摘要:
In a thinner composition and a method of forming a photosensitive film, the thinner composition includes about 50 to about 90% by weight of propylene glycol monomethyl ether acetate, about 1 to about 20% by weight of propylene glycol monomethyl ether, about 1 to about 10% by weight of γ-butyrolactone, and about 1 to about 20% by weight of n-butyl acetate. The thinner composition may have a proper volatility and an improved ability to dissolve various types of photosensitive materials, and thus the thinner composition may be usefully employed in an edge bead rinse process, a rework process or a pre-wetting process.

Provided is a method of selecting a white Gaussian noise sub-band using singular value decomposition (SVD). The method includes selecting a first frequency band, verifying whether a signal is included in the selected first frequency band, determining the first frequency band as a target measurement frequency when the signal is not included in the selected first frequency band, and measuring a background radio noise in the determined target measurement frequency.

A digital photographing system includes a smart mount that includes lenses, a shutter, an image sensor, and an image processor, combined with a camera body or a mobile terminal device. A method of operating the digital photographing system is provided. The digital photographing system includes a lens; a smart mount that captures and processes an image of an object input via the lens; and a body that displays, modifies, stores, or deletes the image captured and processed by the smart mount.
摘要:
A photoresist composition, a method of forming a pattern using the photoresist composition, and a method of manufacturing a display substrate are disclosed. A photoresist composition includes an alkali-soluble resin, a quinone diazide-based compound, a multivalent phenol-based compound, and a solvent. Therefore, photosensitivity for light having a wavelength in a range of about 392 nm to about 417 nm may be improved, and reliability of forming a photo pattern and a thin film pattern using the photoresist composition may be improved.
