Chip crack in wafer
WebStricter requirements in the wafer manufacturing process have made edge measurements important for both 200 mm and 300 mm wafers. In fact, the SEMI standard for 300 mm wafers specifically requires a “polished edge.” Polishing the edge is done in order to reduce wafer cracking and chipping under stress during transport or thermal processing. WebFast, can be programmed to probe entire chip Chip can be at wafer level or packaged (cover removed) Can measure through insulator by capacitive coupling Can be used for visual inspection - SEM mode Can measure Node voltages - mV range Voltage waveforms - subnanosecond time resolution
