Abstract
本发明涉及一种深槽的填充方法及深槽的填充结构。上述深槽的填充方法包括如下步骤:提供具有至少一深槽的半导体衬底,深槽的深宽比小于或等于40;将绝缘件置于半导体衬底上,且绝缘件遮蔽深槽的开口,绝缘件的材质为聚合物材料;对绝缘件进行加热,使绝缘件呈液态;在真空条件下,对绝缘件加压,使液态的绝缘件填充于深槽内,然后固化,在深槽内形成绝缘层。上述深槽的填充方法在深槽内填充绝缘层仅需要几分钟至十几分钟,较传统的化学气相沉积的方法(需要几十个小时)大大节省了沉积时间,提高了生产效率。且以聚合物材料为绝缘件的材料,较传统的以二氧化硅为绝缘层,介电常数相差不大,甚至部分高于二氧化硅,绝缘性好。
