Abstract: Generally, this disclosure provides examples relating to tuning etch rates of dielectric material. In an embodiment, a dielectric material is conformally deposited in first and second trenches in a substrate. Merged lateral growth fronts of the first dielectric material in the first trench form a seam in the first trench. The dielectric material is treated. The treating causes a species to be on first and second upper surfaces of the dielectric material in the first and second trenches, respectively, to be in the seam, and to diffuse into the respective dielectric material in the first and second trenches. After the treating, the respective dielectric material is etched. A ratio of an etch rate of the dielectric material in the second trench to an etch rate of the dielectric material in the first trench is altered by presence of the species in the dielectric material during the etching.

Abstract: An embodiment method includes forming a nanowire extending upwards from a substrate, wherein the nanowire includes: a bottom semiconductor region; a middle semiconductor region over the bottom semiconductor region; and a top semiconductor region over the middle semiconductor region. The method also includes forming a dielectric layer around and extending over the nanowire and forming a chemical mechanical polish-stop (CMP-stop) layer within the dielectric layer using an implantation process. After forming the CMP-stop layer, the dielectric layer is planarized.

Abstract: A color display device includes a plurality of pixel display elements and a driving circuit. Each of the pixel display elements includes a plurality of sub-pixel display elements. Each of the sub-pixel display elements includes first and second supports, first and second electrodes attached to inner faces of the first and second supports, respectively, a solution disposed between the first and second electrodes, and particles dispersed in the solution. The particles of the sub-pixel display elements of a same one of the pixel display elements are electrically polarizable by voltage signals supplied by the driving circuit, the voltage signals having the same predetermined driving frequency.

Abstract: A vehicle brake warning device for use in a vehicle with a brake pedal includes a detector for producing different electrical signals in response to the magnitude of the inertia force experienced during braking, a control circuitry receiving signals from the detector and having a varying frequency output depending upon the received signal, and a warning device activated by the varying frequency output of the control circuitry. Whenever a pressing force is exerted on the brake pedal to reduce the speed of the vehicle, the detector experiences an inertia force whose magnitude depends upon the speed of the vehicle. The detector sends out an appropriate signal dependent upon the magnitude of the inertia force to the control circuitry. The control circuitry activates the warning device to send out a warning signal which varies depending upon the magnitude of the inertia force.
