對晶圓全面照射波長172nm光,形成保護膜(膜厚90nm)。
又,將在上述矽基板上所製作而得之保護膜於同表所示之溫度浸漬於下述表2所示之組成的鹼性過氧化氫水溶液(在下述表1中,略稱為APM。)中,計測該保護膜從矽基板剝落為止之時間,評估APM耐性。將該結果示於表1。表1中,“○”表示在浸漬10分鐘時未觀察到上述阻劑下層膜剝落之狀態,“×”表示在浸漬10分鐘時在上述阻劑下層膜的一部分或全部觀察到剝落之狀態。
由上述表1之結果,使用實施例1及實施例2、比較例1中所調製而得之保護膜形成組成物所製作而得之保護膜係呈現僅在熱硬化下顯示出針對於阻劑溶劑之耐溶劑性之結果。在另一方面,使用比較例2及比較例3中所調製而得之保護膜形成組成物所製作而得之保護膜係呈現僅在光硬化下顯示出針對於阻劑溶劑之耐溶劑性之結果。
此外,如表1所示,使用於本發明之保護膜形成組成物之樹脂相比於比較例2及比較例3中所調製而得之保護膜形成組成物而言係呈現APM耐性優異之結果。
再者,使用於本發明之保護膜形成組成物之樹脂相比於比較例1中所調製而得之保護膜形成組成物而言係呈現保存安定性優異之結果。此被認為是比較例1中所調製而得之保護膜形成組成物係保存安定性較差,交聯並未充分地進行,並未表現出APM耐性。
[產業上之可利用性]
本發明所涉及之保護膜形成組成物係提供在基板加工中應用濕蝕刻液時耐性優異的保護膜。
