A plurality of transistors formed in a single substrate each have a portion of the base region to which an ohmic contact is applied extending through the overlying collector region to the surface and the emitter regions of the transistors have a common ohmic contact. A pair of transistors are formed in a single substrate using a method described and claimed in Specification 1,071,294. As shown, Figs. 4 and 6, an N-type silicon substrate 1, doped with arsenic and boron in the ratio 3:1, has an N-type silicon layer 4 weakly doped with arsenic epitaxially deposited on one face. The boron in the substrate 1 diffuses into the part of the epitaxial layer first deposited to form a thin P-type layer 3.

Windows 11 are etched in the oxide layer and aluminium is deposited and alloyed to form P-type regions 12 extending through regions 4 into contact with regions 3. Further windows 13 are etched and gold doped with antimony or arsenic is deposited and alloyed to form ohmic connections to region 4. Aluminium conductors 15, 16, 17 and 18 are now formed on the surface of the oxide layers and the base of the substrate is alloyed to a gold-plated " Kovar " (Registered Trade Mark) strip 19 which acts as the common emitter connection of the two transistors as indicated in Fig. 7.
