  • Publication number: 20230125552
    Abstract: A micro-LED manufacturing device includes: a wafer stage on which a wafer is positioned; a substrate stage on which a substrate is positioned; a lower base formed below the substrate stage; a first driving member formed on the substrate stage so as to move the wafer stage; and a second driving member formed on the lower base so as to move the substrate stage. The micro-LED manufacturing device is formed such that the wafer stage moves over the substrate stage, and thus the substrate stage and the wafer stage can move synchronously with respect to the lower base.
