摘要:
In a semiconductor device, the topmost wiring layer of the package board is formed from an insulation material in which the elongation at break is 20% or higher and Young's modulus is 1 GPa or less when the temperature is 10 to 30° C. This insulation material contains a reactive elastomer that reacts with epoxy resin or an epoxy resin curing agent; an epoxy resin; an epoxy resin curing agent; and a crosslinked styrene-butadiene rubber having a double bond and a hydroxyl group, a carboxylic group, or another polar group. It is therefore possible to provide a semiconductor device that has a wiring board in which the connection reliability in relation to temperature cycles is high and the adhesiveness between the insulation layer and the electroless copper plating layer is also high.
