Title:
CORRECTION METHOD FOR SURFACE PLASMA PHOTOLITHOGRAPHIC PATTERN
Document Type and Number:
WIPO Patent Application WO/2023/077253
Kind Code:
A1
Abstract:
Disclosed in the present invention is a correction method for a surface plasma photolithographic pattern, comprising: forming multiple test patterns on a test mask, each test pattern at least being represented by a first test parameter and a second test parameter related to the first test parameter; exposing a photoresist layer by using the test mask containing the test patterns to form multiple photoresist patterns, each photoresist pattern at least being represented by a first exposure parameter and a second exposure parameter related to the first exposure parameter; establishing a first data table on the basis of a correspondence between the first test parameters and second test parameters of the test patterns and the first exposure parameters and second exposure parameters of the photoresist patterns; processing the first data table according to the first exposure parameters to obtain a second data table; and correcting second test parameters of multiple design patterns on the basis of the second data table to obtain corrected design patterns, and using the corrected design patterns to manufacture a mask for exposure.
