    Abstract: A method of manufacturing a semiconductor device. A pre first semiconductor pattern having a crystalline semiconductor material is formed on a base substrate. A pre first insulation layer is formed on the pre first semiconductor pattern. A first semiconductor pattern is formed by defining a channel region in the pre first semiconductor pattern. A pre protection layer is formed on the pre first insulation layer. A pre second semiconductor pattern including an oxide semiconductor material is formed on the pre protection layer. A pre second insulation layer is formed on the pre second semiconductor pattern. The pre second insulation layer is patterned using an etching gas such that at least a portion of the pre second semiconductor pattern is exposed. A second semiconductor pattern is formed by defining a channel region in the pre second semiconductor pattern. The pre protection layer has a material with a first etch selectivity that is different from a second etch selectivity of the second insulation layer with respect to the etching gas.
