Abstract: Semiconductor devices (e.g., GAA device structures) and processing methods and cluster tools for forming GAA device structures are described. The cluster tools for forming GAA device structures comprise a first etch chamber, a second etch chamber, and a third etch chamber. Each of the first etch chamber and the second etch chamber independently comprises a single-wafer chamber or an immersion chamber. One or more of the first etch chamber or the second etch chamber may be a wet etch chamber. In some embodiments, at least one of the first etch chamber, the second etch chamber, and the third etch chamber is a dry etch chamber. The cluster tool described herein advantageously reduces the number of cleaning processes, the total time between cleaning and processing operations, variations in time between processing and variation in sidewall loss compared to conventional cluster tools.

The method comprises implanting an inert species into a bit line metal layer having a first grain size on a substrate to form an amorphized bit line metal layer having a second grain size smaller than the first grain size. A film stack is then deposited on the amorphized bit line metal layer. The film stack and amorphized bit line metal layer are etched to form a patterned film stack on the substrate. The patterned film stack on the substrate is thermally annealed.

Abstract: Interconnect structures on a substrate have low resistivity and high dopant interfaces. In some embodiments, the structures may have an opening with a sidewall from an upper surface to an underlying metallic layer of copper, a barrier layer of tantalum nitride formed on the sidewall of the opening, a liner layer of cobalt or ruthenium formed on the barrier layer and on the underlying metallic layer, a first copper layer with a dopant with a first dopant content formed on the liner layer and filling a lower portion of the opening to form a via-the first dopant content is approximately 0.5 percent to approximately 10 percent, and a second copper layer with the dopant with a second dopant content formed on the first copper layer and filling the at least one opening—the second dopant content is more than zero to approximately 0.5 percent of the dopant and is less than the first dopant content.

Abstract: An eye wear comprises an optical filter disposed in front of an eye. The optical filter has a transmittance function of wavelength comprising a transmittance peak having a peak transmittance and a transmittance bandwidth. A transmittance outside the transmittance peak is at a lower level transmittance, wherein a ratio of the lower level transmittance to the peak transmittance is less than unity. The transmittance peak is at a central wavelength of a laser that emits laser light forming one of a laser spot and a laser line. The transmittance bandwidth is larger than a bandwidth of the laser light emitted by the laser. The laser spot or the laser line formed by the laser light emitted by the laser is viewed through the eye wear.

Abstract: A 3D imaging system comprises a phase detection autofocus (PDAF) image sensor, a lens for imaging a cross-section of a 3D object on the PDAF image sensor and an actuator for driving the lens for focusing each cross-section of the 3D object on the PDAF image sensor. The actuator drives the lens until the PDAF image sensor identifies an image of a first cross-section of the 3D object in-focus and records the image of the first cross-section. The PDAF image sensor records images of subsequent cross-sections of the 3D object formed by the lens driven by the actuator on the PDAF image sensor. The recorded images of each cross-section of the 3D object are stacked to form a 3D image of the 3D object.
