A high frequency heating apparatus which heats a substrate by applying high frequency waves thereto. The high frequency heating apparatus includes a high frequency generator which generates high frequency to heat the substrate. The distance from the substrate to the high frequency generator is n/2*&#x3bb;, where n is a natural number ranging from 1 to 6, and &#x3bb; is the wavelength of the high frequency that is generated by the high frequency generator.

An apparatus for chemically toughening glass which can toughen the surface of the glass by inducing compressive stress on the glass surface through ion exchange and a method of chemically toughening glass using the same. The apparatus includes a chemical toughening bath which chemically toughens the glass; a transportation part which transports the glass from upstream of the chemical toughening bath through the chemical toughening bath to downstream of the chemical toughening bath; and a microwave generator disposed above the chemical toughening bath, the microwave generator radiating microwaves to the glass.

A method of cutting chemically toughened glass which is chemically toughened in a chemical toughening process of creating compressive stress in the surface of glass by exchanging first alkali ions in the glass with second alkali ions. The method includes the steps of applying a paste on a portion of the chemically toughened glass that is to be cut, heating the paste, and cutting the chemically toughened glass along the portion on which the paste is applied. The paste contains alkali ions. The ion radius of the alkali ions in the paste is smaller than an ion radius of the second alkali ions which substitute the first ions in the chemical toughening process.

An apparatus for measuring transmissivity of a patterned glass substrate. A beam radiator radiates a laser beam. A collimation lens collimates the laser beam radiated from the laser beam radiator. A beam expander expands a size of the laser beam collimated by the collimation lens. A detector has a light-receiving section, which receives the laser beam that has passed through the patterned glass substrate after having been expanded by the beam expander. A measuring instrument measures a transmissivity of the patterned glass substrate using the laser beam received by the detector.

An apparatus for manufacturing tempered glass. A transportation unit transports a glass substrate that is intended to be tempered. An ionizer ionizes alkali oxides in the glass substrate by radiating energy onto the glass substrate. A dielectric heating unit increases the temperature of the inner portion of the glass substrate in which the alkali oxides are ionized by the ionizer.
