Patent ID: 8110325

Claim:
A method of treating a substrate, the method comprising: a first treatment process for exposing an initial substrate on which a first resist film is formed, heating the exposed initial substrate, and developing the heated initial substrate, thereby forming a first resist pattern; and a second treatment process for forming a second resist film on the initial substrate on which the first resist pattern is formed, exposing the initial substrate on which the second resist film is formed, heating the exposed initial substrate, and developing the heated initial substrate, thereby forming a second resist pattern, wherein, after the second treatment process is performed on the initial substrate, a line width of the second resist pattern formed on the initial substrate is measured, a first treatment condition in the first treatment process is compensated based on a measured value of the line width of the second resist pattern, the first treatment process is performed on one of subsequent substrates in compliance with the compensated first treatment condition, a line width of the first resist pattern formed on the initial substrate is measured, a second treatment condition in the second treatment process is compensated based on a measured value of the line width of the first resist pattern, and the second treatment process is performed on the subsequent substrate in compliance with the compensated second treatment condition.
