Latest Patents

One of his latest patents is a method for the production of axially symmetric, graded and ungraded thickness thin film and multilayer coatings. This innovative maskless deposition technique avoids the use of apertures or masks to tailor the deposition profile. A motional averaging scheme allows for the deposition of uniform thickness coatings, independent of the substrate radius. The uniformity of the coating results from an exact cancellation of substrate radius-dependent terms, achieved when the substrate moves at a constant velocity. Additionally, if the substrate accelerates over the source, arbitrary coating profiles can be generated through appropriate selection and control of the substrate's center of mass equation of motion. The radial symmetry of the coating profile is produced by orbiting the substrate about its center of mass, while other distributions can be obtained by selecting a different rotation axis. This method establishes a direct mapping between the coating thickness and the substrate's equation of motion, enabling tailored coating profiles without the need for masks and apertures.

Another significant patent is for a giant magnetoresistive sensor. This sensor element features a three-dimensional micro-architecture that significantly improves sensitivity and allows for highly localized measurement of magnetic fields. The sensor is constructed from a multilayer film of alternately magnetic and nonmagnetic materials and is optimally operated in a current perpendicular to plane mode. This technology is particularly useful in magnetic read/write heads for high-density magnetic information storage and retrieval.
