Wafer Inspection System


FREMONT, CA — Wafer inspec- tion is always a critical stage for quality assurance for wafer foundry, integrated device man- ufacturing (IDM), fabless, and outsourced semiconductor as- sembly and test (OSAT). Since semiconductor devices are con- tinuously getting smaller and more complex, the requirement for wafer inspection has become more stringent to accommodate these changes. However, defects on the


wafer may be overlooked and may pass through the final stages of fabrication and assem- bly if they are not eliminated or filtered out, which could be a costly mistake for the manufac- turers. Consequently, this will lead to increasing demand for quality wafer production. The all-new Wi8i G2 PRO


solution is enhanced with hard- ware and programming features to accommodate both bare wafers (pre-dicing process) and mounted wafers (post-dicing

tion eliminates the need for hardware conversion on the

having a high-mix-low-volume of bare and mounted wafers. Hence, the Wi8i G2 PRO is the ideal solution to deliver high overall equipment effectiveness (OEE) which guarantees excel- lent wafer quality without any machine stop time. Based on the current mar-


ket trend, there is a demand for wafer inspection equipment to cater to larger wafers due to the increasing number of chip-relat- ed productions. To address this, the Wi8i G2


PRO offers a significant en- hancement in catering to a new type of wafer carrier box, Front Opening Unified Pod (FOUP) which is particularly important to users with such production practice to accommodate 12 inches of bare wafer transfer- ring.
