Abstract: A resin composition, a cured layer, a manufacturing method of a cured layer and an etching method are provided. The resin composition includes a resin (A), a crosslinking agent (B) and a solvent (C). The resin (A) includes a structure represented by the following Formula (A-1). The crosslinking agent (B) includes a polymer including a first structural unit represented by the following Formula (B-1) and a second structural unit represented by the following Formula (B-2). Based on a usage amount of the resin (A) being 100 parts by weight, a usage amount of the crosslinking agent (B) is 60 parts by weight to 150 parts by weight, and a usage amount of the solvent (C) is 2400 parts by weight to 99900 parts by weight. In Formula (A-1), Formula (B-1) and Formula (B-2), the definition of each substituent is the same as defined in the specification.

Abstract: A resin composition and a cured film are provided. The resin composition includes a resin (A), a crosslinking agent (B), a surfactant (C), an additive (D) and a solvent (E). The resin (A) includes at least one of a phenol-based resin (A-1) and a polystyrene resin including a hydroxyl group (A-2). The additive (D) includes a fluoro-based phenol (D-1), a polyhydroxyphenol resin (D-2), a compound including an epoxy group (D-3), a polyether resin (D-4), a thermal acid generator including a sulfonate ion (D-5), or a combination thereof.

Abstract: An etchant composition, a tackifier, an alkaline solution, a method of removing polyimide and an etching process are provided. The etchant composition includes a tackifier (A) and an alkaline solution (B). The tackifier (A) includes a resin containing a hydroxyl group (a), a surfactant (b) and a first solvent (c1). The alkaline solution (B) includes an alkaline compound (d) and a second solvent (c2).

Abstract: An interactive data processing system and/or method is a management tool for a manufacturing plant including a shop floor control system. A server contains a data engine for extracting data, a load and transform data unit, and a database management storage unit. Data from the shop floor control system is supplied to the data engine in the server. The data engine can run the shop floor control system. The data engine supplies data received from the shop floor control system to the load and transform data unit. The load and transform data unit supplies data to the database management storage unit where the data is stored in a disk storage unit in storage space allocated to a conventional database management system employed for the purpose of management of data. The database management storage unit supplies data to an interactive graphic user interface.
