His work focuses on methods and apparatuses for plasma generation and processing, which are crucial in various industrial applications.
Latest Patents
One of Gondai's latest patents is a plasma generating method. In this method, radio-frequency power is supplied to an electrode via a matching device from a radio-frequency power supply to generate plasma within a chamber. During the power supply, it is determined whether plasma is generated based on parameters reflecting plasma generation. If plasma is not generated, the frequency of the radio-frequency power is adjusted to set the load side reactance of the power supply to zero or close to zero.
Another notable patent is for a plasma processing apparatus and method. In this invention, after mounting a semiconductor wafer on an electrostatic chuck, the susceptor is switched from an electrically grounded state to a floated state. Subsequently, high-frequency power for plasma generation is applied, and a processing gas is excited into plasma. This process involves multiple timings for applying different voltages to achieve optimal plasma processing conditions.
