    摘要: A semiconductor device for use in a memory cell includes an active matrix, a capacitor structure, formed on top of the active matrix, an intermediate dielectric (IMD) layer formed on the capacitor structure and a barrier layer formed on the IMD layer, wherein the barrier layer includes a TiO2 layer and an Al2O3 layer. Since the Al2O3 layer is obtained by oxidizing the Ti1-xAlxN layer, the Al2O3 layer has a structure very dense. Therefore, the barrier layer prevents a capacitor structure from hydrogen damages caused by the formation of another IMD layer or a passivation layer during the following processes.

    摘要: Embodiments of the invention provide an improved process for depositing tungsten-containing materials. In one embodiment, the method for forming a tungsten-containing material on a substrate includes forming an adhesion layer containing titanium nitride on a dielectric layer disposed on a substrate, forming a tungsten nitride intermediate layer on the adhesion layer, wherein the tungsten nitride intermediate layer contains tungsten nitride and carbon. The method further includes forming a tungsten barrier layer (e.g., tungsten or tungsten-carbon material) from the tungsten nitride intermediate layer by thermal decomposition during a thermal annealing process (e.g., temperature from about 700° C. to less than 1,000° C.). Subsequently, the method includes optionally forming a nucleation layer on the tungsten barrier layer, optionally exposing the tungsten barrier layer and/or the nucleation layer to a reducing agent during soak processes, and forming a tungsten bulk layer on or over the tungsten barrier layer and/or the nucleation layer.

    摘要: Embodiments of the invention provide processes for vapor depositing tungsten-containing materials, such as metallic tungsten and tungsten nitride. In one embodiment, a method for forming a tungsten-containing material is provided which includes positioning a substrate within a processing chamber containing a lid plate, heating the lid plate to a temperature within a range from about 120° C. to about 180° C., exposing the substrate to a reducing gas during a pre-nucleation soak process, and depositing a first tungsten nucleation layer on the substrate during a first atomic layer deposition process within the processing chamber. The method further provides depositing a tungsten nitride layer on the first tungsten nucleation layer during a vapor deposition process, depositing a second tungsten nucleation layer on the tungsten nitride layer during a second atomic layer deposition process within the processing chamber, and exposing the substrate to another reducing gas during a post-nucleation soak process.
