Latest Patents

One of her latest patents is titled "Formation of film superconductors by metallo-organic deposition." This patent describes a method for forming a superconducting Y.sub.1 Ba.sub.2 Cu.sub.4 O.sub.2 thin film using a metalorganic deposition technique. The process involves depositing a solution containing neodecanoates of Y, Ba, and Cu, along with a solvent that includes at least approximately 5 volume percent pyridine in xylene onto a substrate. The substrate is then pyrolyzed to thermally decompose the neodecanoates at around 500 degrees Celsius, followed by rapid thermal annealing.

Another notable patent is the "Method for forming patterned alumina film element." This invention outlines a technique for creating an alumina film on a specific area of a surface while preventing film formation on adjacent regions. An ink film made of aluminum carboxylate compound is applied to the surface and heated to partially decompose the compound. A positive photoresist layer is then applied and selectively irradiated to define a mask over the desired area. The unwanted photoresist material is removed using an aqueous alkaline solution, which also dissolves the underlying partially decomposed aluminum compound, except for the area protected by the mask. After stripping the mask, the aluminum compound is heated and further decomposed to yield the desired alumina film.
