摘要:
A chemical vapor deposition (CVD) method for depositing a thin film on a surface of a substrate is described. The CVD method comprises disposing a substrate on a substrate holder in a process chamber, and introducing a process gas to the process chamber, wherein the process gas comprises a chemical precursor. The process gas is exposed to a non-ionizing heat source separate from the substrate holder to cause decomposition of the chemical precursor. A thin film is deposited upon the substrate.

A method of performing a filament-assisted chemical vapor deposition process is described. The method includes providing a substrate holder in a process chamber of a chemical vapor deposition system, providing a non-ionizing heat source separate from the substrate holder in the process chamber, disposing a substrate on the substrate holder, introducing a film forming composition to the process chamber, thermally fragmenting the film forming composition using the non-ionizing heat source, and forming a thin film on the substrate in the process chamber. The non-ionizing heat source includes a gas heating device through and/or over which the film forming composition flows. The method further includes remotely producing a reactive composition, and introducing the reactive composition to the process chamber to interact with the substrate, wherein the reactive composition is introduced sequentially and/or simultaneously with the introducing the film forming composition.

A method of depositing a thin film on a substrate in a deposition system is described. The method includes disposing a gas heating device comprising a plurality of heating element zones in a deposition system, and independently controlling a temperature of each of the plurality of heating element zones, wherein each of the plurality of heating element zones having one or more resistive heating elements. Additionally, the method includes providing a substrate on a substrate holder in the deposition system, wherein the substrate holder has one or more temperature control zones. The method further includes providing a film forming composition to the gas heating device coupled to the deposition system, pyrolyzing one or more constituents of the film forming composition using the gas heating device, and introducing the film forming composition to the substrate in the deposition system to deposit a thin film on the substrate.
摘要:
A gas heating device and a processing system for use therein are described for depositing a thin film on a substrate using a vapor deposition process. The gas heating device includes a heating element array having a plurality of heating element zones configured to receive a flow of a film forming composition across or through said plurality of heating element zones in order to cause pyrolysis of one or more constituents of the film forming composition when heated. Additionally, the processing system may include a substrate holder configured to support a substrate. The substrate holder may include a backside gas supply system configured to supply a heat transfer gas to a backside of said substrate, wherein the backside gas supply system is configured to independently supply the heat transfer gas to multiple zones at the backside of the substrate.
摘要:
A method for forming an air gap structure on a substrate is described. The method comprises depositing a sacrificial layer on a substrate, forming an adhesion-promoting layer between the sacrificial layer and the substrate, and depositing a capping layer over the sacrificial layer. The sacrificial layer and the capping layer are patterned and metalized. Thereafter, the sacrificial layer is decomposed and removed through the capping layer.
