Abstract: A structure and method operable to create a reusable template for detachable thin semiconductor substrates is provided. The template has a shape such that the 3-D shape is substantially retained after each substrate release. Prior art reusable templates may have a tendency to change shape after each subsequent reuse; the present disclosure aims to address this and other deficiencies from the prior art, therefore increasing the reuse life of the template.
