1,161,309. Semi-conductor devices. TELEDYNE Inc. 24 July, 1968 [3 Aug., 1967], No. 35278/68. Heading H1K. A resistor for an integrated circuit comprises a region 25 of semi-conductor material, whose resistivity determines the final resistance value of the resistor, inset in a further region 24 of semi-conductor material of higher resistivity in a moat 22 in a semi-conductor substrate 21, the further semi-conductor region 24 being isolated from the substrate 21 by a layer 23 of insulating material. The semi-conductor material is silicon, the further region being polycrystalline, and the isolating layer 23 is silicon dioxide. Ohmic contacts 27 are applied to the inset region 25 and the surface of the device is covered with a passivating layer 26. |
