Abstract
Disclosed is a semiconductor device including: a semiconductor substrate; first and second element isolating trenches that are formed in one main surface of the semiconductor substrate separately from each other; a first insulating material that is formed within the first element isolating trench; a plurality of first element formation regions that are surrounded by the first element isolating trench; first semiconductor elements that are respectively formed in the first element formation regions; a second insulating material that is formed within the second element isolating trench; a second element formation region that is surrounded by the second element isolating trench; a second semiconductor element that is formed in the second element formation region; and a stress relaxation structure that is formed between the first element isolating trench and the second element isolating trench.
