886,393. Coating with germanium. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 16, 1960 [June 30, 1959], No. 21142/60. Class 82(2). [Also in Group XXXVI] A semi-conductor device is made by epitaxially depositing germanium on a gallium arsenide substrate. The device may be produced in the apparatus shown, germanium source 6 and iodine 7 being heated to 550‹C. by coil 2a to form germanium iodide which decomposes on gallium arsenide substrate 5 (maintained at 420‹C. by coil 2b) to deposit germanium layer 9. Thus a diode may be produced by depositing P type germanium on N type gallium arsenide. |
