An improved silver-glass paste for bonding a silicon die to a ceramic substrate consisting essentially of silver flake, glass frit, resin, surfactant containing lyophilic and lyophobic groups and solvent. The surfactant provides a steric barrier around the silver and glass to stabilize the paste and reduce voiding and cracking when the paste is used to bond the die to the substrate.
