Abstract: Described are systems and methods of storing adsorbing diborane on carbon adsorption medium. The invention discloses a vessel for storing diborane. The vessel includes: a vessel interior; microporous carbon adsorbent in the vessel interior; diborane in the vessel interior at least partially adsorbed on the microporous adsorbent. The microporous adsorbent includes slit pores between graphite layers at a graphite layer spacing that increases an activation energy required for diborane degradation relative to an activation energy of degradation of non-adsorbed gaseous diborane at ambient pressure, and at the same temperature.

Abstract: Novel high purity dimethylaluminium chloride compositions are provided that are suitable for semiconductor applications, such as atomic layer etch and aluminum ion implantation. The reduction or minimization of specified gaseous impurities allows the vapor phase of the DMAC to have purity levels of 99.9 mol % or higher to selectively etch various atomic layers with high selectivity and high etch precision at acceptable etch rates and 99 mol % or higher to ion implant aluminum ions without substantial implantation of C2H3 ions into a wafer device, thereby avoiding degradation or failure of the wafer device. Storage conditions are established that are conducive to maintaining the high purity levels required for such semiconductor applications.

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) 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 au ion implantation procedure.

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.
