What is Corrosion Fatigue? Corrosion fatigue is the combined action of fatigue and corrosion. It can produce a failure in fewer cycles and lower loads than if either corrosion or fatigue were acting alone. Of all corrosion failure mechanisms, it is the most difficult to identify especially in the presence of low-frequency loading. At very […]

As a silicon wafer manufacturer, you are faced with pressure to increase yield and speed up the manufacturing process—all while maintaining your product’s quality. Altering even minor processing parameters can generate stress on a wafer’s crystal lattice leading to an increased number of damaged or defective devices on a given wafer. Because most strain patterns […]
