ETCHING APPARATUS AND ETCHING METHOD

摘要

An etching apparatus and an etching method are provided to need no work for sealing the circumference of glass and prevent the waste of an expensive etchant. An etching apparatus includes: an etching chamber(100) in which glass(400) is etched; a cassette(200) which fixes the circumference of the glass and has many fixation units capable of vertically positioning glass within the etching chamber; and a spray device(300) which sprays an etchant(500) on the upper part of the vertically positioned glass to etch the surfaces of the glass uniformly. An etching method includes the steps of: sealing and fixing the circumference of glass using many fixation units provided in the cassette; transferring the cassette to the inside of the etching chamber to place the glass vertically in the etching chamber; moving the spray device to the upper part of the glass, and spraying the etchant on the sides of the glass; and etching the surface of the glass uniformly by making the sprayed etchant flow down to form a water film.
