Abstract:
A semiconductor fabrication method, comprising:determining off-state currents associated with non-dense transistors on a first semiconductor device formed by a fabrication process;determining drive currents associated with the non-dense transistors on the first semiconductor device;determining off-state currents associated with dense transistors on the first semiconductor device;estimating drive currents associated with the dense transistors on the first semiconductor device using the determined off-state and drive currents of the non-dense transistors and the off-state currents of the dense transistors on the first semiconductor device;adjusting one or more parameters of the fabrication process based on the estimated drive currents of the dense transistors on the first semiconductor device in order to calibrate drive currents of dense transistors with drive currents of non-dense transistors on semiconductor devices formed using the fabrication process.
