    摘要: A chemical vapor deposition (CVD) process uses a precursor gas, such as with a siloxane or alkylsilane, and a carbon-dioxide-containing gas, such as CO2 with O2 or CO2 with CxH(2x+1)OH where 1≦x≦5, to deposit a dielectric layer with no photoresist “footing”, a low dielectric constant, and high degrees of adhesion and hardness. Because nitrogen is not used in the deposition process (the carbon-dioxide-containing gas replaces nitrogen-containing gases in conventional processes), amines do not build into the deposited layer, thereby preventing photoresist “footing”.

    摘要: Embodiments of the present invention pertain to methods of forming patterned features on a substrate having a reduced pitch in two dimensions as compared to what is possible using standard photolithography processing techniques using a single high-resolution photomask. A spacer layer is formed over a two-dimensional square grid of cores with a thickness chosen to leave a dimple at the center of four cores on the corners of a square. The spacer layer is etched back to reveal the substrate at the centers of the square. Removing the core material results in double the pattern density of the lithographically defined grid of cores. The regions of exposed substrate may be filled again with core material and the process repeated to quadruple the pattern density.

    摘要: A planarization process in which an organic film prevents oxide dishing during the chemical mechanical polishing step. In the planarization process an organic film having high CMP selectivity to silicon dioxide is spun over silicon dioxide. A patterned mask is then placed over the organic film and the exposed portions of the organic film are etched away. The remaining portions of the organic film prevent oxide dishing during chemical mechanical polishing because the high CMP selectivity of the organic film to silicon dioxide stops the etching before oxide dishing occurs. The organic film may then be oxygen ashed off the planarized surface if so desired.

    摘要: An embodiment of the present invention provides methods for forming a carbon-containing layer having a low dielectric constant and good gap-fill capabilities. A method includes depositing a carbon-containing layer on a substrate and transforming the carbon-containing layer to remove at least some of the carbon. The transforming step may include annealing the carbon-containing layer in a furnace containing a hydrogen atmosphere, for example. The carbon-containing layer may be a carbon-doped silicon oxide material, where the transforming step changes the carbon-doped silicon oxide. Additionally, the method may include subjecting the annealed layer to a hydrogen and/or low oxygen plasma treatment to further remove carbon from the layer. Additionally, a step of adding a capping layer to the annealed, plasma treated material is provided. Products made by the above methods are also included, such as a product including a low k carbon-containing layer where the low k carbon-containing layer has been transformed to remove some of the carbon from the layer. An additional product includes a transformed carbon-containing layer further subjected to a hydrogen plasma treatment to remove more carbon from the layer. Further, a capping layer deposited over the transformed and hydrogen plasma treated layer is provided.
