Abstract: Methods and related systems for filling a gap feature comprised in a substrate are disclosed. The methods comprise a step of providing a substrate comprising one or more gap features into a reaction chamber. The one or more gap features comprise an upper part comprising an upper surface and a lower part comprising a lower surface. The methods further comprise a step of subjecting the substrate to a first plasma treatment and subjecting the substrate to a second plasma treatment. Thus the upper surface is inhibited while leaving the lower surface substantially unaffected. Then, the methods comprise a step of selectively depositing a material on the lower surface.

Abstract: A method of fluid manipulation involves applying electric signals at one or more electrodes located on or adjacent to a surface in contact with a liquid that contains a surfactant. The electric field generated by the electric signals (e.g., biasing voltage) applied to the electrodes makes the liquid less wetting on the surface than the natural state and can be used to move or modify the shape of the liquid droplet placed on the surface. One embodiment makes a liquid dewet locally on a surface by applying electric signals locally on the surface so that the liquid can be electrically manipulated on a hydrophilic surface.

Abstract: Systems and methods for local augmented reality (AR) tracking of an AR object are disclosed. In one example embodiment a device captures a series of video image frames. A user input is received at the device associating a first portion of a first image of the video image frames with an AR sticker object and a target. A first target template is generated to track the target across frames of the video image frames. In some embodiments, global tracking based on a determination that the target is outside a boundary area is used. The global tracking comprises using a global tracking template for tracking movement in the video image frames captured following the determination that the target is outside the boundary area. When the global tracking determines that the target is within the boundary area, local tracking is resumed along with presentation of the AR sticker object on an output display of the device.
