Abstract

See full text

The invention is based on the discovery that modified calcium carbonates can be used as fillers for the preparation of non-abrasive adhesive formulations that are useful in microelectronic applications. The modified calcium carbonate fillers possess functional groups, which form strong bonds to the thermoset matrix. Invention compositions display excellent rheological properties, in addition to a low coefficient of thermal expansion.
