In the manufacture of a junction transistor, a wafer 3 of semi. conductor is secured to a member 1, a portion lying over an aperture is then reduced to its final desired thickness, and electrodes 4 and 5 applied to opposite sides of the wafer. The member 1 may consist of metal, or of ceramic having a tin or other metallic layer 2 for securing the semi-conductor wafer. The wafer may consist of germanium, and the electrode material of indium. The whole may be mounted in a metal tube which assists cooling of the device. |
