Abstract: Provided is a positive electrode active material including a plurality of crystallites A, wherein the plurality of crystallites A has a crystallite long-axis orientation degree DoA represented by Equation 1 below is 0.5 to 1, and a crystallite c-axis orientation degree represented by a cross product value of a c-axis rotation vector Rc of a crystal lattice of a crystallite obtained by electron backscatter diffraction (EBSD) analysis and a position unit vector P? of the crystallite is 0.5 to 1. A proportion of the plurality of crystallites A is 25% to 80% with respect to a total number of crystallites in a cross-section of a positive electrode active material. Further provided is a positive electrode and a lithium secondary battery including the positive electrode active material.

Abstract: A substrate processing apparatus may be utilized, for example, for a horizontally fixed organic material deposition equipment for manufacturing large-area displays. A substrate processing apparatus may include a titanium cooling plate having an upper surface and a lower surface; an electrostatic chuck including a first dielectric layer provided on the lower surface, an electrode layer provided on the first dielectric layer, and a second dielectric layer provided on the first dielectric layer and the electrode layer, and chucking a glass substrate using an electrostatic force; and a yoke plate positioned on the upper surface and chucking a mask using a magnetic force. The titanium cooling plate may further includes a first channel provided from the upper surface, a second channel provided from the first channel, and a titanium cover plate coupled to the first channel. The titanium cooling plate may provide a cooling flow path using the second channel.
