Description
本發明係關於一種用於去除附著於半導體基板表面之物質之淸潔溶液,及一種使用此溶液之方法。更特別地,本發明係關於一種可去除堅固地附著於半導體基板表面之物質而不損壞半導體基板上之金屬線路及層間絕緣膜之淸潔溶液,及一種使用此溶液之方法。
目前通常使用微影術作為製造半導體裝置(如高整合LSI)之方法。在依照微影術製造半導體裝置時,此製法通常依照以下系列之步驟。在基板(如矽晶圓)上形成作為線路之導電性材料之導電性薄膜(如金屬膜)、及用於使導電性薄膜與線路間絕緣之層間絕緣膜(如氧化矽膜)。然後將得到之基板表面均勻地塗覆光阻劑以形成感光層,及藉選擇性曝光及顯影處理而在光阻劑上形成所需圖樣。使用形成之光阻圖樣作為光罩,選擇性地蝕刻光阻層下之薄膜,及經此光阻圖樣在光阻層下之薄膜上形成所需圖樣。然後將光阻圖樣完全地去除。
近來,半導體為高整合,而且需要形成0.18微米或更細之圖樣。隨此作業之尺寸變小,乾燥蝕刻變成用於選擇性蝕刻處理之主要方法。在乾燥蝕刻處理中,已知衍生自乾燥蝕刻氣體、光阻劑、作業膜、及乾燥蝕刻裝置之槽中材料之殘渣(以下將這些殘渣稱為蝕刻殘渣)在此處理形成之圖樣周圍之部份形成。在蝕刻殘渣殘留於通路孔內部
及周圍之部份時,有引起如電阻增加及電短路之不欲現象之可能。
迄今,作為用於在半導體裝置中形成金屬線路之步驟中去除蝕刻殘渣之淸潔溶液,例如,由烷醇胺與有機溶劑之混合系統組成之有機胺系去除溶液,揭示於日本專利申請案公開第昭和62(1987)-49355與昭和64(1989)-42653號。
在使用此有機胺系去除溶液時,由於在去除蝕刻殘渣與光阻劑後以水淸洗時吸收之水分造成去除溶液中發生胺之解離。此溶液變成鹼性,結果,有可能腐蝕,作為用於線路精細作業之材料之薄膜金屬。如此造成必須使用有機溶劑(如醇)作為淸洗液體以防止腐蝕之問題。
至於相較於有機胺系去除溶液呈現較優良之去除蝕刻殘渣與硬化光阻層能力之淸潔溶液,由氟化合物、有機溶劑與腐蝕抑制劑組成之氟系淸潔溶液揭示於日本專利申請案公開第平成7(1995)-201794與平成11(1999)-67632號。然而,由於近來製造半導體裝置之方法中之較嚴格乾燥蝕刻條件,光阻劑本身趨於在乾燥蝕刻溫度因用於乾燥蝕刻之氣體而降解,及以以上之有機胺系去除溶液或以上之氟系水溶液完全去除蝕刻殘渣變為困難的。
由於含鋁作為主要成分之材料(其迄今已經常作為線路材料)製成之電路之大電阻,在高速適當地作業變為困難的,而且逐漸僅使用銅作為線路材料。因此,製造有效地去除蝕刻殘渣而不損壞線路材料之具優良品質之半導體
裝置為重要的。
含大量有機溶劑之有機胺系淸潔溶液及氟系淸潔溶液因對環境之大量努力而造成問題,如需要確保廢液之安全性及處理,而且克服此問題之手段變為重要的。例如,一種酸系淸潔劑(其為有機酸之水溶液)揭示於日本專利申請案公開第平成10(1998)-72594號,及一種酸系淸潔劑(其為硝酸、硫酸與磷酸之水溶液)揭示於日本專利申請案公開第2000-338686號。然而,這些淸潔劑呈現不足以去除越來越堅固之蝕刻殘渣(特別是含層間絕緣膜成分之蝕刻殘渣)之能力。
因此,在製造半導體裝置之方法中,已需要可完全地去除蝕刻殘渣而不損壞線路材料,提供製造半導體裝置之方法之安全性,及對環境呈現極小之負面影響之淸潔溶液。
本發明之目的為提供一種淸潔溶液,其可在將用於半導體積體電路之半導體裝置或顯示裝置接線之步驟中之乾燥蝕刻後,或在將半導體基板乾燥蝕刻後,在短時間內去除殘留之蝕刻殘渣,而不氧化或腐蝕銅線路與絕緣膜之材料,及一種使用此淸潔溶液淸潔具金屬線路之半導體裝置、顯示裝置與半導體基板之方法。
本發明人為了克服以上問題而深入研究之結果,發現藉由組合使用氧化劑、酸、氟化合物、鹼性化合物、與腐蝕抑制劑,可得到優良之淸潔溶液。

應用本發明淸潔溶液之半導體基板之實例包括具有金屬線路材料之半導體基板,如矽、非晶矽、多矽、氧化矽膜、氮化矽膜、銅、鈦、鈦-鎢、氮化鈦、鎢、鉭、鉭化合物、鉻、氧化鉻、與鉻合金;具有複合半導體之半導體基板,如鎵-砷、鎵-磷與銦-磷;印刷基板,如聚醯亞胺樹脂之印刷基板;及用於LCD之玻璃基板。
本發明之淸潔溶液可有效地用於,例如,以上之半導體基板、具僅銅或銅與屏障金屬(界面金屬層)之層合結構使得具金屬線路之半導體裝置或顯示裝置中之電路可以高速作業之半導體基板。
在必要之處,本發明之淸潔方法可組合超音波淸潔進行。對於已去除具金屬線路之半導體裝置、顯示裝置或半導體基板上之蝕刻殘渣後之淸洗,可使用如醇之有機溶劑或醇與超純水之混合物。然而,依照本發明之淸潔方法,
僅以超純水淸洗為足夠的。
本發明參考以下之實例及比較例而更特定地敘述。然而,本發明不限於此實例。
第1圖顯示呈現半導體裝置之一部份切面之圖表。此半導體裝置係如下而得:藉由依照CVD法沈積於下層之銅線1上而連續地形成氮化矽膜2與氧化矽膜3;將形成之層合物塗覆光阻劑;依照習知照相技術將光阻劑加工;使用乾燥蝕刻技術將氧化矽膜蝕刻而具有所需之圖樣;及去除殘餘光阻劑。如第1圖所示,蝕刻殘渣仍殘留於蝕刻形成之壁上。
將以上銅電路裝置以表1至8所示之淸潔溶液在表中所示之條件下淸潔,以超純水淸洗及乾燥。然後使用掃描電子顯微鏡(SEM)觀察表面條件,而且評估蝕刻殘渣去除及銅腐蝕之情況。評估結果示於表1至4及表5至8。
評估標準示於以下。
(1)蝕刻殘渣去除
優良:蝕刻殘渣完全地去除。
良好:蝕刻殘渣幾乎完全地去除。
尚可:殘留一部份蝕刻殘渣。
不良:殘留大部份蝕刻殘渣。
(2)銅腐蝕
優良:完全未發現腐蝕。
良好:幾乎未發現腐蝕。
尚可:發現坑洞形狀或穴形之腐蝕。
不良:在銅層之全部表面上發現「粗化」,及發現銅層變薄。
如表1與2所示,在其中應用本發明之清潔溶液及清潔方法之實例1至9中,完全未發現腐蝕,及蝕刻殘渣去除完全。如表3與4所示,在所有之比較例1至7中,蝕刻殘渣去除不完全或發現銅腐蝕。
如表5與6所示,在其中應用本發明之清潔溶液及清潔方法之實例10至18中,未發現銅腐蝕,及蝕刻殘渣去除優良。如實例12所示,即使是在相較於實例11為較高之溫度進行清潔較長之時間時,亦未發現銅腐蝕。相反地,在未加入聚乙亞胺(腐蝕抑制劑)時(比較例9),發現銅腐蝕。在所有之比較例8至14中,蝕刻殘渣去除不完全或發現銅腐蝕。
本發明之蝕刻溶液安全且對環境呈現極小之負面影響。由於半導體基板上之蝕刻殘渣可藉由使用本發明之淸潔溶液易於在短時間內去除,半導體基板之精密作業完全可行而不腐蝕線路材料。此外,使用有機溶劑(如醇)作為淸洗液體為不必要的,及淸洗可僅以水進行。因此,具高精確度及高品質之電路線路製造可行。
1‧‧‧下層之銅線
2‧‧‧氮化矽膜
3‧‧‧氧化矽膜
4‧‧‧蝕刻殘渣
第1圖顯示呈現半導體裝置之一部份切面之圖表,其係藉由沈積於下層之銅線上而形成氮化矽膜與氧化矽膜,繼而為蝕刻處理及去除殘餘光阻劑而得。
