    摘要： A semiconductor device comprising a silicon-on-insulator (SOI) substrate including a base substrate, an insulator layer, and a silicon layer, and a trench capacitor including at least one trench formed in the silicon-on-insulator substrate and extending through the base substrate, the insulator layer and the silicon layer, wherein the at least one trench includes at least one layer of silicon dioxide formed therein. In a preferred embodiment, semiconductor material disposed in the at least one trench forms a first electrode of a semiconductor capacitor, and semiconductor material of the SOI substrate which lies adjacent to the at least one trench forms a second electrode of the capacitor.

    摘要： An insulating structure includes a first silicon nitride layer, a tantalum pentoxide layer formed above the first silicon nitride (SiNx) layer, and a second silicon nitride layer formed above the tantalum pentoxide (Ta2O5) layer. The SiNx cladding layers prevent diffusion of the tantalum during heating. A high dielectric constant is provided. The thermal stability of the insulating structure is improved. The insulating structure may be included in a capacitor or a shallow trench isolation structure. An exemplary capacitor is formed with a substrate, a lower electrode, the three-layer SixNy/Ta2O5/SixNy structure and an upper electrode. The lower electrode may include a TiN layer formed over an aluminum layer, or a TiN layer formed over a polysilicon layer, or a polysilicon layer having an oxide barrier layer formed on it. The upper electrode may be a TiN layer or a polysilicon layer. An exemplary shallow trench isolation structure includes the SixNy/Ta2O5/SixNy structure as a liner on the sides and bottom of a shallow trench in the surface of a substrate. The shallow trench is filled with an oxide, such as TEOS. A variety of methods may be used for fabricating devices that include the SixNy/Ta2O5/SixNy structure.

    摘要： Gate oxides having different thicknesses are grown on a semiconductor layer by the process which comprises forming a semiconductor layer on a substrate, growing an oxide layer on the semiconductor layer, exposing a selected area of the oxide layer, amorphizing the semiconductor layer underlying the exposed oxide layer, removing the oxide layer to expose the semiconductor layer having both amorphized and non-amorphized regions and growing gate oxide on the amorphized and non-amorphized regions of the semiconductor layer. Gate oxide grown on the amorphized regions will be thicker than gate oxide grown on the non-amorphized regions.The process of the invention obviates the need for special integrated circuit manufacturing design modifications and can be utilized to fabricate a wide variety of devices, in particular, MOS-type devices.
