Description

晶圓保持器
本發明係有關一種晶圓保持器,特別是關於一種用於限制晶圓轉動之晶圓保持器。
請參照第一A/一B圖,第一A圖顯示傳統晶圓保持器100的剖面圖,第一B圖顯示傳統製程之晶圓140的示意圖。晶圓保持器100包含保持器主體110及複數支撐件120,其中支撐件120間隔環設於保持器主體110內側。而於製程中,晶圓140則係以面朝下(face-down)的方式設置在支撐腳120上。因此,如第一B圖所示,晶圓140設置以對應於支撐腳120之表面處,即對應產生壓痕(mark)142A。
然而,由於晶圓140在製程過程中往往須保持在高溫狀態,因此一般製程係從晶圓保持器100之底部開口130向晶圓140予以加熱,並且施加反應氣體於晶圓140表面以進行磊晶成長。如此一來,使得晶圓140因受熱形變及受氣體衝擊而產生滑動或轉動現象,導致晶圓140之表面對應增加產生壓痕142B,從而讓晶圓140實際可使用之表面區域範圍受到限縮,而無法提升以獲致其最佳使用率。
鑑於上述,因此亟需提出一種具有新穎機構的晶圓保持器,用以改善傳統晶圓保持器的缺點。
鑑於上述,本發明實施例的目的之一在於提出一種晶圓保持器,以改善晶圓於製程中產生轉動或位移的現象,使降低晶圓表面的壓痕面積,進而提高其製程良率及使用率。
根據本發明實施例,一種晶圓保持器,其包含保持器主體、支撐件及限制件。保持器主體具有圓形通孔。支撐件包含一支撐主體及複數個支撐腳。支撐主體固定於圓形通孔上,而支撐腳間隔環設於支撐主體之內側壁,用以支撐一晶圓。限制件固定於支撐主體上,且位於相鄰兩支撐腳之間,其中限制件設置對應朝向該晶圓之一平邊,用以限制晶圓產生轉動。
為了使本發明之敘述更加詳盡與完備,可參照所附之圖式及以下所述各種實施例,圖式中相同之號碼代表相同或相似之元件。另一方面,眾所週知的元件與步驟並未描述於實施例中,以避免造成本發明不必要的限制。
請同時參照第二A至二C圖,第二A圖顯示本發明之一實施例之一種晶圓保持器200的局部立體示意圖,第二B圖係顯示晶圓保持器200的局部上視圖,第二C圖則顯示將晶圓240設置於晶圓保持器200的示意圖。如圖所示,晶圓保持器200包含保持器主體210、支撐件220及限制件230。保持器主體210具有一圓形通孔212。支撐件220包含支撐主體222及複數個支撐腳224。支撐主體222固定於圓形通孔212上,支撐腳224則間隔環設於支撐主體222之內側壁,用以支撐一晶圓240。限制件230則固定於支撐主體222上,且位於相鄰兩支撐腳224之間,其中限制件230設置對應朝向晶圓240之一平邊242,用以限制晶圓240產生轉動。此外,於一實施例中,保持器主體210、支撐件220及限制件230可根據實際設計及需求,而採一體成形的製程。
更進一步地說,每一支撐腳224具有一第一支撐面226用以支撐晶圓240。然而,支撐主體222及支撐腳224亦可視實際設計及需求,予以採一體成形的製程。此外,限制件230包含一限制主體231,其中限制主體231具有一限制面232,對應朝向晶圓240之平邊242,用以限制晶圓240產生轉動。
在此實施例中,限制件230可更包含一支撐凸塊233。支撐凸塊233凸設於限制主體231的限制面232之下端。其中,支撐凸塊233具有一頂面234,用以支撐晶圓240。更具體地說,支撐凸塊233之頂面234的水平高度係與每一支撐腳224之第一支撐面226的水平高度大致一致。如此一來,當晶圓240配置於晶圓保持器200時,晶圓240可同時設置於支撐腳224之第一支撐面226及支撐凸塊233之頂面234上。
接著,如第二C圖所示,由於限制主體231係凸設於支撐件230之支撐主體222上,因此當晶圓240因受熱形變而向外擴張或受到反應氣體衝擊發生位移時,晶圓240之平邊242將先抵觸至限制主體231的限制面232,而致使晶圓240無法產生轉動或位移。另外,在一實施例中,限制面232與晶圓240之平邊242的間距係介於0.05毫米(mm)至1毫米(mm)之間。再者,於第二C圖所示之實施例中,限制面232之長度(L1)係大於晶圓240之平邊242的長度(Lw)。然而,本發明不以此為限,限制面232之長度(L1)亦可根據依據實際製成需求,而予以調整為小於或等於晶圓240之平邊242的長度(Lw)。
請繼續參照第二D圖,其顯示均熱板250及晶圓240同時設置於第二A圖之晶圓保持器200的示意圖。如圖所示,晶圓保持器200可更包含一均熱板250,且均熱板250可設置於支撐件220之支撐主體222的第二支撐面228上,其中第二支撐面228係位於第一支撐面上方。如此一來,當進行加熱製程步驟而從晶圓240下方處予以加熱時,由於均熱板250藉由支撐件220而配置於晶圓240上方處,所以即可讓位於均熱板250及晶圓240之間的腔體氣體進行熱對流,致使晶圓240之表面可有效均勻受熱,從而大幅提升製程良率。
接著,請同時參照第三A圖及第三B圖,第三A圖顯示本發明之另一實施例之一種晶圓保持器300的局部立體示意圖,而第三B圖則顯示將晶圓340設置於晶圓保持器300的示意圖。如圖所示,限制件330可包含複數個限制凸塊331。限制凸塊331係間隔設置於支撐主體322之內側壁上,其中每一限制凸塊231具有一限制側面332對應朝向晶圓340之平邊342。如此一來,由於此些限制凸塊331係凸設支撐主體222之內側壁上,且可具有大致相同的寬度,所以當晶圓340因受熱形變而向外擴張或受到反應氣體衝擊發生位移時,晶圓340之平邊342將先牴觸到限制凸塊331的限制面332,而致使晶圓340無法產生轉動或位移。其次,在一實施例中,限制凸塊331與晶圓340之平邊342的間距係可介於0.05毫米(mm)至1毫米(mm)之間。
再者,如第三B圖所示,每兩相鄰限制凸塊331的間距(L2)係小於或等於晶圓340之平邊342的長度(Lw)。因此,當晶圓340因受熱形變向外擴張時,多個限制凸塊331的側面332將同時對應抵觸晶圓340之平邊342而予以固定之,以有效限制晶圓340進一步產生轉動或位移,從而有效減少晶圓340表面的壓痕面積範圍。
以上所述僅為本發明之較佳實施例而已,並非用以限定本發明之申請專利範圍;凡其它未脫離發明所揭示之精神下所完成之等效改變或修飾,均應包含在下述之申請專利範圍內。
