发明名称 FLEXURE SUBSTRATE FOR SUSPENSION, SUSPENSION, SUSPENSION WITH HEAD, AND HARD DISK DRIVE
摘要 <P>PROBLEM TO BE SOLVED: To provide a flexure substrate for a suspension in which transmission loss of an electric signal is small and a differential impedance is reduced, a suspension, a suspension with a head, and a hard disk drive. <P>SOLUTION: In the flexure substrate for a suspension having a wiring pair composed of first wiring and second wiring, an opening region is formed in a metal support substrate under an area where the wiring pair is formed, a first conductor film having conductivity higher than that of the metal support substrate is formed in the opening region so as to overlap at least a portion of the first wiring and the second wiring in a planar view through a base insulating layer, and furthermore, a second conductor film having conductivity higher than that of the metal support substrate is formed so as to overlap at least a portion of the first wiring and the second wiring in a planar view through an intermediate insulating layer. <P>COPYRIGHT: (C)2013,JPO&INPIT
