  • Patent number: 11814727
    Abstract: An atomic layer deposition (ALD) method can include pulsing a first reactant vapor into a reactor assembly. The first reactant vapor is supplied to a first reactant gas line. An inactive gas is supplied to a first inactive gas line at a first flow rate. The first reactant vapor and the inactive gas are fed to the reactor assembly by way of a first feed line. The reactor assembly is purged by supplying the inactive gas to the first inactive gas line at a second flow rate higher than the first flow rate. A first portion of the inactive gas can be fed back along a diffusion barrier portion of the first reactant gas line to provide an inert gas valve (IGV) upstream of the first inactive gas line. A second portion of the inactive gas can be fed to the reactor assembly by way of the first feed line.

  • Publication number: 20230197796
    Abstract: Threshold voltage (Vt) tuning layers may be sensitive to etching by reactants used to deposit overlying gate material, such as metal nitride. Methods for depositing Vt tuning layers are provided. In some embodiments Vt tuning layers may comprise a Vt tuning material in a neutral matrix. In some embodiments, processes for reducing or eliminating the etching of Vt tuning layers by halide reactants are described. In some embodiments a Vt tuning layer, such as a metal oxide layer, is treated by a nitridation process following deposition and prior to subsequent deposition of a metal nitride capping layer. In some embodiments an etch-protective layer, such as a NbO layer, is deposited over a Vt tuning layer prior to deposition of an overlying metal nitride layer.

  • Publication number: 20230080843
    Abstract: An apparatus capable of controlling a liquid may provide a source vessel to contain the liquid and an inlet tube for flowing the liquid into the source vessel. The inlet tube may extend into the source vessel and may be arranged to direct the flowing liquid onto a sidewall of the source vessel.
