Patent ID: 8889485

Claim:
A method for transferring active components from a source substrate to a destination substrate, the method comprising: providing a source substrate having a process side including active components therein or thereon, the active components having respective primary surfaces including electrical connections thereon adjacent the process side and respective secondary surfaces opposite the primary surfaces; pressing a first stamp having first pillars protruding therefrom against the active components on the process side of the source substrate to adhere the respective primary surfaces of the active components including the electrical connections thereon to respective transfer surfaces of the first pillars; pressing a second stamp having second pillars protruding therefrom against the active components on the first pillars of the first stamp to adhere the respective secondary surfaces of the active components to respective transfer surfaces of the second pillars, wherein the respective transfer surfaces of the second pillars have greater adhesive strength than those of the first pillars; and pressing the second stamp including the active components on the second pillars thereof against a destination substrate to adhere the respective primary surfaces of the active components including the electrical connections thereon to a receiving surface of the destination substrate.
