Title: The Innovative Contributions of Melvin K. Holcomb in Advanced Sputter Target Technologies

Introduction: Melvin K. Holcomb is a notable inventor based in Grove City, OH, whose contributions to the field of materials science are reflected in his three patents. His work primarily focuses on the design and manufacturing of non-planar sputter targets, which play a crucial role in physical vapor deposition processes.

Latest Patents: Holcomb's latest patents highlight his innovative approach to sputter target design. One of his patents describes a non-planar sputter target that features differing crystallographic orientations. This characteristic promotes uniform material deposition and density patterns on substrates, enhancing the efficiency of the sputtering process. The design involves a closed dome end with one crystallographic orientation, while the sidewalls possess a different orientation. This construction is realized through hydroforming techniques that minimize the need for thermal annealing. Holcomb's efforts culminate in the creation of quick and cost-effective sputter targets that can be produced with great repeatability.

Another of his significant inventions is a variable thickness plate for forming variable wall thickness physical vapor deposition targets. This innovative approach enhances the target material thickness at strategic locations, significantly improving the yield of usable wafers per target. The manufacturing method involves forming a flat, circular target blank whose thickness decreases as a function of its radius, eventually shaping it into a dome-shaped target member. This manufacturing technique, known as clock rolling, allows for optimized target material distribution.
