摘要： A method of forming a silicon oxide layer on a substrate. The method includes providing a substrate and forming a first silicon oxide layer overlying at least a portion of the substrate, the first silicon oxide layer including residual water, hydroxyl groups, and carbon species. The method further includes exposing the first silicon oxide layer to a plurality of silicon-containing species to form a plurality of amorphous silicon components being partially intermixed with the first silicon oxide layer. Additionally, the method includes annealing the first silicon oxide layer partially intermixed with the plurality of amorphous silicon components in an oxidative environment to form a second silicon oxide layer on the substrate. At least a portion of amorphous silicon components are oxidized to become part of the second silicon oxide layer and unreacted residual hydroxyl groups and carbon species in the second silicon oxide layer are substantially removed.

摘要： Catalyzed atomic layer deposition from a reduced number of precursors is described. A deposition precursor contains silicon, oxygen and a catalytic ligand. A hydroxyl-terminated substrate is exposed to the deposition precursor to form a silicon bridge bond between two surface-bound oxygens. The surface-bound oxygens were part of two surface-bound hydroxyl groups and the adsorption of the deposition precursor liberates the hydrogens. The silicon atom is also chemically-bound to one or two additional oxygen atoms which were already chemically-bound to the silicon within a same deposition precursor molecule. At least one of the additional oxygen atoms is further chemically-bound to the catalytic ligand either directly or by way of a hydrocarbon chain. Further exposure of the substrate to moisture (H2O) results in displacement of the additional oxygen which are replaced by hydroxyl groups from the moisture. The surface is again hydroxyl-terminated and the process may be repeated. The catalytic nature of the reaction enables the deposition to occur at low substrate temperatures. The chemically-embedded nature of the catalyst increases the deposition per cycle thereby reducing the number of precursor exposures to grow a film of the same thickness.
摘要翻译：描述了从减少数量的前体催化的原子层沉积。沉积前体含有硅，氧和催化配体。将羟基封端的衬底暴露于沉积前体以在两个表面结合的氧之间形成硅桥键。表面结合的氧是两个表面结合的羟基的一部分，并且沉积前体的吸附释放出氢。硅原子也与一个或两个另外的氧原子化学键合，这些氧原子已经在相同的沉积前体分子内与硅化学结合。至少一个额外的氧原子进一步与催化配体直接或通过烃链进行化学键合。底物进一步暴露于水分（H2O）会导致另外的氧被水分置换成羟基。表面再次被羟基封端，并且可以重复该过程。反应的催化性能使沉积在低的底物温度下发生。催化剂的化学嵌入性质增加每个循环的沉积，从而减少前体曝光的数量以生长相同厚度的膜。

摘要： A method of etching silicon-and-carbon-containing material is described and includes a SiConi™ etch in combination with a flow of reactive oxygen.
