Patent ID: 8247890

Claim:
A wiring circuit structure to be connected to a semiconductor element having a bump provided on an electrode thereof, comprising: at least a structure having a conductor layer formed as a circuit pattern on a base insulating layer, and a terminal for connection to the bump of the semiconductor element formed on the conductor layer, wherein: a supporting column is formed in the vicinity of the terminal on the upper face of the base insulating layer, supposing the protrusion height of the bump from the semiconductor element to be connected is B, the height of the supporting column is H, the height of the terminal is h, and the layer thickness of the terminal is t, as measured from the upper face of the base insulating layer as the reference surface, the height H of the supporting column is determined to satisfy; B<H<h+B when a semiconductor element having a bump with the provision of t<B is to be connected, or h<H<h+B when a semiconductor element having a bump with the provision of t≧B is to be connected; whereby compression that causes the terminal to reach the electrode of the element is prevented by the presence of the supporting column when the wiring circuit structure is superposed on the semiconductor element to bring the terminal into contact with the bump of the element, and the two members are pressed and connected to each other.
