PRINTING TRANSFERABLE COMPONENTS USING MICROSTRUCTURED ELASTOMERIC SURFACES WITH PRESSURE MODULATED REVERSIBLE ADHESION
First Claim
1. A method of printing transferable components, the method comprising:
- pressing a stamp including an elastomeric post having three-dimensional relief features protruding from a surface thereof against a transferable component on a donor substrate with a first pressure sufficient to mechanically deform a region of the post between the relief features to contact the component over a first contact area;
retracting the stamp from the donor substrate such that the component is adhered to the stamp;
pressing the stamp including the component adhered thereto against a receiving substrate with a second pressure that is less than the first pressure to contact the component over a second contact area that is smaller than the first contact area; and
retracting the stamp from the receiving substrate to delaminate the component from the stamp and print the component onto the receiving substrate.

Abstract
In a method of printing a transferable component, a stamp including an elastomeric post having three-dimensional relief features protruding from a surface thereof is pressed against a component on a donor substrate with a first pressure that is sufficient to mechanically deform the relief features and a region of the post between the relief features to contact the component over a first contact area. The stamp is retracted from the donor substrate such that the component is adhered to the stamp. The stamp including the component adhered thereto is pressed against a receiving substrate with a second pressure that is less than the first pressure to contact the component over a second contact area that is smaller than the first contact area. The stamp is then retracted from the receiving substrate to delaminate the component from the stamp and print the component onto the receiving substrate. Related apparatus and stamps are also discussed.

16. An apparatus for printing transferable components, the apparatus comprising:
-
a stamp comprising at least one elastomeric post protruding therefrom, the post having a surface configured for contact with a respective transferable component and including three-dimensional relief features protruding therefrom; and a transfer printing tool head including the stamp mounted thereon; and a controller configured to operate the transfer printing tool head to press the stamp including the post protruding therefrom against the respective transferable component on a donor substrate with a first pressure sufficient to mechanically deform a region of the post between the relief features to contact the respective transferable component over a first contact area, retract the stamp from the donor substrate such that the respective transferable component is adhered to the stamp, press the stamp including the respective transferable component adhered thereto against a receiving substrate with a second pressure that is less than the first pressure to contact the component over a second contact area that is smaller than the first contact area, and retract the stamp from the receiving substrate to delaminate the respective transferable component from the stamp and print the respective transferable component onto the receiving substrate. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
