Latest Patents

Elke Eckstein holds a patent for an isotropic silicon etch process that is highly selective to tungsten. This back end of the line dry etch method involves etching a mask oxide and a temporary silicon mandrel after the formation of gate stacks and tungsten studs. The process utilizes a polymerizing oxide etch to selectively etch the mask oxide relative to tungsten and silicon. Additionally, it allows for the selective etching of silicon compared to silicon nitride, silicon oxide, and tungsten. The method effectively removes the silicon mandrel and associated silicon residual stringers by adjusting various parameters during the etching process. This innovative approach can utilize undoped polysilicon, doped polysilicon, or single crystal silicon.
