TL;DR: In this paper, a nitride light emitting diode (LED) was proposed, which can improve light-emitting efficiency by increasing light emitting surface area, reduce operating voltage by simultaneously emitting light from six cells at once.

TL;DR: The microstructure and crystallographic texture of copper electrodeposits in millimeter scale through silicon vias are characterized using electron backscatter diffraction as mentioned in this paper , and columnar grains of Cu capture the linear motion of the local growth front during filling with a strong <110> orientation.

TL;DR: In this article, a light emitting diode package and a manufacturing method are provided to reduce an operating voltage by simultaneously emitting light from six cells, where a plurality of LED cells are formed on a substrate two or more groups are composed of the LED cells.

TL;DR: In this paper , two electroplating methods are proposed based on the concentration of the additive in the plating solution and by modulating the current density to develop multilayer laminate structures with alternating layers exhibiting different recrystallization behaviors to enhance the mechanical properties of Cu foils.
