Abstract:
A method of manufacturing an alignment mark for aligning a pattern of a first pattern layer and a pattern of a second pattern layer in a predetermined layout when the first pattern layer and the second pattern layer are layered together on a wafer, comprising:forming a first alignment mark in a predetermined region of the first pattern layer during the formation of the first pattern layer; forming a second alignment mark by cutting the second pattern layer at a predetermined position thereof on the basis of the first alignment mark; providing a protective layer for protecting the second alignment mark; forming a predetermined pattern in a pattern forming region of the second pattern layer by using the first alignment mark; forming resist to a thickness at which the second alignment mark is filled in thereby; and removing the resist and exposing the second alignment mark after the predetermined pattern has been formed in the pattern forming region of the second pattern layer.
