发明名称 Wiring substrate, semiconductor device and package stack semiconductor device
摘要 A wiring substrate of the present invention includes a terminal section, provided on a first surface of an insulating substrate, for wire or flip-chip bondings; a land section, provided on the insulating substrate, for an external connection terminal; wiring patterns, respectively provided on the first surface and a second surface on the other side of the first surface, for making electrical connection between the terminal section and the land section; and a support pattern, provided on the second surface corresponding in position to the terminal section, for improving bondings. The wiring substrate can relieve connection failure in bondings.
