Title: Philip B. Ramsey: Innovator in Pyrolytic Graphite Technology
Introduction
Philip B. Ramsey is a notable inventor based in Livermore, CA (US). He has made significant contributions to the field of materials science, particularly in the development of advanced pyrolytic graphite technologies. With a total of 2 patents, his work has had a profound impact on various applications in the industry.
Latest Patents
Ramsey's latest patents include a process for the fabrication of aluminum metallized pyrolytic graphite. This innovative method enhances the fabrication of pyrolytic graphite sputtering targets, providing superior heat transfer ability, longer life, and maximum energy transmission. The process involves contouring and segmenting anisotropic pyrolytic graphite to match the erosion profile of the sputter target. The graphite is oriented to maximize contact with a thermally conductive metal backing, and the contact surface is metallized with an aluminum coating using high rate physical vapor deposition (HRPVD). Additionally, the thermally conductive metal backing is joined to the metallized graphite target through various low-temperature bonding methods, including liquid-metal casting, powder metallurgy compaction, eutectic brazing, and laser welding.
Another significant patent is the design of a magnetron sputtering source. This source is engineered for sputtering coating substrates and features a high thermal conductivity electrically insulating ceramic along with a magnetically attached sputter target. This design eliminates the need for vacuum sealing and allows for direct fluid cooling of the cathode assembly. The compact design improves operating characteristics, versatility, and reduces fabrication costs. It also allows for easy retrofitting to most sputtering apparatuses, facilitating safe and cost-effective target replacement, installation, and removal.
