Abstract:
A stamp for micro-transfer printing includes a support having a support stiffness and a support coefficient of thermal expansion (CTE). A pedestal layer is formed on the support, the pedestal layer having a pedestal layer stiffness that is less than the support stiffness and a pedestal layer coefficient of thermal expansion (CTE) that is different from the support coefficient of thermal expansion (CTE). A stamp layer is formed on the pedestal layer, the stamp layer having a body and one or more protrusions extending from the body in a direction away from the pedestal layer. The stamp layer has a stamp layer stiffness that is less than the support stiffness and a stamp layer coefficient of thermal expansion that is different from the support coefficient of thermal expansion.
