Claim 15:
16. A thin film manufacturing apparatus comprising:
a chamber having an inner process space of a substrate and comprising an injection hole for injecting radicals to the process space and an exhaust hole for discharging the radicals;
a substrate support unit connected to the chamber to support the substrate in the chamber;
a heat source unit connected to the chamber and disposed opposite to the substrate support unit; and
a plasma generation unit connected to the injection hole of the chamber to supply the radicals between the substrate support unit and the heat source unit; and
a baffle connected to the chamber and comprising a movement passage of the radicals therein and a plurality of first exhaust holes communicating with the movement passage, which are formed in a top surface thereof,
wherein the process space is formed to have a height less than each of a width and a thickness thereof,
wherein the injection hole is formed at one side of the chamber in the thickness direction,
wherein the baffle is disposed at the other side of the chamber in the thickness direction to extend in the width direction,
wherein the exhaust holes are plural and formed at the other side of the chamber in the thickness direction to be provided at both sides of the baffle in the width direction, respectively,
wherein the plurality of first exhaust holes are spaced apart from each other,
wherein a portion of the plurality of first exhaust holes are formed at different heights in the height direction, and
wherein exhaust lines are connected to the plurality of exhaust holes, respectively, and a valve is installed on each of the exhaust lines.
