Title: Innovator Jeff C. Sellers: Pioneering Advances in Plasma Processing Technology
Introduction
Jeff C. Sellers, an accomplished inventor residing in Palmyra, NY, holds an impressive portfolio of 8 patents. His groundbreaking work primarily focuses on plasma processing technologies that enhance various industrial applications. Sellers’ innovations represent the cutting edge of research and development in his field, making significant contributions to the engineering and materials science communities.
Latest Patents
Among his latest patents, Jeff C. Sellers has introduced a method titled "Preferential Sputtering of Insulators from Conductive Targets." This innovative technique utilizes pulses of positive voltage superimposed onto a negative dc sputtering current. This process creates a reverse bias that effectively charges insulating deposits on the target to the reverse bias level. When the negative sputtering voltage is reapplied, these deposits are preferentially sputtered away. By employing low duty cycle reverse bias pulses with a pulse width ranging from 0.25 to 3 microseconds at a pulse range of 40 to 200 KHz, Sellers’ technique aims to reduce or eliminate sources for arcing, thus enhancing efficiency and safety in applications.
Another noteworthy patent is his development of an "Etch Process Employing Asymmetric Bipolar Pulsed DC." This process facilitates etching a workpiece within a plasma chamber in preparation for subsequent coating processes. It involves applying a significant negative high voltage to the workpiece, while pulses of a positive voltage are strategically applied, resulting in a train of asymmetric bipolar pulses. The waveform features a dominant negative-going portion, reaching voltages ranging from -300 to -4,000 volts, contrasted by positive-going pulses between +50 to +300 volts, typically with pulse widths of 0.25 to 3 microseconds. This innovative approach allows for effective plasma etching followed by a sputter coating process, significantly improving manufacturing capabilities.
