    摘要: The present invention discloses to a method of forming an isolation layer in a semiconductor device. In particular, the method of forming an isolation layer in a semiconductor device of the present invention comprises the steps of providing a semiconductor substrate on which a trench is formed; forming spacers on side walls of the trench; forming a first insulating layer to fill a portion of the trench such that a deposition rate on the semiconductor substrate which is a bottom surface of the trench and exposed between the spacers is higher than that on a surface of the space; and forming a second insulating layer on the first insulating layer so as to fill the trench with the second insulating layer. An O3-TEOS layer on the exposed semiconductor substrate which is a bottom surface of the trench is grown faster than that on a surface of the spacer formed of an oxide layer or a nitride layer to prevent the O3-TEOS layers grown on the side walls from coming into contact with each other, and so it is possible to inhibit a generation of a seam and to enhance a gap-filling characteristic for the trench.

    摘要: A method of forming an isolation layer of a semiconductor device includes forming first trenches in an isolation region of a semiconductor substrate. Sidewalls and a bottom surface of each of the first trenches are oxidized by a radical oxidization process to form a first oxide layer. An oxidization-prevention spacer is formed on the sidewalls of each of the first trenches. Second trenches are formed in the isolation region below the corresponding first trenches, wherein each second trench is narrower and deeper than the corresponding first trench. The second trenches are filled with a second oxide layer. The first trenches are filled with an insulating layer.
