10626013 · 2020-04-21 · ·

A photo-patterned fluorocarbon monolayer directly grafted to Si surface atoms provides anti-wetting performance at controlled locations, wherein the Si surface oxide is etched and reacted with fluorocarbon chains with a terminal CC double bond, resulting in SiC surface. As the direct SiC linkages are chemically robust, and much more resistant to decomposition than SiOC bonds, the resulting surface does not suffer from the shortcomings of current MEMS dispensers.

SYSTEMS, DEVICES, AND METHODS FOR DIRECT-WRITE PRINTING OF ELONGATED NANOSTRUCTURES

The present disclosure is directed to tailoring the structure of freeform nanotube macrostructures through extrusion-based additive manufacturing for fabrication of planar and three-dimensional features and objects. Ink containing nanomaterials can be extruded into a fluid to precipitate into a fiber that can be used to form solid structures. The fluid can include a coagulant that promotes rapid solidification in the precipitation of fibers. The fluid can be disposed into a bath that is in fluid communication with the extruded ink. Systems and devices for executing such processes, are also provided.

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.

Disclosed herein is a method comprising disposing on a first substrate a two-dimensional exfoliatable material; patterning an exfoliatable material using a photoresist in a manner such that a portion of the photoresist remains in contact with the two-dimensional exfoliatable material after the patterning; disposing a polymer layer on the two-dimensional exfoliatable material to form a printing block; contacting a substrate with the printing block; and removing the polymer layer and the photoresist from the printing block to leave behind the patterned exfoliatable material on the substrate.

Selective step coverage for micro-fabricated structures

A shadow mask having two or more levels of openings enables selective step coverage of micro-fabricated structures within a micro-optical bench device. The shadow mask includes a first opening within a top surface of the shadow mask and a second opening within the bottom surface of the shadow mask. The second opening is aligned with the first opening and has a second width less than a first width of the first opening. An overlap between the first opening and the second opening forms a hole within the shadow mask through which selective coating of micro-fabricated structures within the micro-optical bench device may occur.

A method of manufacturing a nanobeam structure by printing, namely coaxial focused electrohydrodynamic jet printing. In this method, under the combined action of electric field, thermal field and flow field, a stable coaxial jet is formed and used to print linear bilayer encapsulated structure on a substrate with a prefabricated support structure. Within the coaxial jet, the nanoscale inner liquid consisting of functional material is encapsulated by the microscale outer liquid consisting of high viscous material, which has the capability to directly print functional nanobeam structures. This high viscous material eliminates the disturbance of external micro-environment, and plays a role of supporting the printed inner structure before complete solidification of the inner material. A nanobeam structure only consisting of inner function material is formed on the substrate when the outer high viscous encapsulated material is removed.

The present invention provides for depositing a desired pattern (31) of magnetic material (30) on a non-magnetic substrate (20). Control of the deposition pattern (31) is achieved by use of a magnetised template (10) shaped to correspond to the desired deposition pattern. In use, the template (10) is placed behind the substrate (20). Subsequently, the front surface of the substrate (20) is exposed to a solution containing the magnetic material (30) to be deposited. The magnetic material (30) is attracted to the magnetised template (10) and consequently is deposited in a pattern (31) covering areas corresponding to the shape of the template (10).

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.
