1364524 九、發明說明: 【明所屬技領^^ 3 本發明關於乾燥一表面之乂法。更具體地,本發明關 於乾燥一碟型物品之一表面之方法’其包含用一清洗液覆 5 蓋該表面和移除該清洗液。 【先前技術3 供乾燥一碟型物品表面之方法典型用於半導體產業, 以供生產製程期間清潔矽晶圓(例如光刻前的清潔、CMP後 的清潔、及電漿處理後的清潔)。但是,此類乾燥方法可應 10 用于其餘類盤狀物品,例如實密碟片、光罩、圖罩、磁碟 或平板顯示器。當用於半導體產業時,其也可應用於供生 產積體電路之玻璃基材(例如絕緣體上矽層積製程)、ΙΠ_ν 基材(例如GaAs)或其它基材或載體。 右干種乾無方法習知於半導體產業。許多乾燥方法利 15用一界定的液體/氣體邊界層。此類.乾燥方法或以Marangoni 乾燥方法稱,更廣為人知》 US 5,882,433揭示一組合式Marangoni旋轉乾燥方法。 其中,去離子水被配注於一晶圓上,且限時氮和丙醇之 一混合物也被配注。該氮中的2—丙醇將影響該液體/氣體 20邊界層,而產生一表面梯度,引發水逃離該晶圓而不會在 該晶圓上留下任何液滴之效應(Marangoni效應)。當液體配 注件自該中心移至晶圓邊緣且當晶·圓旋轉時,該氣體配注 件是直接跟在該液體配注件之後,因此氣體直接將液體自 該晶圓移除。 5 1364524 此類物質可被稱作表面活性物質。但是,依本文定義, 表面活性物質必須是能夠降低水的表面能(表面張力)之物 質。這並非一定是表示,其必須為一表面活性劑,例如肥 皂。這僅應表示它應包含具有一極性和一非極性端之一分 5 子。 雖然因環境以及成本原因,該清洗液應該僅包含水和 該物質,但是任何其餘溶液亦可利用,·只要其達到上述標 準即可。 使用至少50wt.%水會產生該混合物具有高於室溫(25 10 °C)之一閃點之積極效應,甚至當餘下50wt·%為有機溶劑亦 如此。如果使用2 —丙醇或丙酮,則該水含量應高於75%, 以提高該閃點至20°C以上。 令人驚異地是,藉利用此類一發明性乾燥方法,該清 洗液可一次清除而不會在碟型物品上留下任何液滴。 15 該乾燥方法不僅能夠乾燥半導體晶圓之親水性表面, 而且能夠乾燥疏水性表面,而且也能夠乾燥具有親水性及 疏水性區域之結構化表面。 _ 不束縛於任何理論,但相信該清洗承在該表面上形成 可不容易被去除之一液膜(液體彎月面)。將氣體吹到該液膜 20 上部分打開該液層。接著,因包含水和該物質的該混合物 之比表面能之故,清洗液會在僅僅是微小的額外支助(例如 重力、離心力、氣流、毛細管力)下,自動流離該表面。但 是,進一步將氣體吹到該表面上可會有幫助,以保持該表 面與液體分離。
7 上’這表示該等液體和氣體自低處被供應至該晶圓。作為 選擇,藉利用該相同方法’例如具有如us 6,536,454Β2所揭 示之一旋轉卡盤,該晶圓兩面可同時被乾燥。 I:圖式簡單説明:| 第1圖至第4圖顯示該等上述示例。 在第1圖中,該清洗液透過液體配注件1被配注至一旋 轉晶圓W上《氣體配注件2位於等待位置。清洗液完全覆蓋 該晶圓並因此形成該液層L。 在第2圖中’氡體被吹動透過氣體配注件2並因此打開 位於一微小中央區Α内之該液層。液體配注同時停止且液體 配注件1被放置進備用位置。 在第3圖中顯示大約1〇s之一時間後之情形。該乾燥區 域自動變大《氣, 在第4圖中, 氣體仍舊被配注(但是非必需)。 【主要元件 1…液體配注件 2···氣體配注件 A…微小中央區 現在該晶圓表面被完全乾燥。 t将號說明】 L…液層 W…旋轉晶圓
