step. Techniques such as dry plasma etching, wet chemical etching, and chemical mechanical polishing are commonly used as a fol-low-up operation after grinding. The wafer thickness at this point is between 275 l m for 2-in. wafers and 775l m for the current high volume 300-mm diameter wafers. The use of ultrathin dice requires additional wafer
