Abstract
The invention provides a non-destructive inspection method for a selectively grown film and a manufacturing method of a semiconductor device for providing a simple and convenient process control and throughput improvement. The method comprises forming a pattern in which selectively grown areas are closely arranged on a wafer for manufacturing an LSI, determining the film thickness and the composition of the selectively grown layer by analyzing optical constant data for the entire pattern, and feeding back the result to the next batch thereby conducting process control.
Claims3
A method for manufacturing a semiconductor device on a semiconductor wafer, comprising:
- forming a dielectric film on a surface of a semiconductor substrate;
- forming a window in the dielectric film through which a portion of the surface of the semiconductor substrate is exposed;
- growing a semiconductor in the window;
- determining at least one of thickness and composition of a thin film, which is grown within at least one trench formed by etching through plural substances exposed on the wafer by using a measurement pattern formed on the wafer, by comparing at least one physics characteristic of the wafer before and after the film is formed;
- and
- adjusting at least one growth condition for making the thin film of next batch based upon the comparing result.
