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： Methods of patterning low-k dielectric films are described. For example, a method includes forming and patterning a mask layer above a low-k dielectric layer, the low-k dielectric layer disposed above a substrate. Exposed portions of the low-k dielectric layer are modified with a plasma process. The modified portions of the low-k dielectric layer are removed selective to the mask layer and unmodified portions of the low-k dielectric layer.

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 of patterning low-k dielectric films are described.

摘要： A system to form a dielectric layer on a substrate from a plasma of dielectric precursors is described. The system may include a deposition chamber, a substrate stage in the deposition chamber to hold the substrate, and a remote plasma generating system coupled to the deposition chamber, where the plasma generating system is used to generate a dielectric precursor having one or more reactive radicals. The system may also include a radiative heating system to heat the substrate that includes at least one light source, where at least some of the light emitted from the light source travels through the top side of the deposition chamber before reaching the substrate. The system may also include a precursor distribution system to introduce the reactive radical precursor and additional dielectric precursors to the deposition chamber. An in-situ plasma generating system may also be included to generate the plasma in the deposition chamber from the dielectric precursors supplied to the deposition chamber.
