Abstract

Abstract A method for high temperature reaction process, including the steps of mounting a substrate on which a radiation-sensitive polymer film is formed on a lower heating plate in a reaction vessel, sealing the reaction vessel while positioning an upper heating plate to above the substrate, maintaining a temperature difference between temperatures of the lower heating plate and the upper heating plate within a predetermined range, and supplying a reactive compound into the reaction vessel.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 111 words
In a method for high temperature reaction process for the treatment of a polymer film on a substrate with a reactive compound, using a reaction vessel capable of being tightly sealed and equipped with an upper heating plate positioned above said substrate, and a lower heating plate positioned below said substrate, both heating plates being designed to heat said substrate, said method for high temperature reaction process being performed with a temperature difference between a temperature TU° C. of said upper heating plate and a temperature TL° C. of said lower heating plate being maintained so that TU° C. falls in the range of (TL-70) to (TL-30) °C. during the treatment.
Claim 2
Dependent Claim 111 words
