  • Patent number: 11581165
    Abstract: The present technology includes improved gas distribution designs for forming uniform plasmas during semiconductor processing operations or for treating the interior of semiconductor processing chambers. While conventional gas distribution assemblies may receive a specific reactant or reactant ratio which is then distributed into the plasma region, the presently described technology allows for improved control of the reactant input distribution. The technology allows for separate flows of reactants to different regions of the plasma to offset any irregularities observed in process uniformity. A first precursor may be delivered to the center of the plasma above the center of the substrate/pedestal while a second precursor may be delivered to an outer portion of the plasma above an outer portion of the substrate/pedestal. In so doing, a substrate residing on the pedestal may experience a more uniform etch or deposition profile across the entire surface.

  • Patent number: 11486562
    Abstract: Systems for apparatuses formed of light emitting devices. Solutions for controlling the off-state appearance of lighting system designs is disclosed. Thermochromic materials are selected in accordance with a desired off-state of an LED device. The thermochromic materials are applied to a structure that is in a light path of light emitted by the LED device. In the off-state the LED device produces a desired off-state colored appearance. When the LED device is in the on-state, the thermochromic materials heat up and become more and more transparent. The light emitted from the device in its on-state does not suffer from color shifting due to the presence of the thermochromic materials. Furthermore, light emitted from the LED device in its on-state does not suffer from attenuation due to the presence of the thermochromic materials. Techniques to select and position thermochromic materials in or around LED apparatuses are presented.
