Latest Patents
Ho-Sen Chang holds a patent for a "Method for manufacturing a metal-insulator-metal capacitor." This method involves forming a metal wire, including copper, on a substrate to create a MIM capacitor. The process includes the formation of a dielectric film on the metal wire, followed by the creation of a top electrode film. The top electrode film is then etched to form the final electrode. A unique aspect of this invention is the removal of hard metallic polymer during the etching process using a mixture of oxygen gas and fluorocarbon-based gas. This innovation effectively prevents the lifting of thin films and increases the yield of the manufacturing process. Additionally, it ensures uniform capacitance by preventing damage to the dielectric film and oxidation of the bottom electrode. Ho-Sen Chang has 1 patent to his name.
