摘要： Embodiments of the invention relate to methods for depositing silicon-containing materials on a substrate. In one example, a method for selectively and epitaxially depositing a silicon-containing material is provided which includes positioning and heating a substrate containing a crystalline surface and a non-crystalline surface within a process chamber, exposing the substrate to a process gas containing neopentasilane, and depositing an epitaxial layer on the crystalline surface. In another example, a method for blanket depositing a silicon-containing material is provide which includes positioning and heating a substrate containing a crystalline surface and feature surfaces within a process chamber and exposing the substrate to a process gas containing neopentasilane and a carbon source to deposit a silicon carbide blanket layer across the crystalline surface and the feature surfaces. Generally, the silicon carbide blanket layer contains a silicon carbide epitaxial layer selectively deposited on the crystalline surface.

摘要： A method of preparing a clean substrate surface for blanket or selective epitaxial deposition of silicon-containing and/or germanium-containing films. In addition, a method of growing the silicon-containing and/or germanium-containing films, where both the substrate cleaning method and the film growth method are carried out at a temperature below 750° C., and typically at a temperature from about 700° C. to about 500° C. The cleaning method and the film growth method employ the use of radiation having a wavelength ranging from about 310 nm to about 120 nm in the processing volume in which the silicon-containing film is grown. Use of this radiation in combination with particular partial pressure ranges for the reactive cleaning or film-forming component species enable the substrate cleaning and epitaxial film growth at temperatures below those previously known in the industry.

摘要： Embodiments of the invention generally provide a method for depositing films or layers using a UV source during a photoexcitation process. The films are deposited on a substrate and usually contain a material, such as silicon (e.g., epitaxy, crystalline, microcrystalline, polysilicon, or amorphous), silicon oxide, silicon nitride, silicon oxynitride, or other silicon-containing materials. The photoexcitation process may expose the substrate and/or gases to an energy beam or flux prior to, during, or subsequent a deposition process. Therefore, the photoexcitation process may be used to pre-treat or post-treat the substrate or material, to deposit the silicon-containing material, and to enhance chamber cleaning processes. Attributes of the method that are enhanced by the UV photoexcitation process include removing native oxides prior to deposition, removing volatiles from deposited films, increasing surface energy of the deposited films, increasing the excitation energy of precursors, reducing deposition time, and reducing deposition temperature.

摘要： A method for synchronizing the rotation of a substrate boat with material deposition is disclosed. Whenever support rods of the substrate boat rotate past a deposition source, they will block deposition gas from reaching certain portions of the substrate. By stopping the deposition gas whenever the support rods are located between the substrate and the deposition source, a uniform deposition can be achieved.

摘要： Embodiments of the invention generally provide a method for depositing films using photoexcitation. The photoexcitation may be utilized for at least one of treating the substrate prior to deposition, treating substrate and/or gases during deposition, treating a deposited film, or for enhancing chamber cleaning. In one embodiment, a method for depositing silicon and nitrogen-containing film on a substrate includes heating a substrate disposed in a processing chamber, generating a beam of energy of between about 1 to about 10 eV, transferring the energy to a surface of the substrate; flowing a nitrogen-containing chemical into the processing chamber, flowing a silicon-containing chemical with silicon-nitrogen bonds into the processing chamber, and depositing a silicon and nitrogen-containing film on the substrate.

摘要： Improved methods of forming PZT thin films that are compatible with industry-standard chemical vapor deposition production techniques are described. These methods enable PZT thin films having thicknesses of 70 nm or less to be fabricated with high within-wafer uniformity, high throughput and at a relatively low deposition temperature. In one aspect, a source reagent solution comprising a mixture of a lead precursor, a titanium precursor and a zirconium precursor in a solvent medium is provided. The source reagent solution is vaporized to form a precursor vapor. The precursor vapor is introduced into a chemical vapor deposition chamber containing the substrate. In another aspect, before deposition, the substrate is preheated during a preheating period. After the preheating period, the substrate is disposed on a heated susceptor during a heating period, after which a PZT film is formed on the heated substrate.
