Liquid metal alloy ion sources for B, Sb, and Si

  • 1. Faculty of Engineering Science, Osaka University, Toyonaka, Osaka, Japan

Description

B, Sb, and Si ion sources using liquid metal alloys have been fabricated and basic characteristics such as current--voltage relations, angular current intensity, energy distribution, and mass spectra have been measured. Singly charged B ions which amount to 33% of the total ions and have an angular current intensity of approx.40 μA/sr at a total energy spread (FWHM) of approx.20 eV were obtained using B--Ni--Pt alloys. Singly charged Si and Sb ions with an angular current intensity of approx.11 μA/sr and approx.1.4 μA/sr at an energy spread of approx.20 eV were obtained by using Si--Au and Sb--Pb--Au alloys, respectively. These ion sources could be operated for more than 10 h without any changes in mass spectra
