Description
本發明係關於曝光時作為抗反射膜而發揮功能,而且可埋入狹窄間隙及高長寬比之凹部的阻劑下層膜,及用以形成對過氧化氫水溶液之耐性優良的阻劑下層膜(保護膜)之組成物。進而係關於應用前述阻劑下層膜形成圖型之方法。
已知有於基板與形成於其上的阻劑膜之間設置阻劑下層膜,形成所期望之形狀的阻劑圖型之微影術製程。但是,以往的阻劑下層膜,例如下述專利文獻1記載之由含有胺基樹脂(aminoplast)系交聯劑的組成物所形成之阻劑下層膜,對過氧化氫水溶液之耐性不良。因此,無法將如此之阻劑下層膜,使用作為利用過氧化氫水溶液之濕式蝕刻製程中的遮罩。
下述專利文獻2中,記載含有具有經保護之羧基的化合物、具有可與羧基反應之基的化合物,及溶劑之微影術用下層膜形成組成物;或含有具有可與羧基反應之基與經保護之羧基的化合物,及溶劑之微影術用下層膜形成組成物,該組成物不含有胺基樹脂系交聯劑作為必須成分。但是專利文獻2中毫無記載或暗示由該組成物所形成之阻劑下層膜對過氧化氫水溶液之耐性。
下述專利文獻3中,記載使用具有對鹼性過氧化氫水溶液之耐性的阻劑下層膜之圖型形成方法。此外,用以形成該阻劑下層膜之組成物,含有重量平均分子量1000至100,000之具有環氧基之聚合物,及溶劑。
下述專利文獻4中,記載使用於構造單位中具有至少1個硫原子的聚合物之阻劑下層膜形成組成物。於半導體元件之製造中,使用於表面具有凹部的基板時,必須有可埋入該基板之凹部的間隙填充材或平坦化膜。但是,專利文獻4中,毫無記載或暗示凹部之埋入性。
下述專利文獻5中,記載使用於主鏈具有三嗪環及硫原子的共聚物之阻劑下層膜形成組成物。藉由使用專利文獻5記載之組成物,可得到曝光時作為抗反射膜而發揮功能,且可埋入半導體基板之孔洞(直徑0.12μm、深度0.4μm)的阻劑下層膜。 [先前技術文獻] [專利文獻]

以下說明使用本發明之阻劑下層膜形成組成物之圖型形成方法。 藉由本發明之圖型形成方法,可於半導體基板之表面或半導體基板上之無機膜等形成圖型。
塗佈本發明之阻劑下層膜形成組成物之半導體基板,例如可列舉矽基板、鍺基板,及砷化鎵、磷化銦、氮化鎵、氮化銦、氮化鋁等之化合物半導體晶圓。使用表面形成有無機膜之半導體基板時,該無機膜例如係藉由ALD(原子層沈積)法、CVD(化學氣相沈積)法、反應性濺鍍法、離子鍍法、真空蒸鍍法、旋轉塗佈法(旋塗式玻璃:SOG)而形成。前述無機膜例如可列舉多晶矽膜、氧化矽膜、氮化矽膜、BPSG(Boro-Phospho Silicate Glass)膜、氮化鈦膜、氮化氧化鈦膜、鎢膜、氮化鎵膜,及砷化鎵膜。
於具有凹部之上述基板之上,藉由旋轉器、塗佈器等之適當的塗佈方法塗佈本發明之組成物,之後,使用加熱板等之加熱手段進行烘烤,藉以形成阻劑下層膜。烘烤條件係由烘烤溫度80℃至350℃、烘烤時間0.3分鐘至10分鐘當中適當選擇。較佳為烘烤溫度120℃至300℃、烘烤時間0.5分鐘至5分鐘。此處,阻劑下層膜之膜厚,係0.005μm至3.0μm,例如0.01μm至0.1μm,或0.05μm至0.5μm。
烘烤時之溫度較上述範圍低時交聯變得不充分,所形成之阻劑下層膜可能難以得到對阻劑溶劑或過氧化氫水溶液的耐性。另一方面,烘烤時之溫度高於上述範圍時,阻劑下層膜可能因熱而分解,與該阻劑膜引起互混。
接著於前述阻劑下層膜之上形成阻劑膜。阻劑膜之形成,可藉由一般的方法,亦即光阻溶液之對阻劑下層膜上之塗佈及烘烤來進行。
前述阻劑膜之形成所使用的光阻溶液,只要係對曝光所使用之光源感光者則無特殊限定,負型、正型均可使用。
形成阻劑圖型時,係通過用以形成該阻劑圖型之特定圖型的遮罩(倍縮光罩)來進行曝光。曝光例如可使用KrF準分子雷射、ArF準分子雷射。曝光後係依需要進行曝光後加熱(Post Exposure Bake)。“曝光後加熱”之條件,係由加熱溫度80℃至150℃、加熱時間0.3分鐘至10分鐘當中適當選擇。之後,經以鹼顯影液顯影之步驟,形成阻劑圖型。
前述鹼顯影液,可列舉如氫氧化鉀、氫氧化鈉等之鹼金屬氫氧化物之水溶液;氫氧化四甲基銨、氫氧化四乙基銨、膽鹼等之氫氧化四級銨之水溶液;乙醇胺、丙胺、乙二胺等之胺水溶液之鹼性水溶液。進一步地,亦可於此等顯影液中添加界面活性劑等。顯影之條件,係由顯影溫度5℃至50℃、顯影時間10秒至300秒適當選擇。
接著,以所形成之阻劑圖型為遮罩,將前述阻劑下層膜進行乾式蝕刻。此時,於所用之半導體基板表面形成有前述無機膜時,係使該無機膜之表面露出,於所用之半導體基板表面未形成前述無機膜時,係使該半導體基板之表面露出。
進一步地,以乾式蝕刻後之阻劑下層膜(於該阻劑下層膜上殘存有阻劑圖型時,該阻劑圖型亦)為遮罩,藉由使用過氧化氫水溶液進行濕式蝕刻,形成所期望之圖型(例如,於所用之半導體基板表面形成有前述無機膜時,可於該無機膜形成所期望之圖型,又,於所用之半導體基板表面未形成前述無機膜時,可於該半導體基板表面形成所期望之圖型)。濕式蝕刻之藥液,可列舉顯示鹼性之物質,例如氨、氫氧化鈉、氫氧化鉀、氰化鈉、氰化鉀、將三乙醇胺等之有機胺與過氧化氫水混合使pH成為鹼性之鹼性過氧化氫水溶液,及將鹽酸、硫酸等之無機酸與過氧化氫水混合而得的酸性過氧化氫水溶液。其他,可使pH成為鹼性者,例如藉由將脲與過氧化氫水混合並加熱而引起脲之熱分解以產生氨,最終使pH成為鹼性者,亦可作為濕式蝕刻之藥液使用。鹼性過氧化氫水溶液及酸性過氧化氫水溶液之使用溫度較期望為25℃至90℃、更期望為40℃至80℃。濕式蝕刻時間較期望為0.1分鐘至30分鐘、更期望為0.5分鐘至15分鐘。 [實施例]

膜之矽晶圓(以下,本說明書中略稱為SiO2
晶圓)上。之後,於加熱板上以上述表1所示溫度烘烤1分鐘,形成阻劑下層膜(膜厚0.2μm)。
再者,圖2表示本試驗中使用之SiO2
晶圓4及對該晶圓所形成之下層膜3的示意圖。該SiO2
晶圓4具有溝槽之Dense(密集)圖型,該Dense圖型,係自溝槽中心至相鄰之溝槽中心為止的間隔為該溝槽寬度之10倍的圖型。如圖2所示,SiO2
晶圓4之溝槽的深度1為0.23μm、溝槽的寬度2為0.01μm。

晶圓上形成阻劑下層膜時,於溝槽部未觀察到孔隙(間隙),且觀察到溝槽內部係被該阻劑下層膜填充,溝槽全體完全被埋入。但是,使用比較例1及比較例2之阻劑下層膜形成組成物於SiO2
晶圓上形成阻劑下層膜時,於溝槽部觀察到孔隙(間隙),該溝槽內部未被阻劑下層膜填充,觀察到溝槽全體未完全被埋入。表1中,“○”表示於前述溝槽部未觀察到孔隙之狀態,“×”表示於前述溝槽部觀察到孔隙之狀態。

又,使用實施例1至實施例12中調製之阻劑下層膜形成組成物所製作之阻劑下層膜,顯示對鹼性過氧化氫水溶液具有充分的耐性。亦即,可知此等之塗膜,可成為對鹼性過氧化氫水溶液之保護膜。另一方面,使用比較例1及比較例2中調製之阻劑下層膜形成組成物所製作之阻劑下層膜,顯示不具有對鹼性過氧化氫水溶液之耐性,明顯可知此等之塗膜,無法成為對鹼性過氧化氫水溶液之保護膜。
進一步地,使用實施例1至實施例12中調製之阻劑下層膜形成組成物於SiO2
晶圓上所製作之阻劑下層膜,於溝槽部未觀察到孔隙(間隙),且觀察到溝槽內部被阻劑下層膜填充,溝槽全體完全被埋入。另一方面,使用比較例1及比較例2中調製之阻劑下層膜形成組成物所製作之阻劑下層膜,於溝槽部觀察到孔隙(間隙),溝槽內部未被阻劑下層膜填充,溝槽全體未完全被埋入。
