<p>A high purity aluminum foil, has a uniform surface distribution of lead, boron and/or indium. More than 99.9% purity aluminum foil contains 0.1-10 ppm total of lead (Pb), boron (B) and/or indium (In) with a distribution, in a 0.1 mu m deep surface zone, such that their ion analysis signal intensity has a dispersion ratio, (Imax - Imin)/Imean, of less than 5, preferably 2. An Independent claim is also included for manufacture of the above thin foil.</p> |
