Latest Patents

One of Guannan Yang's latest patents is titled "Nano metal paste, and preparation and application thereof." This patent describes a method for preparing a nano metal paste, which involves several steps. First, an organic metallic salt and an organic reducing agent are added into water or an organic solvent to obtain a first mixture. Next, the first mixture is reacted under heating to obtain a second mixture containing metal nanoparticles. Finally, the second mixture is concentrated to obtain a nano metal paste containing 20-95% by weight of the metal nanoparticles. This patent also provides a conductive paste and a conductive ink prepared by using the nano metal paste as filler.

Another significant patent is "Interconnect structure for semiconductor with ultra-fine pitch and forming method thereof." This application relates to semiconductor manufacturing, specifically focusing on an interconnect structure for semiconductors with an ultra-fine pitch. The forming method includes preparing copper nanoparticles using a vapor deposition device, where coupling parameters of the vapor deposition device are adjusted to control the initial particle size of the copper nanoparticles. The process continues with depositing the copper nanoparticles on a substrate, invertedly placing a chip with copper pillars as I/O ports on the substrate, and subjecting the chip and the substrate to hot-pressing sintering to enable bonding.
