Abstract:
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.
Abstract:
Embodiments of the present invention provide systems and methods for depositing materials on either side of a freestanding film using selectively thermally-assisted chemical vapor deposition (STA-CVD), and structures formed using same. A freestanding film, which is suspended over a cavity defined in a substrate, is exposed to a fluidic CVD precursor that reacts to form a solid material when exposed to heat. The freestanding film is then selectively heated in the presence of the precursor. The CVD precursor preferentially deposits on the surface(s) of the freestanding film.

Abstract:
A method for the production of a fibrous network- substrate component. The method comprises the steps of providing a network of fibrous material (1) on a preliminary substrate (2) by filtering high aspect ratio molecular structures (HARM-structures) from gas flow, placing the network of fibrous material (1) on the preliminary substrate (2) in proximity to a secondary substrate (3), applying a force to the network of fibrous material (1) to preferably attract the network of fibrous material (1) from the preliminary substrate (2) to the secondary substrate (3) in order to transfer the network of fibrous material (1) from the preliminary substrate (2) to the secondary substrate (3), and removing the preliminary substrate (2) from the network of fibrous material (1).
Abstract:
The invention relates to a method for producing a device (120) having a three-dimensional magnetic structure (132), comprising a step of applying magnetic particles (130) onto or into a carrier element (122), wherein a plurality of hollow spaces that are at least partially connected to one another are formed between the magnetic particles, and wherein the magnetic particles are brought into contact with one another at contact points. The method also comprises a step of joining the magnetic particle at the contact points by coating the assembly formed by magnetic particles and the carrier element, wherein the hollow spaces are penetrated at least partially by the layer generated by the coating. The device comprises a conductor loop assembly (124) on the carrier element or a further carrier element, such that in the event of a current flow through the conductor loop assembly (1), an inductivity of the conductor loop assembly is altered by the three-dimensional magnetic structure, or (2) a force acts on the three-dimensional magnetic structure or the conductor loop assembly via a magnetic field generated by the current flow, or (3) in the event of a change of position of the three-dimensional magnetic structure, a current flow is induced via the conductor loop assembly.
