Latest Patents
Grantham's most significant patent is titled "Single-pass growth of multilayer patterned electronic and photonic devices using a scanning localized evaporation methodology (SLEM)." This invention describes an apparatus designed for the close proximity deposition of thin films with high feature definition, high deposition rates, and significantly improved material economy. The SLEM system utilizes an array of fixed thin film heating elements, each capable of being individually energized, which are mounted on a transport mechanism inside a vacuum chamber. The process involves depositing evaporable material on a heating element, which is then transported to a substrate site for re-evaporation through a mask with patterned openings. This innovative method allows for the replication of patterns over the entire surface of the substrate, enabling the creation of multi-layered structures with high in-plane spatial pattern resolution.
