    摘要: Methods of multiple patterning of low-k dielectric films are described. For example, a method includes forming and patterning a first mask layer above a low-k dielectric layer, the low-k dielectric layer disposed above a substrate. A second mask layer is formed and patterned above the first mask layer. A pattern of the second mask layer is transferred at least partially into the low-k dielectric layer by modifying first exposed portions of the low-k dielectric layer with a first plasma process and removing the modified portions of the low-k dielectric layer. Subsequently, a pattern of the first mask layer is transferred at least partially into the low-k dielectric layer by modifying second exposed portions of the low-k dielectric layer with a second plasma process and removing the modified portions of the low-k dielectric layer.

    摘要: Methods to reduce film cracking in a dielectric layer are described. The methods may include the steps of depositing a first dielectric film on a substrate and removing a top portion of the first dielectric film by performing an etch on the film. The methods may also include depositing a second dielectric film over the etched first film, and removing a top portion of the second dielectric film. In addition, the methods may include annealing the first and second dielectric films to form the dielectric layer, where the removal of the top portions from the first and the second dielectric films reduces a stress level in the dielectric layer.

    摘要: A method of depositing a silicon and nitrogen containing film on a substrate. The method includes introducing silicon-containing precursor to a deposition chamber that contains the substrate, wherein the silicon-containing precursor comprises at least two silicon atoms. The method further includes generating at least one radical nitrogen precursor with a remote plasma system located outside the deposition chamber. Moreover, the method includes introducing the radical nitrogen precursor to the deposition chamber, wherein the radical nitrogen and silicon-containing precursors react and deposit the silicon and nitrogen containing film on the substrate. Furthermore, the method includes annealing the silicon and nitrogen containing film in a steam environment to form a silicon oxide film, wherein the steam environment includes water and acidic vapor.
