Disclosed are a film having codes recorded thereon, a reader used to recognize the film having the codes recorded thereon, and electronic equipment including a display device to which the film having the codes recorded thereon is attached. The reader includes a light emitting part irradiating light having a first wavelength onto a film surface printed with a code by using a predetermined fluorescent material, and a light receiving part receiving only a light having a second wavelength radiated by the predetermined fluorescent material if the light having the first wavelength is irradiated on the code. The reader recognizes the codes together with a screen when a code pattern is printed on the surface of the transparent material and the transparent material is attached on the surface of a display part provided in the electronic equipment.

A method of forming fine patterns of a semiconductor device according to a double patterning process that uses acid diffusion is provided. In this method, a plurality of first mask patterns are formed on a substrate so as to be separated from one another. A capping film including an acid source is formed on sidewalls and an upper surface of each of the plurality of first mask patterns. A second mask layer is formed on the capping films. A plurality of acid diffused regions are formed within the second mask layer by diffusing acid obtained from the acid source from the capping films into the second mask layer. A plurality of second mask patterns are formed of residual parts of the second mask layer which remain in the first spaces after removing the acid diffused regions of the second mask layer.

A chemically-amplified photoresist composition includes a polymer resin, a photo acid generator (PAG), and a thermal acid generator (TAG), where a thermal deprotection temperature of the polymer resin is greater than an acid generation temperature of the TAG. The photoresist composition may be utilized in a photolithography process which includes subjecting a layer of the photoresist composition to photon exposure which causes the PAG to decompose into acid, subjecting the photon-exposed layer of the photo resist composition to a heat treatment which causes the TAG to decompose into acid, and subjecting the heat-treated layer of photoreist composition to a post-exposure bake (PEB) at a temperature which is greater than the temperature of the heat treatment.

A method of forming fine patterns in a semiconductor device through a double photo lithography process. A layer to be etched and a hard mask layer are sequentially formed on a semiconductor substrate. A first photo resist pattern is formed on the hard mask layer. A first hard mask layer pattern is formed by etching the hard mask layer using the first photo resist pattern. After the first photo resist pattern is removed, a second photo resist pattern is formed on the resultant structure. A second hard mask layer pattern is formed by etching the first hard mask layer pattern using the second photo resist pattern. The layer to be etched is then etched using the second hard mask layer pattern after the second photo resist pattern has been removed, resulting in patterns have line edges without rounding.

Design rules for circuit patterns of a semiconductor device are identified, and schematic layouts of the circuit patterns are generated according to the design rules. Lithography friendly layout (LFL) circuit patterns are generated from the schematic layouts. Target layout circuit patterns are generated from the LFL circuit patterns. Optical proximity effect correction (OPC) is performed on the target layout circuit patterns to generate OPC circuit patterns. A mask is fabricated from the OPC circuit patterns, and may be used fabricate a semiconductor device.
