  • Publication number: 20230230815
    Abstract: A plasma processing apparatus includes a chamber providing a space for processing a substrate, a substrate stage configured to support the substrate within the chamber and including a lower electrode, an upper electrode facing the lower electrode, a focus ring in or on an upper peripheral region of the substrate stage to surround the substrate, and a plasma adjustment assembly in at least one of a first position between the upper electrode and the lower electrode and a second position between the focus ring and the lower electrode, the plasma adjustment assembly including a photoreactive material layer and a plurality of light sources configured to irradiate light onto a local region of the photoreactive material layer. A capacitance of the local region is changed as the light is irradiated to the local region.

  • Patent number: 10855497
    Abstract: A semiconductor device including a signal generator and decoding and timing skew adjusting circuit is provided. The signal generator is configured to receive n multi-level signals having m signal levels and convert the n multi-level signals into n*(m?1) single level signals having two signal levels. The decoding and timing skew adjusting circuit is configured to receive the single level signals, perform a predefined operation on the single level signals to generate an output signal, and compensate for timing skew between the n multi-level signals, using the single level signals. The n and m are natural numbers, where n>=2 and m>=3.
