    摘要: A semiconductor device having a trench isolation layer in a semiconductor substrate is provided, wherein the trench isolation layer includes a silicon nitride liner, a silicon oxide liner; and a buried layer, wherein the buried layer includes a first buried layer for filling a lower part of the trench isolation layer and a second buried layer for filling an upper part of the trench isolation layer. A semiconductor device preferably further includes a silicon oxide layer disposed between the semiconductor substrate and the silicon nitride liner. The silicon oxide layer includes a thermal oxide layer densified at a temperature over about 800° C.

    摘要: Fin-Field Effect Transistors (Fin-FETs) are provided. A fin is provided on an integrated circuit substrate. The fin defines a trench on the integrated circuit substrate. A first insulation layer is provided in the trench such that a surface of the first insulation layer is recessed beneath a surface of the fin exposing sidewalls of the fin. A protection layer is provided on the first insulation layer and a second insulation layer is provided on the protection layer in the trench such that protection layer is between the second insulation layer and the sidewalls of the fin.

    摘要: The present invention is directed toward a structure and method by which trench isolation for a wide trench and a narrow trench formed in first and second regions of a substrate may be achieved without formation of a void in an isolation layer, a groove exposing an isolation layer, or an electrical bridge between gates in a subsequent process. A lower isolation layer is formed on the substrate in a first and second trench. The lower isolation layer is patterned to fill a lower region of the first trench, and an upper isolation pattern is formed to fill the second trench and a remainder of the first trench. An aspect ratio of first trench is reduced, thereby preventing the occurrence of a void in the upper isolation layer, or a gap between the upper isolation layer and the substrate.
