Abstract

A stamp for micro-transfer printing comprises a rigid support having a support coefficient of thermal expansion (support CTE). Pedestals are disposed on (e.g., directly on and in contact with) the rigid support. Each of the pedestals is spatially separated from any other of the pedestals. The pedestals have a pedestal coefficient of thermal expansion (pedestal CTE) and the pedestal CTE is greater than the support CTE. Posts are disposed on (e.g., directly on and in contact with) each of the pedestals. Each post has a post coefficient of thermal expansion (post CTE) that is greater than the support CTE.
