Latest Patents

One of his significant patents is titled "Dual Si-Ge polysilicon gate with different Ge concentrations for CMOS device optimization." This patent describes a method for forming dual Si-Ge poly-gates with varying Ge concentrations. The process involves creating an NMOS active area and a PMOS active area on a semiconductor substrate, separated by an isolation region. A gate oxide layer is grown over the substrate in each active area, followed by the deposition of a polycrystalline silicon-germanium (Si-Ge) layer with a specific Ge concentration. The NMOS area is blocked while the PMOS area is exposed, allowing for Ge plasma doping and laser annealing to achieve a higher Ge concentration in the PMOS area. This innovative approach results in dual Si-Ge polysilicon gates that optimize the performance of integrated circuit devices.
