    摘要: A method of forming a semiconductor device, where the method may include forming a first trench in a semiconductor substrate, forming first device isolation patterns that fill the first trench, forming spacers on sidewalls of the first device isolation patterns, forming a second trench in the semiconductor substrate between first device isolation patterns, and forming second device isolation patterns that fill the second trench. The second trench is formed using an etching process adopting the first device isolation pattern and the spacer as a mask.
