摘要:
Provided are an apparatus for preparing a cathode active material precursor for lithium secondary batteries including a cylindrical outer chamber, an inner cylinder that has the same central axis as the outer chamber and is mounted to rotatably move along the central axis, an electric motor to transfer power to rotate the inner cylinder, a reactant inlet disposed on the outer chamber, to add reactants to a space between the outer chamber and the inner cylinder, and an outlet disposed in the outer chamber, to obtain reaction products after reaction in the space between the outer chamber and the inner cylinder, and a method for preparing a cathode active material precursor for lithium secondary batteries using the apparatus.
摘要:
A semiconductor device includes a substrate with a NMOS region and a PMOS region, a device isolation layer on the substrate to define active fins, and gate patterns on the substrate to have a length direction crossing the active fins, wherein the device isolation layer includes diffusion brake regions between respective pairs of the active fins, the diffusion brake regions being disposed adjacent to each other in a width direction of the gate patterns, and wherein a width of the diffusion brake region in the NMOS region is different from a width of the diffusion brake region in the PMOS region.
