    摘要: Provided are a semiconductor laser diode and a method of manufacturing the same. The semiconductor laser diode includes a lower cladding layer disposed on a substrate; a ridge including an optical waveguide layer, an active layer, an upper cladding layer, and an ohmic contact layer, which are sequentially stacked on the lower cladding layer, and having a predetermined width, which is obtained by performing a channel etching process on both sides of the ridge; an oxide layer disposed on surfaces of the upper and lower cladding layer to control the width of the ridge; a dielectric layer disposed on left and right channels of the ridge; an upper electrode layer disposed on the entire surface of the resultant structure to enclose the ridge and the dielectric layer; and a lower electrode layer disposed on a bottom surface of the substrate. The method is simpler than a conventional process of manufacturing a semiconductor laser diode. Also, by controlling a wet oxidation time, the width of a ridge can be freely controlled and an ohmic contact layer can be automatically formed.

    摘要: Provided is a method of manufacturing a thin film transistor (TFT) including a transparent ZnO thin layer that is formed at a low temperature by causing a surface chemical reaction between precursors containing elements constituting the ZnO thin layer. The method includes the steps of: depositing a gate metal layer on a substrate and forming a gate electrode using photolithography and selective etching processes; depositing a gate insulator on the substrate having the gate electrode; forming source and drain electrodes; and depositing a ZnO thin layer on the gate insulator using a surface chemical reaction between precursors containing elements constituting the ZnO thin layer.
