Abstract
A method of forming a gate oxide layer with improved ability to resist process damage increases the reliability and yield of a transistor device. First, a nitrogen-containing gate oxide layer is formed on an element area of a silicon substrate. Then, a polysilicon layer is deposited on the gate oxide layer. Next, a gate doping process and a fluorine ion implantation are performed on the polysilicon layer. Then, a high-temperature tempering procedure is performed to make the fluorine enter the gate oxide layer.
