Abstract
A conductive paste may include a conductive component and an organic vehicle. The conductive component may include an amorphous metal. The amorphous metal may have a lower resistivity after a crystallization process than before the crystallization process, and at least one of a weight gain of about 4 mg/cm2 or less and a thickness increase of about 30 μm or less after being heated in a process furnace at a firing temperature.
