A semiconductor device and a method for forming the same are provided. The leadframe strip is tested by electrically isolating at least the leads from the periphery of the leadframe strip such that at least some of the leads extend uninterrupted beyond a final lead outline of the unit leadframes after electrical isolation from the periphery of the leadframe strip. Compositions of GEP peptides, including in combination with other inflammatory mediators, are provided. This promotes the treatment liquid for dissolving the adhesive to permeate the adhesive to which the treatment liquid is supplied.
