摘要:
PROBLEM TO BE SOLVED: To improve the mounting reliability by reducing occurrence of void in terms of the flip chip mounting substrate and the flip chip mounting method which are related with a flip chip mounting of a semiconductor device using a bump. SOLUTION: A flip chip mounting substrate has a solder resist 30 and a center pad 28 which is flip chip-bonded with a center bump 3 attached to a semiconductor chip 1 on a substrate body 26. An underfill resin 35 is attached after the semiconductor chip 1 is mounted. The flip chip mounting substrate is structured in such a method that a center opening area 32 is formed which exposes the solder resist 30 to the center pad 28, and an edge area forming the center opening area 32 of the solder resist 30 overlaps partly with the outer periphery of the center pad 28.
