A method is described for constructing germanium high‐voltage diodes, utilizing 15‐mil germanium spheres instead of the usual flat wafer. The spheres are produced within a few minutes in quantities of several hundred thousand or more by blowing molten high‐purity germanium from a graphite crucible. The spherical pellets can be annealed, ground, etched, and assembled into diodes by techniques easily adaptable to automatic mass production. The assembled diode uses a sphere‐plane contact rather than the conventional whisker contact. Peak back‐voltages in the range 50–100 volts are easily obtainable. Series‐assembled units for higher voltages are easily made.
