Latest Patents
One of her latest patents involves the planarization of a material system in a semiconductor device using a non-selective in situ prepared slurry. This innovation addresses complex chemical mechanical polishing (CMP) processes that require the removal of various dielectric materials, potentially in the presence of polysilicon. The adaptability of the slurry material at the point of use, by selecting an appropriate pH value, helps avoid agglomeration of abrasive particles. This dynamic adaptation of removal conditions is particularly beneficial when exposing polysilicon material in gate electrode structures during replacement gate approaches.
Another notable patent by Katja Steffen focuses on forming semiconductor resistors in a semiconductor device that comprises metal gates. This invention increases the etch resistivity of the resistors, allowing for efficient removal of polysilicon material during a wet chemical etch process while preserving the semiconductor material in resistive structures. The incorporation of xenon into the semiconductor material significantly enhances its etch resistivity, providing a robust solution for semiconductor manufacturing.
