Latest Patents

Among his latest patents, one notable invention is a semiconductor device and method of fabricating the same. This method involves performing pre-halo ion implantation on a semiconductor substrate, followed by the formation of a first epitaxial layer over the substrate's upper surface. A second epitaxial layer is then formed over the first layer, culminating in the creation of a transistor at an active region of the second layer. The first epitaxial layer plays a vital role in preventing the diffusion of ions implanted during the pre-halo implantation process into the second epitaxial layer.

Another significant patent is a method of manufacturing a semiconductor device using a stress memorization technique. This process includes providing a substrate that supports a gate electrode, followed by amorphizing and doping the source/drain regions adjacent to the gate electrode. The method also involves forming a stress-inducing layer on the substrate to cover the amorphized regions and subsequently recrystallizing these regions through annealing. This innovative approach enhances the performance and reliability of semiconductor devices.
