Patent ID: 7851327

Claim:
A method of manufacturing a semiconductor device, comprising: partially removing a first insulation layer from a first area of a semiconductor substrate, thereby forming an opening defining a first active region of the first area of the substrate and forming a first insulation pattern including a residual first insulation layer surrounding the opening; forming a first active pattern on the first active region of the first area of the substrate by filling the opening with first single-crystalline semiconductor material, thereby transforming the first insulation pattern surrounding the first active pattern into a first device isolation pattern on the first area of the substrate; partially removing a semiconductor layer comprising second single-crystalline semiconductor material from the second area of the substrate, thereby forming a recessed portion through which a second field region defining a second active region on the second area of the substrate is formed and forming a second single-crystalline semiconductor pattern including a residual semiconductor layer surrounding the recessed portion; and forming a second device isolation pattern on the second field region of the second area of the substrate by filling the recessed portion with a second insulation layer, thereby transforming the second single-crystalline semiconductor pattern surrounding the second device isolation pattern into a second active pattern on the second area of the substrate.
