Metal Contamination Testing on Production Wafers: MC100
Backside probing of in-line product wafers. Local mapping of metal concentration, carrier diffusion length and lifetime. Metal levels determined from -3x109 to -1x1014
atoms/cm3. Fully-automated testing for 200 mm and 300 mm wafers. Non-thermal metal-dopant dissociation procedure. 225 mapped data points per wafer. Options for corona deposition and oxide charge measurements (plasma damage
characterization).
