    摘要: Methods of forming a semiconductor device include forming a trench mask pattern on a semiconductor substrate having active regions and device isolation regions. A thermal oxidation process is performed using the trench mask pattern as a diffusion mask to form a thermal oxide layer defining a convex upper surface of the active regions. The thermal oxide layer and the semiconductor substrate are etched using the trench mask pattern as an etch mask to form trenches defining convex upper surfaces of the active regions. The trench mask pattern is removed to expose the convex upper surfaces of the active regions. Gate patterns are formed extending over the active regions.

    摘要: Patterns are formed in a semiconductor device by defining a lower layer that includes a first region and a second region on a semiconductor substrate, forming first patterns with a first pitch that extend to the first and second regions, forming second patterns with a second pitch in the second region that are alternately arranged with the first patterns, forming a space insulating layer that covers the first and second patterns and comprises gap regions that are alternately arranged with the first patterns so as to correspond with the second patterns, forming third patterns that correspond to the second patterns in the gap regions, respectively, etching the space insulating layer between the first and second patterns and between the first and third patterns, such that the space insulating layer remains between the second patterns and the third patterns, and etching the lower layer using the first, second, and third patterns and the remaining space insulating layer between the second and third patterns as an etching mask.
