The streams carry an electric current, and their electrified liquid slowly dissolves the germanium. When they have almost drilled through the slab, leaving only a few ten-thousandths of an inch, the current is quickly reversed. The drilling stops, and the reversed current deposits metallic indium on both sides of the thin germanium wafer. The result is a transistor with...
