<p>A method of making varistor chips is disclosed. A workpiece of varistor material is sliced into slices of varistor material. The slices are in turn diced to make the varistor chips. The chips are etched in an etchant such as dilute citric acid to remove from their surfaces varistor material damaged during the slicing and/or dicing operations. Otherwise, the damaged varistor material adversely affects the leakage current characteristics of the varistor chips.</p> |
