Publication number: 20240194446Abstract: Embodiments of the disclosure include an apparatus and a method for controlling plasma uniformity by controlling plasma density in the bulk plasma over the center region and circumferential edge region of the substrate. Plasma uniformity can be controlled by use of an RF tuning circuit coupled to one of a plurality of electrodes positioned relative to a substrate during plasma processing. By adjusting the electrical characteristics of at least one of the RF tuning circuits, the effect that the generated RF fundamental frequency and related RF harmonic frequencies have on the plasma processing results can be controlled. Beneficially, the use of one or more of the tuning circuits and methods of using the same may be used to provide individual tuning knobs for controlling reactive neutral species concentration, ion energy and angular distribution, ion directionality and directionality uniformity, and separately controlling ion flux and reactive neutral species uniformity across the surface of the substrate.Type: ApplicationFiled: December 9, 2022Publication date: June 13, 2024Inventors: Linying CUI, James ROGERS, Keith HERNANDEZ, William CHIN, Leonid DORF

Patent number: 6580988Abstract: A method is disclosed for controlling the rear wheel angle in a four-wheel steering vehicle such as a pickup truck. The front wheels are steered using the conventional operator handwheel linked to the front wheels. The rear wheels are actuated with a reversible electric motor and the rear wheel angle controlled using a computer with inputs of vehicle velocity, operator handwheel position and correlated front wheel angle, and handwheel turning rate. Control of rear wheel angle starts with a correlation of ratios of rear wheel angle to front wheel angle, R/F, vs. vehicle velocity suitable, determined under steady state front steering angle and velocity conditions, to maximize the contribution of the rear wheels while avoiding side-slip of the vehicle.Type: GrantFiled: November 6, 2001Date of Patent: June 17, 2003Assignee: General Motors CorporationInventors: William Chin-Woei Lin, Yuen-Kwok Chin, Weiwen Deng, Scott P.
