Description

200540864 九、發明說明： 【發明所屬之技術領域】 本發明係關於光學資料儲存媒體，特別關於如 DVD-14/18、DVD R DL與其他多層媒體之光碟的製造。 【先前技術】 一般用來製造雙層單面DVD (如DVD-9)的方法爲黏 結2片0.6mm基板在一起，其中每一片係載有一資訊層。用 來製作雙層碟片之其他方法爲所謂”2P製程”。該2P製程將 ® 雙層單面（單層於每一片基板）提升爲具有雙層內部資訊層 之單一基板構造。其對於DVD-9之製造並不需要，但對於 其他如DVD 14/1 8或DVDR9的多層格式則爲必要的。 相關技術
美國專利第6，1 17,284號與6,309,496號說明關於該2P 製程之一般資訊。 在2P製程之第一步驟中，藉由射出成形製造具有資訊 層之第一基板並以適用之層形材料來塗布。然後製造具有第 ®二資訊層之第二基板，通常使用一種紫外線硬化黏著劑來黏 結該第二基板與第一基板。於下一步驟中，分離該2片（已 黏結）之基板，因而第二基板之資訊層影像必定會完全留存 在第一基板上。隨施作之不同，亦可能以相似方法將第二層 金屬層移轉至第一層基板。 爲了良好之壓印結果與容易之分離目的，UV硬化黏著 劑與第二基板之材料選擇爲重要的。然而通常使用聚碳酸酯 於第一基板，而使用PMMA或其他非極性材料於第二基板。 200540864 然而，於第一與第二基板間所使用二 須滿足許多要求。一方面該材料應提供$ 一方面該材料應於分離程序後使第一基 械應力，以避免該基板之彎曲。由於通常 縮程序而無法避免某些應力之發生。 爲克服使用單一硬化黏著劑來達成 最小化的困難，該黏結層可使用2種不同 布一種具有最佳化之彈力性質黏著劑於養 β 塗布第二種已對於複製性質最佳化之i 上。其中應以第一與第二黏著劑之厚度比 須藉最大化第一黏著劑厚度來避免第二 增加厚度而增加之基板彎曲之所導致的景 用於DVD R DL媒體之黏結層所需之厚J! 由提供40μπι之第一黏著劑於第一基板上 著劑於第二基板上並使其黏結在一起來· 圖）。 ^ 在本工藝之說明的實驗中，如 6,1 3 6,1 33號公報中所述，同時使用該2 板上，然後藉由一硬化步驟將其黏結在一 些許的製程步驟，但是具有某些缺點。當 厚度之第一與第二黏著劑時，則難以達成 度與碟片外緣清潔度之要求。 【發明內容】 爲了避免使用兩種不同黏著劑之2Ρ :UV硬化黏著劑必 :好之壓印結果，另 板上受到最小的機 在硬化期間發生收 良好之複製與彎曲 丨黏著劑來製造。塗 I 一基板之上，並且 注著劑於第二基板 ;例不對等爲佳。必 黏著劑對於其隨著 >響。提出一範例： 変爲50μιη，其可藉 .及1 Ομπι之第二黏 ί造（本例參照第1 例如美國專利第 種黏著劑於該等基 起。該方法雖僅需 使用具有顯著不同 黏結程序中高信賴 製程技術的缺點， 200540864 提出以下之方法。旋轉塗布一種以具有良好複製性質爲佳之 第一黏著劑於適當基板之上並於第一硬化步驟中以UV光線 硬化之。於下一步驟中，使用第二黏著劑將該已塗布之基板 與其他基板黏結在一起。該步驟係以一種第二硬化步驟結束 之標準黏結步驟。 【實施方式】 藉助於第2圖來詳細地顯示一個較佳實施例。一種用於 製造碟形工作部件之發明方法包含製造第一與第二碟形基 g板、塗布第一黏著劑1於該第一基板2之至少部份平面側 上、硬化該第一黏著劑、塗布第二黏著劑3於該第一基板2 或第二基板4之至少之一平面側之至少部份上、與黏結該等 基板而形成該碟形工作部件5的步驟。然後碟形工作部件可 再次進行硬化。 本發明將製備複合黏結層之製程分爲塗布程序與黏結 程序之二個可被良好控制之步驟。該製程不但將解決與現行 方法相關製程之問題，同時亦將提高黏結程序之信賴度與所 完成之碟片的外緣清潔度。 •【圖式簡單說明】 第1圖係顯示一種黏結程序之先前技術的狀況。 第2圖係顯示本發明製程之一實施例。 【元件符號說明】 1 第一黏著劑 2 第一基板 3 第二黏著劑 4 第二基板 5 已黏結狀態之碟形工作部件
