Introduction

Kenneth B. Fielder is a notable inventor based in Circleville, OH (US). 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 functionality of sputter target assemblies.

Latest Patents

Kenneth's latest patents include innovative designs for quick change sputter target assemblies. The first patent describes a sputtering target assembly featuring a sputtering gun with an inner and outer annular wall. This design incorporates a plurality of radially projecting set screws that are threadably movable within threaded apertures in the inner annular wall. A mounting ring is profiled to fit over the inner annular wall, with a recessed groove that secures the mounting ring using the set screws. Additionally, the target has a grooved inner annular surface for receiving spring ball plungers, ensuring that the target is securely retained to the sputtering gun.

The second patent presents a sputter source that relies on thermal expansion of an annular sputter target to maintain good physical contact with a peripheral cooling wall. This invention includes novel means for holding the sputter target in place when at ambient temperature. The preferred embodiment utilizes spring means that cooperate with a groove in either the inner or outer rim of the sputter target. By applying sufficient axial force, the gripping force of the spring means can be overcome, allowing for easy removal or insertion of the target. This design also includes a structure that can retrofit the quick change target into existing sputter sources.
