  • Patent number: 10483282
    Abstract: Embodiments of the present disclosure generally relate to an improved method for forming a dielectric film stack used for inter-level dielectric (ILD) layers in a 3D NAND structure. In one embodiment, the method comprises providing a substrate having a gate stack deposited thereon, forming on exposed surfaces of the gate stack a first oxide layer using a first RF power and a first process gas comprising a TEOS gas and a first oxygen-containing gas, and forming over the first oxide layer a second oxide layer using a second RF power and a second process gas comprising a silane gas and a second oxygen-containing gas.
    Type: Grant
    Filed: February 4, 2019

  • Patent number: 6083569
    Abstract: A method and apparatus for neutralizing a wafer in a plasma reactor following a deposition process which charges the wafer and hinders removal of the wafer from the plasma reactor. The wafer is exposed to a plasma of a noble gas such as helium to energize the reaction zone. Then a sufficient amount of an inert electronegative gas such as oxygen to neutralize the wafer is introduced into the plasma reactor in the absence of RF power or other gases. The neutralized wafer is readily removed from the plasma chamber.
