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 20):
The method of preparing for a restart of an epitaxial reactor of  claim 19 , wherein the epitaxial wafer is manufactured as a dummy wafer, and a wafer corresponding to a Run in which actual MCLT measurement is performed is manufactured as an actual wafer.
