Latest Patents

Kadar holds a patent for "Preferential Dielectric Gapfill." This patent focuses on methods for preferentially filling narrow trenches with silicon oxide while avoiding complete filling of wider trenches and open areas. The innovative approach involves depositing dielectric layers by introducing a silicon-containing precursor and ozone into a processing chamber. This results in a dense first portion of a silicon oxide layer, followed by a more porous second portion. The method ensures that narrow trenches are filled with dense material, while wider trenches can be effectively managed through wet etching.
