Abstract Controlled spalling in (100)-oriented germanium using a nickel stressor layer shows promise for semiconductor device exfoliation and kerfless wafering. Demonstrated spall depths of 7–60 μm using DC sputtering to deposit the stressor layer are appropriate for the latter application but spall depths
