Latest Patents

Yuejing Wang holds a patent for "Ion beam deposition of ruthenium thin films." This patent describes methods for forming a low resistivity ruthenium (Ru) thin film by depositing ruthenium onto a substrate via ion beam deposition. The process involves using an assist ion beam in a chamber containing reactive and noble gas species. The substrate temperature is maintained at a minimum of 250° C. The resulting thin ruthenium film has a thickness of no more than 30 nm and a resistivity of less than 12 μ·cm. The crystalline structure of the film comprises grains with a (0001) orientation, and the resistivity varies with thickness, achieving values as low as less than 9 μΩ-cm for films of 50 nm and thicker.
