WebSemiconductor wafer measurement requires a high degree of precision. The right metrology equipment and inspection processes are important, but so is procedural consistency and attention to detail. ... The result is two very different shape measurements. A positive bow become negative and the warp measurement may vary given that the wafer stress ... WebPresently, the only SEMI Standard for Bow is MF534-0707. Although reapproved relatively recently this method dates back almost 50 years, is not practical for high-volume manufacturing and in any case is not in significant use today. Through an apparent oversight, Bow was not included in MF1390. Bow is the deviation of the center point of the median surface of a free, un-clamped wafer from the reference plane, where the reference plane is defined by three corners of an equilateral triangle . This definition is based on now obsolete ASTM F534. Warp is the difference between the maximum and the … See more Bow and warp of semiconductor wafers and substrates are measures of the flatness of wafers.
