Abstract:
A method of forming an electrically conductive line comprising:forming a refractory metal silicide on and in ohmic electrical connection with semiconductive material comprising polycrystalline silicon, the refractory metal silicide having a first crystalline phase; providing a layer of compressive stress inducing material operatively coupled with the refractory metal silicide, the layer of compressive stress inducing material being configured to permit a phase change of the first crystalline phase to a second crystalline phase at a temperature of less than or equal to 750Â° C.; after providing the layer of compressive stress inducing material, annealing the refractory metal silicide at a temperature of less than or equal to 750Â° C. to transform the first crystalline phase to the second crystalline phase, the second crystalline phase being more dense and more electrically conductive than the first crystalline phase; and patterning the semiconductive material and the refractory metal silicide into a conductive line.
