Title:
MANUFACTURE OF SCANNING ELECTRON MICROSCOPE SYSTEM AND INTEGRATED CIRCUIT
Document Type and Number:
Japanese Patent JP3720201
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method and system for analyzing a profile of wafer strength comprising a step where a wafer is scanned for generating a scan signal.
SOLUTION: Relating to a method and a system for analyzing a substrate (for example, 120), a step for scanning the substrate (for example, 120) is composed by generating a strength signal representing a general appearance of a wafer (for example, 120). As other elements contributing to the strength signal, chemical composition and electric state of a feature scanned on the substrate (for example, 120) may be listed. For evaluation of the substrate (for example, 120), the scanned signal is compared to a reference signal for correlation. Further, the method and system may be applied to a method for manufacturing a wafer (for example, 120) for improved manufacture quality of a product.
