Latest Patents

Nagahaka’s patent, “Method for Forming and Patterning Film,” describes a way to pattern metallic films on a silicon substrate. The method uses a first metallic film that contacts both an insulation film and a conductive portion, along with a second metallic film that acts as a stress-adjustment layer. By controlling stress at the interface, the process can make adhesion to the insulation film weaker than adhesion to the conductive portion. An adhesive sheet can then selectively remove the metallic film from the insulation film while leaving it on the conductive portion. The approach is intended to make film patterning stable, straightforward, and low-cost.
