Abstract
A method of fabricating a MOSFET device in accordance with the present invention can protect the device from the short channel effect and decrease the resistance of a gate of the device. The fabricating method includes the following steps. A device including a substrate, an oxide layer, a gate and a lightly doped region is provided, wherein the oxide layer is formed on the substrate and the gate is formed on the oxide layer. A conducting layer is formed on the oxide layer, and the conducting layer is etched to form a first spacer. Then, the device is implanted to form a heavily doped region. A dielectric layer is deposited on the device, and the dielectric layer is etched to form a second spacer. The oxide layer is etched to expose part of the side walls of the gate. Then, a self-aligned silicide is further processed to complete the fabricating processes. As a result, the MOSFET device has an ultra-shallow junction under the first spacer to reduce the source/drain resistance and increase the operating rate of the device.
