摘要:
An improved deposition chamber (2) includes a housing (4) defining a chamber (18) which houses a substrate support (14). A mixture of oxygen and SiF4 is delivered through a set of first nozzles (34) and silane is delivered through a set of second nozzles (34a) into the chamber around the periphery (40) of the substrate support. Silane (or a mixture of silane and SiF4) and oxygen are separately injected into the chamber generally centrally above the substrate from orifices (64, 76). The uniform dispersal of the gases coupled with the use of optimal flow rates for each gas results in uniformly low (under 3.4) dielectric constant across the film.
摘要:
The present invention provides a method of depositing an amorphous fluorocarbon film using a high bias power applied to the substrate on which the material is deposited. The invention contemplates flowing a carbon precursor at rate and at a power level so that equal same molar ratios of a carbon source is available to bind the fragmented fluorine in the film thereby improving film quality while also enabling improved gap fill performance. The invention further provides for improved adhesion of the amorphous fluorocarbon film to metal surfaces by first depositing a metal or TiN adhesion layer on the metal surfaces and then stuffing the surface of the deposited adhesion layer with nitrogen. Adhesion is further improved by coating the chamber walls with silicon nitride or silicon oxynitride.

摘要:
A capacitor structure comprising a bottom electrode, an insulator and a top electrode, and method for manufacturing the same. The bottom and top electrodes preferably include a metal portion and a conducting oxygen-containing metal portion. In one embodiment, a layer of ruthenium is deposited to form a portion of the bottom electrode. Prior to deposition of the insulator, the ruthenium is annealed in an oxygen-containing environment. The insulator is then deposited on the oxygen-containing ruthenium layer. Formation of the top electrode includes depositing a first metal on the insulator, annealing the first metal and then depositing a second metal. The first and second metals may be ruthenium.

摘要:
A film of fluorine-doped silicon glass (“FSG”) is exposed to a nitrogen-containing plasma to nitride a portion of the FSG film. In one embodiment, the FSG film is chemically-mechanically polished prior to nitriding. The nitriding process is believed to scavenge moisture and free fluorine from the FSG film. The plasma can heat the FSG film to about 400° C. for about one minute to incorporate about 0.4 atomic percent nitrogen to a depth of nearly a micron. Thus, the nitriding process can passivate the FSG film deeper than a via depth.

An improved deposition chamber (2) includes a housing (4) defining a chamber (18) which houses a substrate support (14). A mixture of oxygen and SiF.sub.4 is delivered through a set of first nozzles (34) and silane is delivered through a set of second nozzles (34a) into the chamber around the periphery (40) of the substrate support. Silane (or a mixture of silane and SiF.sub.4) and oxygen are separately injected into the chamber generally centrally above the substrate from orifices (64, 76). The uniform dispersal of the gases coupled with the use of optimal flow rates for each gas results in uniformly low (under 3.4) dielectric constant across the film.

Methods and systems for handling a substrate through processes including an integrated electroless deposition process includes processing a surface of the substrate in an electroless deposition module to deposit a layer over conductive features of the substrate using a deposition fluid. The surface of the substrate is then rinsed in the electroless deposition module with a rinsing fluid. The rinsing is controlled to prevent de-wetting of the surface so that a transfer film defined from the rinsing fluid remains coated over the surface of the substrate. The substrate is removed from the electroless deposition module while maintaining the transfer film over the surface of the substrate. The transfer film over the surface of the substrate prevents drying of the surface of the substrate so that the removing is wet. The substrate, once removed from the electroless deposition module, is moved into a post-deposition module while maintaining the transfer film over the surface of the substrate.
