To satisfy customer demand for ultra-clean environments for wafer sort, CORWIL Technology (CORWIL) has added a Portable Clean Environment for wafer sort that is good to Class 1000. CORWIL’s one-stop solution from wafer sort, die prep, assembly, Package Test and Reliability provides the ability to understand how different pieces of the backend process affect each other in terms of yield.
Joe Foerstel, VP of Test for CORWIL said, “Customers have found that wafer sort in a very clean environment improves yield, especially when using certain RF probe technologies or probing devices with sensitive surface structures; particularly for our customers in the communications and medical industries.” “We have seen dramatic improvement of yields at Second Optical when customer’s wafers arrive from a cleaner environment, especially when back grind is one of the steps in the process,” added Jonny Corrao, CORWIL’s Director of Die Prep.
