    摘要: Disclosed is a method for forming an isolation layer of a semiconductor device. The method includes the steps of providing a semiconductor substrate having a predetermined isolation region, sequentially forming a pad oxide layer and a pad nitride layer exposing the predetermined isolation region on the semiconductor substrate, forming a trench through etching the semiconductor substrate by a predetermined thickness using the pad nitride layer as a mask, forming a wall oxide layer at a side wall of the trench, sequentially forming a nitride layer and an oxide layer on a trench structure including the wall oxide layer, forming an Al2O3 layer on an entire surface of a resultant structure, planarizing the Al2O3 layer through polishing the Al2O3 layer, and forming the isolation layer by removing the pad nitride layer.
