    Abstract: 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.

    Abstract: An ion implantation system is described, including: an ion implanter comprising a housing defining an enclosed volume in which is positioned a gas box configured to hold one or more gas supply vessels, the gas box being in restricted gas flow communication with gas in the enclosed volume that is outside the gas box; a first ventilation assembly configured to flow ventilation gas through the housing and to exhaust the ventilation gas from the housing to an ambient environment of the ion implanter; a second ventilation assembly configured to exhaust gas from the gas box to a treatment apparatus that is adapted to at least partially remove contaminants from the gas box exhaust gas, or that is adapted to dilute the gas box exhaust gas, to produce a treated effluent gas, the second ventilation assembly comprising a variable flow control device for modulating flow rate of the gas box exhaust gas between a relatively lower gas box exhaust gas flow rate and a relatively higher gas box exhaust gas flow rate, and a motive fluid driver adapted to flow the gas box exhaust gas through the variable flow control device to the treatment apparatus; and a monitoring and control assembly configured to monitor operation of the ion implanter for occurrence of a gas hazard event, and thereupon to responsively prevent gas-dispensing operation of the one or more gas supply vessels, and to modulate the variable flow control device to the relatively higher gas box exhaust gas flow rate so that the motive fluid driver flows the gas box exhaust gas to the treatment apparatus at the relatively higher gas box exhaust gas flow rate. Preferably, in a gas hazard event, the shell exhaust discharge from the housing is also terminated, to facilitate exhausting all gas within the housing, outside as well as inside the gas box, to the treatment unit.

    Abstract: 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.
