摘要:
A greatly improved printing screen used for screen printing is provided in respect of the durability in printing, resistance against solvents and antistatic performance based on a mesh of polyester or nylon filaments. According to the invention, the base mesh is subjected to exposure to low temperature plasma of an inorganic gas prior to coating with a photosensitive resin composition in the form of an aqueous emulsion. When the plasma-treated mesh is coated, prior to coating with the photosensitive resin emulsion, with a surface active agent or when the photosensitive resin emulsion is admixed with a surface active agent, further improvement can be obtained in the antistatic performance of the screen. When a base screen dyed in yellow is used, the drawbacks caused by halation in the pattern-wise exposure of the screen to light can be greatly reduced.

A sintered rare-earth magnet contains specific amounts of R (two or more rare-earth elements, with Nd and Pr being essential), boron (B), M1 (one or more element selected from Al, Si, Cr, Mn, Cu, Zn, Ga, Ge, Mo, Sn, W, Pb and Bi) and M2 (one or more element selected from Ti, V, Zr, Nb, Hf and Ta), with the balance being T (one or more element selected from Fe and Co). The magnet has a R2Ti4B main phase and, over an area fraction of more than 0% and up to 10%, an R2(T, M1)17 phase covered with an R6(T, M1)14 phase and an R-rich phase. Two magnetization inflection points—a first knickpoint on a low magnetic field side and a second knickpoint on a high magnetic field side—are present in the second quadrant of the magnetic polarization curve at 23° C.

The present invention is a method for forming a resist underlayer film, including the steps of: (i) coating a substrate with a composition for forming a resist underlayer film containing a metal compound having a metal-oxygen covalent bond and an organic solvent; (ii) forming a cured film by heating the coated substrate at a temperature of 100° C. or higher and 600° C. or lower for 10 seconds to 7,200 seconds for curing; and (iii) forming a resist underlayer film by irradiating the cured film with plasma, where a compound containing at least one crosslinking group represented by the following general formulae (a-1) to (a-4), (b-1) to (b-4), and (c-1) to (c-3) is used as the metal compound. This provides: a method for forming a resist underlayer film that contains metal and that exhibits both high filling property and high dry etching resistance; and a patterning process using the method.
摘要:
The negative-tone molecular resist composition comprises an onium salt containing a cation having a cyclic ether site and an organic solvent has a high sensitivity and forms a resist film with improved resolution and LWR when processed by photolithography using high-energy radiation. The molecular resist composition of the invention meets both high sensitivity and high resolution and is improved in LWR when processed by photolithography using high-energy radiation, especially EB or EUV lithography. The resist composition is quite useful for precise micropatterning.
