Description

形成二氧化矽基層的組成物及製造二氧化矽基層的方法 【相關申請案之交互參照】
本申請案主張2014年5月26日在韓國專利局所申請的韓國專利申請案第10-2014-0063293號的優先權與利益,其全部內容藉由參照而併入至本申請案中。
本發明是有關於一種形成二氧化矽基層的組成物以及製造二氧化矽基層的方法。
由於半導體技術的加速發展,在高積集度與高速半導體記憶胞的研發上,已經進行了:藉由增加具有更小尺寸的半導體晶片的積集度而提升效能。這些半導體記憶胞中,例如,可使用動態隨機存取記憶體(DRAM)。DRAM能夠隨意地輸入和輸出資訊,並且可實現大容量。
DRAM可以包含:例如,多個單元胞,此單元胞包含一個MOS電晶體與一個電容。電容可以包含:兩個電極與一個位在兩電極間的介電層。此電容可以依照例如介電常數、介電層的厚度、電極面積等等而得到各種電容值。
當半導體晶片的尺寸減小時,其中的電容尺寸也會隨之減小。然而,這較小的電容仍需要有足夠的儲存容量。例如,藉由增加垂直面積替代減少水平面積以增加整體的主動區,可以使電容具有更大的電容量。當這個方法被用於製造電容時,可使用藉由使用鑄模(mold)且在鑄模上的間隙中填入用以形成二氧化矽基層的組成物所形成的二氧化矽基層,以有效地形成比窄的水平面積相對高的電極。
本發明的一實施例提供一種用以形成能夠極小化缺陷(defect)的二氧化矽基層的組成物。
本發明的另一實施例提供一種利用用以形成二氧化矽基層的組成物來製造二氧化矽基層的方法。
根據本發明的一實施例,提出一種用以形成二氧化矽基層的組成物,包括:含有氫化聚矽氮烷(polysilazane)、氫化聚環氧矽氮烷(polysiloxazane)或是它們的組合的二氧化矽基化合物;以及溶劑;其中,具有約0.2μm到約1μm粒子直徑的粒子的數目是少於或等於10/Ml
粒子的數目可以少於或等於約8/Ml
二氧化矽基化合物可以包括:含有以下面的化學式1表示的部份(moiety)的氫化聚矽氮烷。

以乾氮氣取代配備有攪拌器與溫度控制器的2公升(2L)反應器的內部。接著,將1,500g的乾砒啶注入到反應器,且反應器保溫在5℃。然後,以超過2小時的時間,緩慢注入140g的二氯矽烷。之後,以超過4小時的時間緩慢注入85g的氨,同時攪拌反應器。接著,注入乾氮氣120分鐘,且去除殘餘在反應器中的氨。獲得的白色漿態產品在乾氮氣環境下,經由1μm鐵氟龍過濾器進行過濾,得到1,000g過濾後的溶液。然後,將1,000g的乾二甲苯加入過濾後的溶液,藉由使用旋轉的蒸發器將混合液中的二甲苯以砒啶取代重複3次,以將其固體濃度調整成20%,且得到的混合液以0.1μm鐵氟龍過濾器進行過濾。之後,將250g乾砒啶加入得到的氫化聚矽氮烷溶液中,且此混合液於100℃聚合,直到重量平均分子量達到約200,000時為止。
當聚合終止時,藉由使用旋轉的蒸發器將產品中的溶劑在30℃以二丁醚取代重複3次,以將其固體濃度調整成20%,且得到的混合液以0.1μm鐵氟龍過濾器進行過濾,獲得氫化聚環氧矽氮烷。
評估根據比較例1與範例1到範例6的氫化聚矽氮烷溶液的反應性(reactivity)與其中的粒子數目。以下述方法進行評估。
[TMAH反應性評估方法]
比較例1與範例1到範例6的溶液分別取3cc,以旋轉 塗佈機(MIKASA公司的產品MS-A200)將溶液滴到直徑8英吋的晶圓中心,並以1500rpm的轉速旋轉塗佈20秒,以及以75℃加熱與乾燥3分鐘。然後,使用反射光譜式薄膜厚度儀(reflection spectroscopic film thickness meter)與反射光譜式晶圓收縮儀(reflection spectroscopic wafer contraction meter)量測每一薄膜的厚度,之後,於將薄膜浸泡在四甲基氫氧化銨(tetramethyl ammonium hydroxide,TMAH)中1分鐘且以純水清洗後,再以反射光譜式薄膜厚度儀(K-MAC公司的產品ST-4000)量測一次。
根據下面的計算方程式1可得知反應性。
[計算方程式1]TMAH WER(TMAH濕蝕刻率(Wet Etch Rate,WER))=(以75℃烘烤3分鐘後與浸泡在TMAH中1分鐘後減少的薄膜厚度)/(重量平均分子量)(△Å/Mw)
[粒子數目評估]
溶液中的粒子數目是使用液態粒子計數器(Liquid Particle Counter,LPC)(RION公司的產品KS-42BF)計算。特別的是,根據比較例1與範例1到範例6的溶液分別取10ml,然後,以二丁醚(dibutyl ether,DBE)溶液清洗3次。之後,產出的溶液分別放入100Ml的瓶中,然後再清洗3次。接著,分別計算5次溶液的粒子數,且平均第3次到第5次的量測值。此處,粒子的尺 寸(粒子直徑)範圍從約0.2μm到1μm才是有效的計數對象。
評估結果顯示在下面的表1與圖10中。
圖10是顯示根據比較例1與範例1到範例6的每一氫化聚矽氮烷溶液中的粒子數目以及這些溶液分別形成的薄膜層的TMAH反應性結果的圖表。
參照表1與圖10,根據範例1到範例6的由每Ml包含小於或等於10個具有直徑約0.2μm到1μm的粒子的氫化聚環氧矽 氮烷溶液形成的薄膜層顯示相對低的TMAH反應性,因為氫化聚環氧矽氮烷溶液具有較大的分子量。
