Abstract
Methods of forming local interconnects and high resistor polysilicon loads are disclosed. The local interconnects are formed by depositing a layer of polysilicon over CoSi.sub.2 in partially fabricated semiconductor wafers. The polysilicon is then coated with cobalt and annealed to form a second layer of of CoSi.sub.2. The method can be expanded to form a high resistor polysilicon load by depositing and patterning an oxide layer to form contact windows before application of the polysilicon layer. Another oxide layer is deposited over the polysilicon and patterned before application of the cobalt layer to define the areas which create the resistor load.
