摘要:
The invention relates to a phase shift photomask in which the peripheral region portion of a phase shift layer is removed by a relatively simple procedure and which has no or little defect and is inexpensive, a blank therefor, and a process for fabricating them. The process includes the steps of forming phase shift layer 23 all over the surface of one side of transparent substrate 21, and immersing only the peripheral region of substrate 21 in etching solution 25 to etch away the peripheral region of phase shift layer 23, whereby phase shift layer 27 is confined within an area smaller than that of substrate 21.

摘要:
The present invention relates particularly to a process for producing phase shift layer-containing photomasks, which can produce phase shift photomasks through a reduced or limited number of steps to reduce or limit the incidence of phase shifter pattern deficiencies or other defects and at lower costs as well.For instance, a photomask blank of the structure that a substrate is provided thereon with an electrically conductive layer and a light-shielding thin film in this order is used to coat a starting material for spin-on-glass uniformly on a light-shielding pattern formed thereon. A pattern is directly drawn on the coated spin-on-glass layer with energy beams emanating from electron beam exposure hardware, etc., and the substrate is developed with a solvent after pattern drawing with energy beams to wash off an excessive spin-on-glass portion other than the spin-on-glass layer irradiated with the ionizing radiations. Finally, the post-development substrate is baked to form a phase shifter pattern.

An optically active, fluorine-containing carbonyl-ene product is produced by reacting a fluorine-containing α-ketoester with an alkene in the presence of a transition metal complex having an optically active ligand. There are Mode 1 of conducting this reaction in the absence of reaction solvent, Mode 2 of conducting this reaction in a solvent that is low in relative dielectric constant, and Mode 3 of conducting this reaction in a halogenated hydrocarbon-series solvent. In each of these three modes, it is possible to produce the optically active, fluorine-containing carbonyl-ene product with low cost.
