Abstract: Provided is a substrate processing apparatus configured to process a substrate having a notch including a plurality of rollers contacting a circumference of the substrate and configured to rotate the substrate, a first sensor configured to sense an impact between the plurality of rollers and the substrate, and a signal processing unit configured to detect revolutions per unit time of the substrate, based on a first sensing signal output by the first sensor.

Abstract: The successful fabrication of alloy foam (or porous alloy) is very rare, despite their potentially better properties and wider applicability than pure metallic foams. The processing of three-dimensional copper-nickel alloy foams is achieved through a strategic solid-solution alloying method based on oxide powder reduction or sintering processes, or both. Solid-solution alloy foams with five different compositions are successfully created, resulting in open-pore structures with varied porosity. The corrosion resistance of the synthesized copper-nickel alloy foams is superior to those of the pure copper and nickel foams.

Abstract: A solid state drive (SSD) apparatus includes a case including an air tunnel disposed between an inner plate and an upper wall and an accommodation space between the inner plate and a lower wall. The air tunnel extends in a first direction, and both end parts of the air tunnel are exposed to the outside. A substrate is disposed in the accommodation space. At least one semiconductor chip is disposed on the substrate.

Abstract: A packaged integrated circuit device includes a substrate, and a conductive pad and a chip stack on the substrate. A primary conductive line electrically connects the pad on the substrate to a conductive pad on one of the chips in the chip stack. Secondary conductive lines electrically connect the pad on the one of the chips to respective conductive pads on ones of the chips above and below the one of the chips in the chip stack. The primary conductive line may be configured to transmit a signal from the pad on the substrate to the pad on the one of the chips in the chip stack, and the secondary conductive lines may be configured to transmit the signal from the one of the chips to the ones of the chips thereabove and therebelow at a same time.
