Latest Patents

Francois D Martinet holds a patent for a gas mixture and method for anisotropic selective etch of nitride. This patent describes a gas mixture for use in the selective dry etching of a nitride insulator layer relative to an oxide insulator layer. The gas mixture contains chlorine and oxygen, with the oxygen comprising 15% or less by volume. In a preferred process embodiment for etching Si₃N₄ and leaving a layer of SiO₂ therebelow, Cl₂ gas may be used in combination with 12% or less oxygen by volume. The etch selectivity of greater than five to one is achieved with this gas mixture when a plasma RF frequency of less than 1 MHz is utilized. Additionally, when a high-frequency RF component in the range of 10-27 MHz is added to the RF excitation signal, an etch uniformity of better than 3% is achieved.
