ABSTRACT:
In accordance with the present invention, there is provided a novel composition for attaching a semiconductor device to a substrate. The invention composition comprises liquid polycyanate ester monomer, electrically conductive filler rendered substantially free of catalytically active metal ions and a curing catalyst. Treatment of filler to render it free of catalytically active metal ions significantly extends the pot life of the composition.
