TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Process: The manufacture of article further involves selectively adhering composition for electrode, composition for semiconductor layer, composition for conductor layer, composition for transistor material and/or composition for resin layer, on the surface of lyophilic region and forming electrode, semiconductor layer, conductor layer, transistor material and/or resin layer.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation (disclosed): The liquid-repellant compound is prepared by introducing group (Cf) with respect to hydroxyl group of hydroxyl group-containing compound of formula (II) and esterifying using acid fluoride compound.    TECHNOLOGY FOCUS - POLYMERS - Preferred Composition: The polymer further has a unit (u2) having crosslinkable functional group and does not have group (Cf). The curable composition further contains solvent (E), radical polymerization initiator (D), fluorine-containing polyarylene prepolymer (A) having crosslinkable functional group and compound (B) having number average molecular weight of 140-5000, crosslinkable functional group, and does not have fluorine atom. Preferred Process: The prepolymer (A) is obtained by condensing and reacting fluorine-containing aromatic compound, phenol-type compound, and crosslinkable functional group-containing aromatic compound in presence of dehydrohalogenation agent. EXAMPLE - 9.3 g of 2-(4-((6-(2-hydroxy-2-methylpropanoyl)naphthalen-2-yl)sulfanyl)phenoxy)ethyl 2-methylprop-2-enoate and 4.2 g triethylamine were dissolved in 150 g tetrahydrofuran, 10.8 g 2-(1,1-difluoro-2-methyl-2-(1,1,2,2-tetrafluoropropoxy)propoxy)-2,2-difluoroacetyl fluoride was added to the resultant solution, stirred and reacted at 0 degrees C or more for 1 hour to obtain reaction solution. The obtained reaction solution was extracted with ethyl acetate for 3 times and the resultant organic phase was dried under vacuum, to obtain 14.5 g 2-(4-((6-(2-((3-(1,1-difluoro-2-methyl-2-(1,1,2,2-tetrafluoropropoxy)propoxy)-3,3-difluoro-2-oxopropanoyl)oxy)-2-methylpropanoyl)naphthalen-2-yl)sulfanyl)phenoxy)ethyl 2-methylprop-2-enoate.
