Abstract
A method of producing a probe card where a sintering process is not required for each ejection of a droplet and fine bumps that become probes can be formed in a short time. A liquid material containing metal ultra-fine particles is ejected onto a substrate in accordance with a fine inkjet process, and fine bumps are formed on the substrate. The manufacturing process is simplified so that energy can be saved and resources can be saved.
