A method of making an optical device including forming a plurality of holes with varying radii milled vertically into a film, wherein said holes form a pattern. The radius of each hole determines an effective refractive index for said hole. The effective refractive index modifies a phase and an intensity of an incoming electromagnetic radiation as the radiation propagates through said hole. The device is configured to be operating equally for each linearly polarized radiation simultaneously, wherein the each linearly polarized radiation is normally incident on the device.

A method for forming nanoparticles includes forming a stack of alternating layers including a first material disposed between a second material. The stack of alternating layers is patterned to form pillars. A dielectric layer is conformally deposited over the pillars. The pillars are annealed in an oxygen environment to modify a shape of the first material of the alternating layers. The dielectric layer and the second material are etched selectively to the first material to form nanoparticles from the first material.

A process for producing a light emitting diode device, the process including: forming a plurality of quantum dots on a surface of a layer including a first area and a second area, the forming including: exposing the first area of the surface to light having a first wavelength while exposing the first area to a quantum dot forming environment that causes the quantum dots in the first area to form at a first growth rate while the quantum dots have a dimension less than a first threshold dimension; exposing the second area of the surface to light having a second wavelength while exposing the second area to the quantum dot forming environment that causes the quantum dots in the second area to form at a third growth rate while the quantum dots have a dimension less than a second threshold dimension; and processing the layer to form the LED device.

The disclosure relates to methods of printing indicia on a substrate using a tip array comprised of elastomeric, compressible polymers. The tip array can be prepared using conventional photolithographic methods and can be tailored to have any desired number and/or arrangement of tips. Numerous copies (e.g., greater than 15,000, or greater than 11 million) of a pattern can be made in a parallel fashion in as little as 40 minutes.

Devices and methods for forming a device are presented. The method includes providing a substrate prepared with at least a first region for accommodating an anti-fuse based memory cell. A fin structure is formed in the first region. The fin structure includes top and bottom fin portions and includes channel and non-channel regions defined along the length of the fin structure. An isolation layer is formed on the substrate. The isolation layer has a top isolation surface disposed below a top fin surface, leaving the top fin portion exposed. At least a portion of the exposed top fin portion in the channel region is processed to form a sharpened tip profile at top of the fin. A gate having a gate dielectric and a metal gate electrode is formed over the substrate. The gate wraps around the channel region of the fin structure.

Nanopillar-based closed ring resonator (CRR) MMs, utilizing displacement current in the nano gap medium between nanopillars that significantly increases energy storage in the MMs, leading to an enhanced Q-factor of at least 11000. A metallic nanopillar array is designed in the form of a closed ring (e.g., square-shape) CRR.
