Latest Patents

Xianyuan Zhao holds a patent for "Methods for forming metal gapfill with low resistivity." This patent details methods for reducing the resistivity of metal gapfill, which involves depositing a conformal layer within a feature's opening and across the substrate's field. This conformal layer has a thickness of approximately 10 microns or less. Following this, a non-conformal metal layer is deposited directly on the conformal layer and on the field, utilizing an anisotropic deposition process that ensures the second thickness of the non-conformal metal layer is around 30 microns or greater. The final step in this method entails depositing a metal gapfill material that completely fills the opening without leaving any voids, significantly improving the reliability of metal components in semiconductor devices.
