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 of the post against a transferable component on a donor substrate with a first pressure sufficient to mechanically deform at least a portion of the relief features and to mechanically deform a region of the post between the relief features such that the relief features and the region between the relief features 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 such that the post contacts the component over a second contact area that is smaller than the first contact area; and
retracting the stamp from the receiving substrate such that the component is delaminated from the stamp, thereby printing 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.
