Description
技术领域
本发明涉及在具有-HSiRO-(R表示氢原子、碳原子数为1~8的烃基、碳原子数为1~8的烷氧基或苯氧基)的硅氧烷化合物中加入特定的苯酚化合物作为稳定剂的组合物。该组合物适合用作薄膜制造用原料。
背景技术
具有-HSiRO-(R表示氢原子、碳原子数为1~8的烃基、碳原子数为1~8的烷氧基或苯氧基)的硅氧烷化合物被用作氧化硅类薄膜的前体,并且从其电特性和光学特性出发,该氧化硅类薄膜被用作半导体的多层配线之间的低介电常数绝缘膜、显微透镜等光学零件。
但是,上述硅氧烷化合物在使用时,存在的问题是因高分子化而产生的变质。例如,在包含溶胶凝胶法的湿式涂敷法中,由于涂敷液的粘度增加或凝胶化,存在不能制造稳定的薄膜的问题,在伴有气化的薄膜制造法中,难以使前体以恒定量稳定地进行气化,另外还存在由高分子化物而引起的装置或薄膜的污染、以及管道堵塞的问题。
对于上述问题,在专利文献1中,报道了与硅氧烷化合物一起使用2,6-二叔丁基-4-甲基苯酚等苯酚化合物的方法,在专利文献2中,报道了与硅氧烷化合物一起使用以4-甲氧基苯酚为代表的苯酚化合物的方法。
但是,这些以往的苯酚化合物的稳定化效果不充分。
