    Abstract: A method for fabricating a substrate includes forming a first substrate including a thin film transistor array, and inspecting a first surface of an inspecting device, wherein inspecting the first surface of the inspection device includes: generating first measurement data by detecting a first measurement light that is parallel to a surface of an inspection region in the first surface, generating second measurement data by detecting a second measurement light that is parallel to the surface of the inspection region, and inspecting a state of a surface of the inspection region by comparing the first measurement data with the second measurement data.

    Abstract: A wafer processing apparatus may include a reaction tube extending in a vertical direction and defining a process chamber for receiving a boat that holds a plurality of wafers. A gas injector may be configured to supply a reaction gas into the process chamber and may include a gas distributor extending in the vertical direction in the reaction tube. The gas injector may have a plurality of ejection holes for spraying the reaction gas. An inner diameter of the gas distributor may be at least 10 mm, and a sectional area ratio of the total sectional area of the ejection holes to a sectional area of the gas distributor is about 0.3 or less.
