Title: David Ian Pearson: Innovator in Sputtering Technology
Introduction
David Ian Pearson is a notable inventor based in Hampshire, GB. He has made significant contributions to the field of sputtering technology, holding a total of 2 patents. His work focuses on enhancing the efficiency and effectiveness of sputtering apparatuses.
Latest Patents
One of his latest patents is a vacuum sputtering apparatus. This innovative sputtering apparatus features a rotating magnet array designed to optimize the deposition process. The apparatus includes a rotatable array plate and a magnetic array composed of permanent magnets arranged around the plate's periphery. Each magnet is positioned perpendicular to the plate, with a pole of a first polarity facing toward the target. Additionally, a bar permanent magnet is affixed to the plate within the same quadrant of the group of magnets. This arrangement creates a closed-loop static magnetic field that is substantially triangular in shape, concentrated in the quadrant, and offset from the center axis of rotation. The design allows for a rotating magnetic field at the target, which patterns the plasma to achieve maximum plasma density in the shape of a kidney. This innovative approach results in an axi-symmetric target erosion profile, optimizing deposition uniformity at the substrate.
