Method and device for transferring components
A method for the transfer of components from a sender substrate to a receiver substrate includes provision and/or production of the components on the sender substrate, transfer of the components of the sender substrate to the transfer substrate, and transfer of the components from the transfer substrate to the receiver substrate. The components can be transferred selectively by means of bonding means and/or debonding means.
1 . A method for the transfer of components from a sender substrate to a receiver substrate, comprising:
providing and/or producing the components on the sender substrate;
first transferring the components from the sender substrate onto a transfer substrate, the first transferred components being electrostatically fixed to the transfer substrate; and
second transferring the components from the transfer substrate onto the receiver substrate,
wherein the components are transferred selectively by means of bonding means and/or debonding means.
2 . The method according to claim 1 , wherein one or more of the components are fixed, locally limited, during the first transferring and the second transferring by the bonding means.
3 . The method according to claim 2 , wherein the one or more of the fixed components are released, locally limited, during the first transferring and the second transferring by the debonding means.
4 . The method according to claim 1 , wherein, after the providing and/or the producing of the components, the components are tested for functionality.
5 . The method according to claim 1 , wherein the transfer substrate contacts and/or applies pressure to the components provided on the sender substrate during the first transferring so that the components are kept in a specific position between the sender substrate and the transfer substrate.
6 . The method according to claim 1 , wherein the components fixed to the transfer substrate contact and/or apply pressure to the receiver substrate during the second transferring so that the components are held between the transfer substrate and the receiver substrate.
7 . The method according to claim 1 , wherein a release layer and/or an adhesion layer is applied respectively on the sender substrate and/or the transfer substrate and/or the receiver substrate and/or the components, and
wherein the release layer and/or the adhesion layer, through action of the debonding means and/or the bonding means, change adhesive properties with respect to the components in an adhesive area.
8 . The method according to claim 1 , wherein the bonding means is a laser beam, and
wherein the sender substrate and/or the transfer substrate and/or the receiver substrate are permeable to laser radiation.
9 . The method according to claim 1 , wherein the transfer substrate comprises a plurality of fixing elements, one or more of the fixing elements being configured to electrostatically fix the first transferred components to the transfer substrate.
10 . The method according to claim 9 , wherein the fixing elements are made of a polymer material and/or have a design that corresponds with a design of a suction cup.
11 . The method according to claim 9 , wherein the transfer substrate is deformed during the first transferring by the fixing elements.
12 . The method according to claim 1 , wherein the transfer substrate is an elastic film.
13 . A device for the transfer of components using a method according to claim 1 .
14 . A light-emitting diode (LED) produced by a method according to claim 1 .
15 . The LED according to claim 14 , wherein the LED comprises a plurality of the components arranged upon one another and/or beside one another.
