Title:
METHOD FOR ESTABLISHING TEMPERATURE DISTRIBUTION MAP LIBRARY AND METHOD FOR ACQUIRING WAFER SURFACE TEMPERATURE
Document Type and Number:
WIPO Patent Application WO/2024/001047
Kind Code:
A1
Abstract:
The embodiments of the present application disclose a method for establishing a temperature distribution map library and a method for acquiring a wafer surface temperature. The method for establishing a temperature distribution map library involves: performing a temperature test to obtain a surface temperature distribution situation of a wafer; performing wafer simulation analysis to determine candidate simulation parameters causing a simulation result to conform to the temperature test result; changing the boundary conditions of the temperature test and again performing a temperature test; inputting the candidate simulation parameters into the changed boundary conditions and again performing simulation analysis, so as to determine a set of conforming simulation parameters causing the simulation result to conform to the temperature test result; based on the conforming simulation parameters, obtaining surface temperature distribution situations for the wafer under different boundary conditions, so as to construct a temperature distribution map library. By means of the temperature distribution map library, the present application is not only able to more-precisely and rapidly determine a wafer surface temperature distribution situation, avoiding performing multiple temperature tests, but is additionally able to reduce the cost of acquiring a wafer surface temperature.
