    摘要: The current disclosure is directed to methods and assemblies configured to deliver a mixture of germanium tetrafluoride (GeF4) and hydrogen (H2) gases to an ion implantation apparatus, so H2 is present in an amount in the range of 25%-67% (volume) N of the gas mixture, or the GeF4 and H2 are present in a volume ratio (GeF4:H2) in the range of 3:1 to 33:67. The use of the H2 gas in an amount in mixture or relative to the GeF4 gas prevents the volatilization of cathode material, thereby improving performance and lifetime of the ion implantation apparatus. Gas mixtures according to the disclosure also result in a significant Ge+ current gain and W+ peak reduction during an ion implantation procedure.

    摘要: A system and method for ion implantation is described, which includes a gas or gas mixture including at least one ionizable gas used to generate ionic species and an arc chamber that includes two or more different arc chamber materials. Using the system ionic species are generated in the arc chamber with liner combination, and one or more desired ionic species display a higher beam current among the ionic species generated, which is facilitated by use of the different materials. In turn improved implantation of the desired ionic species into a substrate can be achieved. Further, the system can minimize formation of metal deposits during system operation, thereby extending source life and promoting improved system performance.

    摘要: Regulator assemblies can be tested using test fluids selected to have a molecular weight about that of a selected fluid to be dispensed from a fluid storage and delivery vessel including the regulator assembly. The test fluid can be a single gas or a mixture. The test fluid can have a molecular weight of between 80% and 110% of the molecular weight of the selected fluid dispensed from the fluid storage and delivery vessel. Regulator assemblies tested in this manner can pass evaluation when they show fewer than two spikes on the initiation of flow of the test gas. These regulator assemblies can be installed into fluid storage and delivery vessels, particularly for storage and delivery of pressurized fluids.
