Patent number: 9030218Abstract: In a method for thermal stabilization of a probe card, a probe card is adjusted to a prescribed temperature in a short time by making a heat source directly contact the probe card and is accurately determined whether the probe card is thermally stable. A heat transfer substrate is mounted on a mounting table. The temperature of the heat transfer substrate is adjusted through the mounting table. The mounting table is raised, and a plurality of probes is brought into contact with the heat transfer substrate at a prescribed target load. The contact load between the heat transfer substrate and the probes, which changes according to the thermal changes in the probe card, is detected. The mounting table is controlled vertically through a vertical drive mechanism such that the contact load becomes the target load until the probe card is thermally stable.Type: GrantFiled: December 9, 2011Date of Patent: May 12, 2015Assignee: Tokyo Electron LimitedInventors: Kazunari Ishii, Tetsuji Watanabe, Shinya Koizumi, Koichi Matsuzaki
