Abstract:
An apparatus for fabricating a semiconductor device includes a chamber, a processing part inside the chamber, a gas injection pipe connected to the chamber, a gas pumping pipe connected to the chamber, and a baffle assembly embedded in a chamber wall, and the baffle assembly includes a baffle plate having baffle holes, and a baffle guide surrounding an outer surface of the baffle plate.
Abstract:
In a method of inspecting a surface of a substrate, a first surface image of the substrate before loaded into a process chamber may be obtained. The first surface image may be processed to detect a defect on the surface of the substrate. Thus, the surfaces of all of the substrate may be inspected during a process may be performed without transferring the substrates.
