574104 ⑴ 玖、發明說明 技術領域 本發明係關於一種矽酮樹脂,包含5至50莫耳%的 (PhSi〇(3-x)/2(OH)x)單元及 50 至 95 莫耳 % 的(HSi〇(3.x)/2(〇H)x),其中 Ph 為苯基,X具有〇、1或2的值,並且其中經固化的矽酮樹 脂具有的臨界表面自由能為30達因/公分或更高。這些樹 脂被用做具有臨界表面自由能為40達因/公分或更高之有 機介電物質的姓刻終止層。
先前技術 半導體裝置通常具有一或多個成型互相連接層的陣列 ,其用來電子偶合形成積體電路(1C)的各別電路元件。該 互相連接層一般是由絕緣或介電塗層分離。該塗層可以化 學蒸氣沉積或以旋轉上(spin-on)的技術形成。例如:美國專 利4,756,977號揭示氫化倍半氧石夕燒(Hydrogen silsesquioxane)樹脂 的用途,以在電子裝置上形成塗層。 形成積體電路的一個方法已知為雙重波紋。此方法牽涉 到塗覆一層介電質、蝕刻線路型態到介電質上、以線路金 屬填充該型態、並且重覆該製程,直到形成所要數目的層 數0 變得有利的是使用至少兩種具有不同蝕刻特性的不同 物質,以產生介電層。在本質上,一個介電屬當做另一個 介電層之钱刻的钱刻終止物。較佳的是介電層之一為有機 物質,而另一個是無機物質,以增進物質之間的触刻選擇 性。一個介電層可當做對另一個的蝕刻終止物。在氧為基 礎的電漿中,有機介電層趨向於比無機介電層更快蝕刻。 574104 _ (2) 發明說明續頁 在碳氟基礎的電漿中,無機介電層趨向於比有機介電層更 快敍刻。無機、有機、無機或有機、無機、有機的三明治 結構也在積體電路中被用做介電層。 頒發給應用訊息(Allied Signal)的PCT專利申請WO 01/ 18861 A1 號揭示具有基材的微電子裝置、及位於基材上的一層第一 電子介電層材質。第二介電層材質層位於第一介電層上, 並且另一層第一介電層材質位於第二介電層上。有機介電 層為包含碳的材質,並且無機介電層為不包含碳的材質。 美國專利6,218,317號揭示甲基化氧化物類硬光罩在聚合 層間(interlayer)介電材質上的形成,具有介電常數低於3,並 且更佳2.7或更低。 當使用兩或多個介電層時,理想的是較上層的材質能夠 適當地塗覆較下層(即:濕潤該表面)。也理想的是具有在 層之間足夠的黏著力。 發明内容 本發明係關於矽酮樹脂,包含5至50莫耳%的(PhSiO(3.xV2(〇H)x) 單元及50至95莫耳%的(HSiO(3-x)/2(〇H)x),其中Ph為苯基,X具 有0、1或2的值,並且其中經固化的矽酮樹脂具有的臨界 表面自由能為30達因/公分或更高。這些樹脂被用做具有 臨界表面自由能為40達因/公分或更高之有機介電物質的 I虫刻終止層。 本發明也係關於一種積體電路裝置,具有有臨界表面自 由能為40達因/公分或更高之有機介電層、及從該矽酮樹 脂產生之具有臨界表面自由能為30達因/公分或更高的苯 574104 (3) 發明說明續頁 基化氧化物介電層,其中至少一個有機介電層表面接觸苯 基化氧化物介電層的表面。 實施方式 本發明係關於矽酮樹脂,包含5至50莫耳%的(PhSi〇〇x)/2(〇H)x) 單元及50至95莫耳%的(HSi〇(3_x)/2(OH)x)單元,以在樹脂中含 矽單元的總量為基礎,其中Ph為苯基,X具有0、1或2的 值。 該矽酮樹脂包含5至50莫耳%的(PhSi〇(3_x)/2(〇H)x)單元,另 為25至50莫耳%,另為30至45莫耳%。在矽酮樹脂中的更 高份量(PhSiO(3.x)/2(OH)x)單元造成在苯基化介電層中更高份 量的碳。此減少苯基化氧化物介電層與有機介電層之間的 蝕刻選擇性。另外,在最終薄膜中的更高碳份量造成苯基 化氧化物介電層對有機介電層的較低黏著力。 對具有做為介電層與有機介電層組合之用途的矽酮樹 脂而言,理想的是在經固化矽酮樹脂中具有臨界表面自由 能為30達因/公分或更高。在矽酮樹脂中(PhSi〇(3_x)/2(〇H)x)的 每1莫耳%增加,理論上在經固化樹脂中臨界表面自由能 增加0.31達因/公分。因此,在矽酮樹脂中更高份量的 (PhSi〇(3.x)/2(OH)x)單元為理想的,然而發現的是(PhSi〇(3.xV2(〇H)\) 單元的份量增加,經固化矽酮樹脂對有機介電層的黏著力 減少。較佳的是經固化碎自同樹脂具有臨界表面自由能範圍 為35至60達因/公分,更佳為35至45達因/公分。 矽酮樹脂的結構不被特定地限制。該矽酮樹脂可必要地 完全縮合或只被部分縮合。當矽酮樹脂被部分縮合時,在 574104 (4) 發明說明續頁 矽酮樹脂中低於40莫耳%的單元包含Si-〇H基團。更高份量 的這些單元會造成在樹脂中的不穩定性,並且形成膠狀物 。一般在矽酮樹脂中6至38莫耳%的單元包含Si-OH基團。 石夕酮樹脂具有重量平均分子量(Mw)範圍為500至40〇,〇〇〇, 並且較佳的範圍為500至100,000,另為700至10,000。 在此所用之矽酮樹脂可以下列示範、但不限於: (PhSi〇3/2)a(HSi03/2)d (PhSi03/ 2)a(PhSi02/ 2(0H)b(HSi03/ 2)d (PhSi03/ 2)a(PhSi〇2/ 2(OH)b(HSi〇3/ 2)d(HSi02/ 2(〇H)e (PhSi03/ 2)a(HSi03/ 2)d(HSi02/ 2(0H)e (PhSi03/ 2)a(PhSi02/ 2(OH)b(PhSiOI/ 2(0H)2)c(HSi03/ 2)d (PhSi03/ 2)a(PhSi02/ XOHMPhSiOr 2(OH)2)c(HSi〇3/ 2)d(HSi〇2/ 2(OH)e 其中 a〉0、b>0、c>0、d〉0、e>0、0.05<a+b+c<0.5、0.5Sd+eS〇. 95 ,且 b+ c+ eS 0.4。 該樹脂可以此藝中已知的方法產生。例如:該樹脂可以 頒發給撒卡摩托(Sakamoto)等人之美國專利5,762,697號所述 之苯基三烷氧基化與氫三烷氧基化矽烷混合物的水解及 縮合產生。另外,其可以經頒發給貝克(Becker)等人之美國 6,281,285及專利5,010,159號中所述之苯基三氯矽烷與氫三氯 矽烷的水解及縮合產生。 矽酮樹脂一般是在溶劑的存在下產生。在生產矽酮樹脂 當中’可使用不包含會參與反應之官能基的任何適當有機 或矽酮溶劑。該溶劑通常使用的份量為40至98重量百分 比’以溶劑及矽烷反應物的總重為基礎,另為7〇至90重量 574104 (5) 發明說明續頁 百分比。反應可以雙相或單相系統來進行。

形成矽酮樹脂的時間取決於許多因素,如:溫度、矽烷 反應物的種類及份量、和若存在之觸媒的份量。一般反應 時間是從幾分鐘至幾小時。習知此藝者能夠容易地決定完 成反應的所需時間。 接續於反應完成,觸媒可被選擇地被移除。移除觸媒的 方法已為此藝中熟知的,並且包括中和、汽提或水洗或其 組合。觸媒可負面影響矽酮樹脂的架上壽命,特別是當在 溶液中時,因此建議移除之。 在製造矽酮樹脂的製程中,在反應完成之後,揮發物可 在減壓下從矽酮樹脂溶液中被移除。此類揮發物包括醇副 -10- 574104 _ (6) 發明說明續頁 產物、過量的水、觸媒、鹽酸(氯基矽烷路徑)及溶劑。移 除揮發物的方法在此藝中為已知,並且包括例如:蒸餾。
接續於產生矽酮樹脂的反應,可進行許多可選擇的步騾 ,以獲得所要形式之矽酮樹脂。例如:該矽酮樹脂可以移 除溶劑而以固體形式被回收。溶劑移除的方法不重要,並 且許多方法在此藝中已熟知(例如:在熱及/或真空下蒸餾) 。一旦該矽酮樹脂以固體形式被回收,該樹脂可選擇地為 特別的用途再溶解於相同或另一個溶劑中。另外,若對最 終產物理想的是除了反應中所用之溶劑的一個不同溶劑 ,則溶劑的交換可以添加第二溶劑、並且經由例如蒸餾來 移除第一溶劑而完成。額外地,在溶劑中的樹脂濃度可以 移除一些溶劑、或添加額外份量的溶劑來調整。
