Abstract:
A method for manufacturing a flat panel display and an apparatus for shaving an outer surface thereof are provided to etch selectively the required areas of a glass substrate while maintaining characteristics such as high productivity and uniform distribution. An apparatus for shaving an outer surface includes a chamber(280), a cassette(220), a plate(260), a supplier(230), and a storing tank(240). The chamber is used for executing the shaving of an outer surface therein. The cassette is used for moving a glass substrate. The plate installed in the chamber in a vertical direction includes nozzles for spraying etch liquid toward the outer surface of the glass substrate. The nozzles of the plate are used for etching one face of the glass substrate opposite to the plate. The supplier connected to the plate supplies the etch liquid. The storing tank installed in the chamber stores the etch liquid and supplies the etch liquid to the supplier.
Abstract:
A method for manufacturing a flat panel display and an apparatus for shaving an outer surface thereof are provided to reduce mechanical stress on glass substrates during etching by naturally slipping etch liquid on the glass substrates. An apparatus for shaving outer surface includes a chamber(210), a cassette(230), a cassette controller(240), a nozzle unit(250), and a supply tank(260). The chamber is used for executing the shaving of an outer surface. The cassette is used for moving a glass substrate. The cassette controller tilts the glass substrate mounted on the cassette with respect to a horizontal plane by adjusting the position and angle of the cassette. The nozzle unit installed at an upper portion of the chamber includes nozzles for spraying the etch liquid. The supply tank supplies the etch liquid to the nozzle unit. The cassette controller adjusts the position and angle of the cassette so as to correspond to the glass substrate and nozzles one by one.
Abstract:
An etching apparatus of a substrate is provided to prevent damage of a thin film transistor and maintain the strength thereof by simultaneously etching one side of a first display panel or second display panel. An etch array substrate includes a pad(72) with a display panel attached to one side of the pad, and a support plate(70) provided on both sides of the pad. One side of the display panel is etched by an etchant(92), and the etched array substrate and the etchant are received in a container(90). The display panel has a thin film transistor substrate(50) and a color filter substrate(40), and the pad is attached to any one of the thin film transistor substrate and the color filter substrate.

PURPOSE: An apparatus for cleaning a semiconductor device is provided to improve productivity and yield of the semiconductor device, by uniformly maintaining the density of cleaning solution in a cleaning bath at all times. CONSTITUTION: The semiconductor device to clean and the cleaning solution are contained in the cleaning bath(10). A compound supply source supplies a compound to the cleaning bath. An electrical conductivity measuring unit(60) measures the electrical conductivity of the cleaning solution in the cleaning bath, and supplies an electrical conductivity data signal corresponding to the measured electrical conductivity. A controller(70) controls the quantity of the compound supplied from the compound supply source to the cleaning bath in response to the electrical conductivity data signal.
