Abstract:
As a process of preparing for a restart of an epitaxial reactor in which epitaxial growth for a wafer is performed, an embodiment includes injecting a nitrogen gas into a process chamber provided in the epitaxial reactor and purging the gas for a predetermined time; heating the inside of the process chamber non-linearly according to time; and measuring MCLT for the epitaxial wafer after growing the epitaxial wafer. A method of preparing for a restart of an epitaxial reactor of the embodiment removes moisture and contaminants stagnated inside the process chamber at a higher rate compared to the related art and also reduces a time to reach the minimum value of MCLT for preparing for a restart of an epitaxial reactor, and thus a time for preparing for a restart of an epitaxial reactor may also be reduced.

Claim (Index 14):
The method of preparing for a restart of an epitaxial reactor of  claim 13 , wherein the step of equalizing the temperatures of upper and lower portions of the susceptor is performed by changing emissivity of an upper or lower portion dome of the process chamber.
