Patterned atomic layer etching and deposition using miniature-column charged particle beam arrays
Methods and systems for direct atomic layer etching and deposition on or in a substrate using charged particle beams. Electrostatically-deflected charged particle beam columns can be targeted in direct dependence on the design layout database to perform atomic layer etch and atomic layer deposition, expressing pattern with selected 3D-structure. Reducing the number of process steps in patterned atomic layer etch and deposition reduces manufacturing cycle time and increases yield by lowering the probability of defect introduction. Local gas and photon injectors and detectors are local to corresponding columns, and support superior, highly-configurable process execution and control.

TRANSFER PRINTING USING SHAPE MEMORY POLYMERS
A method of transfer printing comprises globally heating an array of stamps, where each stamp comprises a shape memory polymer with a light absorbing agent dispersed therein, and pressing the array of stamps to a donor substrate comprising a plurality of inks. Each stamp is thereby compressed from an undeformed adhesion-off configuration to a deformed adhesion-on configuration. The array of stamps is then cooled to rigidize the shape memory polymer and bind the plurality of inks to the stamps in the deformed adhesion-on configuration. The plurality of inks remain bound to the stamps while the array of stamps is positioned in proximity with a receiving substrate. A selected stamp in the array is then locally heated using a concentrated light source. The selected stamp returns to the undeformed adhesion-off configuration, and the ink bound to the selected stamp is released and transfer printed onto the receiving substrate.
