Abstract
A method for forming an isolation structure in a semiconductor device includes preparing a semi-finished substrate including a trench. An oxide layer is formed over sidewalls of the trench. A multiple layer structure of liner layers is formed over the oxide layer. An insulation layer is formed over the multiple layer structure such that the insulation layer fills an inside of the trench. The insulation layer is planarized.
