Publication number: 20240113068Abstract: A method for forming an ultrafine-pitch all-copper interconnect structure is provided. Nano-copper particles are mixed with a solvent, a dispersant and a viscosity modifier to prepare a nano-copper paste. A chip with a preset number of copper pillars having a preset diameter and a substrate are selected, cleaned and pretreated. The chip is sucked and flipped by a bonding machine to make the copper pillars face outward. The chip is sucked through a suction nozzle of the bonding machine and dipped in the nano-copper paste. A protective gas is fed, and the copper pillars are aligned with copper pads on the substrate through an optical system of the bonding machine, bonded with the substrate at a preset pressure and temperature under ultrasonication, and cooled at room temperature to obtain the interconnect structure. An ultrafine-pitch all-copper interconnect structure fabricated by the method is also provided.Type: ApplicationFiled: November 2, 2023Publication date: April 4, 2024Inventors: Yu ZHANG, Ranyuan ZHANG, Junyu HE, Wenjun HUANG, Chengqiang CUI, Guannan YANG
