Abstract:
1. A method of forming a vertical inorganic alignment layer, the method comprising: disposing a process substrate in a process chamber inside which a first target having a silicon-containing material and a second target having a carbon-containing material are disposed; injecting a nonvolatile gas into the process chamber; supplying a power voltage to the first and second targets to activate the nonvolatile gas in a plasma state, wherein the activated nonvolatile gas in the plasma state collides with the first and second targets such that silicon atoms and carbon atoms are discharged from the first and second targets, respectively, thereby forming the vertical inorganic alignment layer comprising a silicon carbide on the process substrate, and irradiating an ion beam onto a surface of the vertical inorganic alignment layer to adjust a pretilt angle of the vertical inorganic alignment layer.
