Abstract
A sinusoidal full or half resist pattern (3) is formed by a holographic exposure method in a photoresist layer (2) formed on a substrate (1) of glass or the like. After this, the substrate (1) is irradiated obliquely backward of the blaze direction with an ion beam by using an etching gas having a selection ratio (i.e., the etching rate of the substrate to the etching rate of the photoresist) less than 1. By executing the ion beam etching till the resist pattern (3) completely disappears, the sinusoidal grating grooves of the resist pattern (3) are transferred to the substrate thereby to form the pattern of a grating groove (4) having a saw-tooth section. A small blaze angle can be formed by lowering the etching rate of the substrate (1). In this case, too, by applying the ion beam obliquely not forward but backward of the blaze direction, the edge angle backward of the blaze angle across the blaze face can be reduced to enhance the diffraction efficiency.
