    摘要: Embodiments of the present invention relate to an apparatus and method of plasma assisted deposition by generation of a plasma adjacent a processing region. One embodiment of the apparatus comprises a substrate processing chamber including a top shower plate, a power source coupled to the top shower plate, a bottom shower plate, and an insulator disposed between the top shower plate and the bottom shower plate. In one aspect, the power source is adapted to selectively provide power to the top shower plate to generate a plasma from the gases between the top shower plate and the bottom shower plate. In another embodiment, a power source is coupled to the top shower plate and the bottom shower plate to generate a plasma between the bottom shower plate and the substrate support. One embodiment of the method comprises performing in a single chamber one or more of the processes including, but not limited to, cyclical layer deposition, combined cyclical layer deposition and plasma-enhanced chemical vapor deposition; plasma-enhanced chemical vapor deposition; and/or chemical vapor deposition.

    摘要: A method to selectively deposit a barrier layer on a metal film formed on a substrate is disclosed. The barrier layer is selectively deposited on the metal film using a cyclical deposition process including a predetermined number of deposition cycles followed by a purge step. Each deposition cycle comprises alternately adsorbing a refractory metal-containing precursor and a reducing gas on the metal film formed on the substrate in a process chamber.

    摘要: A method of forming a material on a substrate is disclosed. In one embodiment, the method includes forming a tantalum nitride layer on a substrate disposed in a plasma process chamber by sequentially exposing the substrate to a tantalum precursor and a nitrogen precursor, followed by reducing a nitrogen concentration of the tantalum nitride layer by exposing the substrate to a plasma annealing process. A metal-containing layer is subsequently deposited on the tantalum nitride layer.

    摘要: In one embodiment, a method for depositing materials on a substrate is provided which includes forming a titanium nitride barrier layer on the substrate by sequentially exposing the substrate to a titanium precursor containing a titanium organic compound and a nitrogen plasma formed from a mixture of nitrogen gas and hydrogen gas. In another embodiment, the method includes exposing the substrate to the deposition gas containing the titanium organic compound to form a titanium-containing layer on the substrate, and exposing the titanium-containing layer disposed on the substrate to a nitrogen plasma formed from a mixture of nitrogen gas and hydrogen gas. The method further provides depositing a conductive material containing tungsten or copper over the substrate during a vapor deposition process. In some examples, the titanium organic compound may contain methylamido or ethylamido, such as tetrakis(dimethylamido)titanium, tetrakis(diethylamido)titanium, or derivatives thereof.

    摘要: In one embodiment, a method for forming a metal-containing material on a substrate is provided which includes forming a metal containing barrier layer on a substrate by a plasma-enhanced cyclical vapor deposition process, exposing the substrate to a soak process, and depositing a conductive material on the substrate by a second vapor deposition process. The substrate may be exposed to a silicon-containing compound (e.g., silane) during the soak process. In some examples, a metallic nitride layer may be deposited subsequent to the soak process and prior to the second vapor deposition process. In other examples, the metal containing barrier layer contains metallic titanium, the metallic nitride layer contains titanium nitride, and the conductive material contains tungsten or copper. The plasma-enhanced cyclical vapor deposition process may further include exposing the substrate to a nitrogen precursor, such as nitrogen, hydrogen, a nitrogen/hydrogen mixture, ammonia, hydrazine, or derivatives thereof.
