WebSpalling is one of the simplest ELO techniques as it does not require a release layer. Instead, a tensile stressor layer (typically nickel) is deposited on top the wafer. After attaching a handle layer to the stressor layer, epitaxial layers can be peeled away as the stress induces a fracture that propagates as a subsurface crack across the wafer (Fig. 8) … WebMay 27, 2024 · Spalling occurs when macropits form, then grow is size and coalesce into larger cavities on the gear tooth surface.
