的搬運裝置89從圖中未示出細節的料箱或供給裝置抓取,並被供應到測量裝置11。滑架65被缸66在真空吸盤18中移動,以使得升降銷29從後退位置移入示於圖14的延伸位置。例如,該延伸位置也展示於圖10。接下來,借助搬運裝置89,工件19被放置,優選在精確位置,在升降銷29的接收元件81上。接下來,負壓被施加到升降銷29,以使得工件19因真空的作用而被固定到升降銷29。接下來,搬運裝置89被引導移出測量裝置11。
接下來,缸66再次被控制,以將滑架65移動到進一步的位置,以使得升降銷29降低和後退。這可以通過至少一個控制閥98、99實現,並且被感測元件67監視。工件19輕柔地到達支靠在夾持板21的支撐表面27上的狀態。在降低之前或期間,並且如果適宜的話也在降低之後,相應地提供的吸力槽22至26被供應真空,對應於工件19的尺寸,以使得工件19被固定到夾持板21。例如,根據圖15的工件19為8"晶圓。在這個點上,
當工件19被固定到夾持板21時,升降銷29中的負壓可以由控制器96截止。該負壓也可以繼續保持恒定。接下來,借助X光螢光輻射進行檢測和/或測量工件19。在完成檢測和/或測量後,相應的吸力槽22至26中的真空被解除,並且,如果升降銷29中的真空已經被截止的話,在吸力槽22至26中的真空被解除之前,升降銷29中的真空被再次啟動並接通。在此之後進行滑架65的移位動作,以使得工件19再次相對於支撐表面27抬升。接下來,搬運裝置89再次進入測量裝置11中。特別地,搬運裝置到達工件19下麵。在切斷升降銷29上的真空後,工件19可以被引導出測量裝置11,並且被堆疊或供給以使用於進一步的工藝。
至少吸力槽24被供應真空。優選地,較小的吸力槽23和/或22也被供應真空。吸力槽25和26因此不被供應真空,因為它們不被工件19覆蓋。
工件的手工定位和放置,即手工操作,描繪於圖16和17中。為了根據圖17檢測工件19,其為例如4"晶圓,操控元件34被初始調節到4"。然後,饋入通道44和供應通道48通過多開關閥被供應壓縮空氣,由此配備給吸力槽22的止動銷31.1、31.2、31.3伸出。接下來,工件19可以將其平直段20放置在兩個相鄰佈置的止動銷31.1和31.2上,並且與第三止動銷31.3對正。在止動銷31伸出的同時,真空可以產生在吸力槽22中。然而,也可以在放置工件19和將其相對於止動銷31.1、31.2、31.3對正後產生該真空。為了移除工件19,在相應的吸力槽22至26中初始切斷真空,在示例性實施方式中為吸力槽22。然後工件19可被手工移除。作為替代方案,也有可能對升降銷29進行控制而將工件19相對於支撐表面27升高,以便
能夠容易地移開工件。
