摘要:
A resin composition which, in forming a fine pattern by a heat treatment of a resist pattern formed by using a photoresist, can be applied onto the resist pattern, can cause the resist pattern to smoothly shrink by heat treatment, and can be easily washed away by a treatment with an alkaline aqueous solution, and a method for efficiently forming a fine resist pattern using the resin composition are provided. The resin composition comprises a resin containing a hydroxyl group, a crosslinking component, and an alcohol solvent containing water in an amount of 10 wt % or less for the total solvent, wherein the alcohol in the alcohol solvent is a monovalent alcohol having 1 to 8 carbon atoms.

Provided is a filler for affinity chromatography having a high dynamic binding capacity for proteins and having excellent alkali resistance and storage stability. The filler for affinity chromatography of the present invention comprises a porous particle consisting of a copolymer of 40 parts to 99.5 parts by mass of (M-1) a methacryloyl group-containing vinyl monomer that contains a hydroxyl group and does not contain an epoxy group, 0.5 parts to 30 parts by mass of (M-2) an epoxy group-containing vinyl monomer, 0 parts to 59.5 parts by mass of (M-3) a methacryloyl group-containing vinyl monomer which is other than the monomers (M-1) and (M-2), and 0 parts to 25 parts by mass of (M-4) a vinyl monomer other than the monomers (M-1), (M-2) and (M-3) (with the proviso that the total amount of the contents of (M-1), (M-2), (M-3) and (M-4) is 100 parts by mass); ring-opened epoxy group obtainable by ring-opening of epoxy group that is contained in the copolymer; and ligand that is bound to the porous particle.

A resist pattern formation method includes providing a first positive-tone radiation-sensitive resin composition on a substrate to form a first resist layer. The first resist layer is selectively exposed and developed to form a first resist pattern. The first resist pattern is coated with a resist pattern insolubilizing resin composition which comprises a resin and an alcohol solvent, the resin having a hydroxyl group. The resist pattern insolubilizing resin composition is baked or cured with UV to insolubilize the first resist pattern in a developer and in a second positive-tone radiation-sensitive resin composition. The resist pattern insolubilizing resin composition is developed to form an insolubilized resist pattern. The second positive-tone radiation-sensitive resin composition is provided on the insolubilized resist pattern to form a second resist layer. The second resist layer is selectively exposed and developed to form a second resist pattern.

A ground fault detection circuit includes: a first switch circuit that connects/disconnects a first path between a positive bus bar and a ground potential section, the positive bus bar being connected to positive electrodes of secondary battery units through a field-effect transistor including a parasitic diode; a second switch circuit that connects/disconnects a second path between a negative bus bar and a ground potential section, the negative bus bar being connected to negative electrodes of the secondary battery units; and a ground fault detection unit that detects a ground fault of the positive bus bar or the negative bus bar based on an electric current flowing through the first path or the second path.
