Latest Patents

Ya-Yi Cheng holds a patent for a "Fin field-effect transistor device and methods of forming." This patent describes a method of forming a semiconductor device that includes several intricate steps. These steps involve forming a gate structure over a fin that protrudes above a substrate, creating a source/drain region adjacent to the gate structure, and forming an interlayer dielectric (ILD) layer over the source/drain region. The process also includes forming an opening in the ILD layer to expose the source/drain region, followed by the formation of a silicide region and a barrier layer. The barrier layer consists of silicon nitride, which undergoes a reduction in concentration in its surface portion. After this reduction, a seed layer is formed on the barrier layer, and an electrically conductive material is added to fill the opening.
