  • Patent number: 12142469
    Abstract: Embodiments herein provide plasma processing chambers and methods configured for fine-tuning and control over a plasma sheath formed during the plasma-assisted processing of a semiconductor substrate. Embodiments include a sheath tuning scheme, including plasma processing chambers and methods, which can be used to tailor one or more characteristics of a plasma sheath formed between a bulk plasma and a substrate surface. Generally, the sheath tuning scheme provides differently configured pulsed voltage (PV) waveforms to a plurality of bias electrodes embedded beneath the surface of a substrate support in an arrangement where each of the electrodes can be used to differentially bias a surface region of a substrate positioned on the support. The sheath tuning scheme disclosed herein can thus be used to adjust and/or control the directionality, and energy and angular distributions of ions that bombard a substrate surface during a plasma-assisted etch process.

  • Patent number: 12075538
    Abstract: A load control device (e.g., an LED driver) for controlling the intensity of a lighting load (e.g., an LED light source) may provide a wide output range and flicker-free adjustment of the intensity of the lighting load. The load control device may comprise a load regulation circuit, a control circuit, and a filter circuit (e.g., a boxcar filter circuit) that operates in a different manner in dependence upon a target current. When the intensity of the lighting load is near a low-end intensity, the control circuit may adjust an operating frequency of the load regulation circuit in response to the target current, and may control the filter circuit to filter a current feedback signal during a filter window that repeats on periodic basis. When the intensity of the lighting load is near a high-end intensity, the control circuit may control the filter circuit to constantly filter the current feedback signal.
