Patent number: 8312626Abstract: To make the fracturing position controlled conveniently with high precision when the substrate end of the probe contact is fractured and cut off. By compressing the front face of the substrate end portion with the pushing member, brittle fracture is generated on the substrate along the carved groove, and the substrate end portion is cut off from the substrate. The fracturing position in the above-mentioned fracturing is controlled so as to be along the fracturing position whose extension puts thereon the stress concentrating ends of two fracturing control structures. Here, the fracturing control structure is located with high positional precision on the front face of the substrate through the alignment technique of photolithography. In this way, resilient armatures constituted of the tips projected from the fracturing position coming to be the end of the substrate 11a can be stably formed with high precision.Type: GrantFiled: September 2, 2008Date of Patent: November 20, 2012Assignee: Yamaichi Electronics Co., Ltd.Inventors: Takeyuki Suzuki, Ryo Ujike, Yoshinori Wakabayashi
