The phase shift layer contains niobium (Nb), and is made of a material containing one of tantalum (Ta), chromium (Cr), and ruthenium (Ru). A phase shift layer containing Nb and Ta has a relative reflectance of 5 to 20%, a phase shift layer containing Nb and Cr has a relative reflectance of 9 to 15%, and a phase shift layer containing Nb and Ru has a relative reflectance of 20% or more. The phase shift layer has a phase shift amount of 170 to 230°, and has a surface roughness of 0.5 nmRMS or less. It is possible to obtain excellent resolution when finally manufacturing a pattern of 7 nm or less by using a photomask manufactured using such a blankmask.

Abstract: The present invention relates to a composition for controlling plant diseases containing a limonene derivative as an active ingredient. In the present invention, the limonene derivatives have an effect of inhibiting the growth of Xanthomonas oryzae pv. Oryzae (Xoo), which is a pathogen mediating bacterial leaf blight, and Magnaporthe oryzae, which is a pathogen mediating rice blast, and it was confirmed in an experiment with respect to inhibition using volatility (i.e., in a state not being in direct contact with Xoo or M. oryzae) that the limonene derivatives have a growth inhibitory effect. Accordingly, the limonene derivatives have an inhibitory effect against the growth of Xoo and thus they can be effectively used as a composition for controlling plant diseases.
