A method of annealing a metal oxide on a temperature sensitive substrate formation includes the steps of providing a temperature sensitive substrate formation and forming a spacer layer on a surface of the substrate formation. A metal oxide semiconductor device is formed on the spacer layer, the device includes at least a layer of amorphous metal oxide semiconductor material, an interface of the amorphous metal oxide layer with a dielectric layer, and a gate metal layer adjacent the layer of amorphous metal oxide semiconductor material and the interface. The method then includes the step of at least partially annealing the layer of metal oxide semiconductor material by heating the adjacent gate metal layer with pulses of infra red radiation to improve the mobility and operating stability of the amorphous metal oxide semiconductor material while retaining at least the amorphous metal oxide semiconductor material adjacent the gate metal layer amorphous.
