    • There is provided a method of forming an element isolation structure that can maintain its element isolation capability even with the progress of miniaturization of semiconductor elements. Through thermal processing in a nitrogen atmosphere at 900° C., a non single-crystal silicon film (80) is crystallized into single-crystal form by epitaxial growth on the main surface of a substrate, thereby to form an epitaxial silicon film (85). The epitaxial silicon film (85) is then planarized by CMP to expose the upper surface of an element isolation insulating film (50). This completes the element isolation insulating film (50) having a two-level protruding shape.

    • PURPOSE: A method is provided to easily form an SOI(silicon on insulator) region as well as to form isolated silicon islands having low stress on a substrate. CONSTITUTION: A first dielectric region(44) is formed with a first dielectric material on a silicon substrate. Then, a silicon region(64) having the upper surface on the first dielectric region is formed on the first dielectric region. Herein, the silicon region is deposited on the upper surface of the first dielectric region. Moreover, a second dielectric region(80) is formed with a second dielectric material around the silicon region. Herein, the second dielectric region has an upper surface and a lower surface. The upper surface shares the upper surface of the silicon region, and the lower surface is spread over the same space with the peripheral region of the upper surface of the first dielectric region. Therefore, an SOI region is completed.
