    • A method of forming a tungsten silicide gate in a semiconductor substrate is provided to overcome the distribution of F ion concentration by locally adjusting a dose of F using partial ion implantation. Distribution of a capacitance equivalent thickness of a gate oxide layer formed on a semiconductor wafer is obtained. A wafer is divided into at least two regions(11a,11b) according to the distribution of the capacitance equivalent thickness of the gate oxide layer. The divided regions of the wafer are implanted with impurity ion of different dose by using a wide ion beam(202) composed of plural wide ion beams(202a,202b) which are overlapped over each other in any region, thereby compensating for the distribution of the capacitance equivalent thickness of the gate oxide layer.
