Abstract: A semiconductor device and method of manufacture are provided. After a patterning of a middle layer, the middle layer is removed. In order to reduce or prevent damage to other underlying layers exposed by the patterning of the middle layer and intervening layers, an inhibitor is included within an etching process in order to inhibit the amount of material removed from the underlying layers.

Abstract: An electrode controls transmittance of a blocking layer over a photodiode of a pixel sensor (e.g., a photodiode of a small pixel detector) by changing oxidation of a metal material included in the blocking layer. By using the electrode to adjust transmittance of the blocking layer, pixel sensors for different uses and/or products may be produced using a single manufacturing process. As a result, power and processing resources are conserved that otherwise would have been expended in switching manufacturing processes. Additionally, production time is decreased (e.g., by eliminating downtime that would otherwise have been used to reconfigure fabrication machines.

Abstract: An electronic device has a narrow viewing angle state and a wide viewing angle state, and includes a panel and a light source providing a light passing through the panel. In the narrow viewing angle state, the light has a first relative light intensity and a second relative light intensity. The first relative light intensity is the strongest light intensity, the second relative light intensity is 50% of the strongest light intensity, the first relative light intensity corresponds to an angle of 0°, the second relative light intensity corresponds to a half-value angle, and the half-value angle is between ?15° and 15°. In the narrow angle state, a third relative light intensity at each angle between 20° and 60° or each angle between ?20° and ?60° is lower than 20% of the strongest light intensity.

Abstract: According to the present disclosure, a measuring method of liquid mixture purity includes steps as follows. A storage tank is provided, wherein the storage tank is configured for storing a liquid mixture including formic acid and water. A calculating unit is provided, wherein a plurality of formic acid purity values are saved in the calculating unit. A pressure-decreasing and heating step is performed by reducing a pressure of the storage tank and heating the storage tank. A measuring step is performed by measuring in the inner space of the storage tank to obtain a pressure value, and measuring the liquid mixture simultaneously to obtain a temperature value. A calculating step is performed by inputting the pressure value and the temperature value into the calculating unit, wherein the calculating unit outputs one of the formic acid purity values corresponding thereto.

Abstract: A method includes forming isolation regions extending into a semiconductor substrate. A semiconductor strip is between the isolation regions. The method further includes recessing the isolation regions so that a top portion of the semiconductor strip protrudes higher than top surfaces of the isolation regions to form a semiconductor fin, measuring a fin width of the semiconductor fin, generating an etch recipe based on the fin width, and performing a thinning process on the semiconductor fin using the etching recipe.

Abstract: A circuit board includes a substrate and a metallic layer. A first area and at least one second area are defined on a portion of the substrate, the second area is located outside the first area. The metallic layer includes first test lines disposed on the first area and second test lines disposed on the second area. A first test pad of each of the first test lines has a first width, and a second test pad of each of the second test lines has a second width. The second width is greater than the first width such that probes of an electrical testing tool can contact the first and second test pads on the circuit board correctly during electrical testing.

Abstract: A thermoduct comprises a metallic tube with multiple trenches, cupric powder and a metallic net, wherein the metallic net and the cupric powder are disposed inside the metallic tube and function as a capillary texture. The cupric powder is sintered to adhere to recesses of trenches, and the metallic net is sintered to adhere to the inner wall of the metallic tube. In the present invention, the metallic net can confine the cupric powder inside the gap between the metallic net and the inner wall of the metallic tube, which enables the cupric powder to be sintered to firmly adhere to the recesses of the trenches; thus, the thermoduct can simultaneously have capillarity, permeability and thermal conductivity, and the backflow of the liquid working fluid is speeded up.

Abstract: A molding tool has a mold cavity provided with a recess with a blowing needle guiding seat. Located in the blowing needle guiding seat is a tapered hole in which the blowing needle is movably received to carry out the blowing process. The blowing needle is caused to descend so as to seal off the blow hole before the hollow object takes shape in the mold cavity. The hollow object so formed is therefore devoid of a blow hole.
