    Abstract: A method and structure for providing conformal doping of FinFET fin structures, for example by way of a thermal treatment process, includes forming a gate stack at least partially over a fin extending from a substrate. In various embodiments, a barrier metal layer is deposited over the gate stack. By way of example, a thermal fluorine treatment is performed, where the thermal fluorine treatment forms a fluorinated layer within the barrier metal layer, and where the fluorinated layer includes a plurality of fluorine atoms. In some embodiments, after forming the fluorinated layer, an anneal is performed to drive at least some of the plurality of fluorine atoms into the gate stack (e.g., into the interfacial layer and the high-K dielectric layer), thereby conformally doping the gate stack with the at least some of the plurality of fluorine atoms.

  • Patent number: 9927616
    Abstract: Transparent displays enable many useful applications, including heads-up displays for cars and aircraft as well as displays on eyeglasses and glass windows. Unfortunately, transparent displays made of organic light-emitting diodes are typically expensive and opaque. Heads-up displays often require fixed light sources and have limited viewing angles. And transparent displays that use frequency conversion are typically energy inefficient. Conversely, the present transparent displays operate by scattering visible light from resonant nanoparticles with narrowband scattering cross sections and small absorption cross sections. More specifically, projecting an image onto a transparent screen doped with nanoparticles that selectively scatter light at the image wavelength(s) yields an image on the screen visible to an observer. Because the nanoparticles scatter light at only certain wavelengths, the screen is practically transparent under ambient light.

  • Patent number: 9898257
    Abstract: An automatic probe construction system and the method thereof are provided. The automatic probe construction system includes a data dereference analysis module, a probe selection module, and a probe verification module. The data dereference analysis module dereferences a plurality of target data of an electronic apparatus according to a plurality of pointers, and constructs a plurality of candidate probes. The probe selection module constructs a control flow graph according to the candidate probes and an instruction code of an executable image file, to select via the control flow graph from the candidate probes at least one dedicated probe. The probe verification module searches the executable image file for an instruction code corresponding to the dedicated probe, to verify the dedicated probe. Therefore, the dedicated probe can be constructed automatically, and the number of the dedicated probes is thus limited.

  • Publication number: 20170299149
    Abstract: A transparent display includes nanoparticles having wavelength-selective scattering (e.g., resonant scattering) to preferentially scatter light at one or more discrete wavelengths so as to create images. The nanoparticles transmit light at other wavelengths to maintain a high transparency of the display. The nanoparticles are disposed in proximity to a thin film, which can enhance the scattering the process by reflecting light back to the nanoparticles for re-scattering or increasing the quality factor of the resonant scattering.

  • Patent number: 9716016
    Abstract: One or more techniques or systems for forming an electrostatic discharge (ESD) clamp are provided herein. In some embodiments, the ESD clamp includes a first pad and a second pad. For example, the first pad is a positive supply voltage (Vdd) pad and the second pad is a negative supply voltage (Vss) pad. In some embodiments, active regions and oxide regions are associated with substantially rounded shapes or obtuse angles. Additionally, metal regions are configured to be in contact with at least some of at least one of the active regions or the oxide regions and the first pad. In some embodiments, the metal regions are substantially wedge shaped. In this manner, an ESD clamp with enhanced performance is provided, at least because the respective active regions are substantially rounded or associated with obtuse angles, for example.

  • Patent number: 9458989
    Abstract: Disclosed herein are transparent color displays with nanoparticles made with nonlinear materials and/or designed to exhibit optical resonances. These nanoparticles are embedded in or hosted on a transparent substrate, such as a flexible piece of clear plastic or acrylic. Illuminating the nanoparticles with invisible light (e.g., infrared or ultraviolet light) causes them to emit visible light. For example, a rare-earth doped nanoparticle may emit visible light when illuminated simultaneoulsy with a first infrared beam at a first wavelength ?1 and a second infrared beam at a second wavelength ?2. And a frequency-doubling nanoparticle may emit visible light when illuminated with a single infrared beam at the nanoparticle's resonant frequency. Selectively addressing these nanoparticles with appropiately selected pump beams yields visible light emitted from the nanoparticles hosted by the transparent substrate in a desired pattern.
