Filed: 1994-09-12
Abstract: PURPOSE: To reduce the intensity of electric field for starting light emission by performing thermal treatment in gas atmosphere containing carrier gas composed of at least one of hydrogen gas, a VIb group hydrogen compound and inert gas as well as the simple substance gas of a decomposed VIb group. CONSTITUTION: A glass substrate, after layers up to a luminous layer is formed thereon, is immediately placed on a substrate holder in a thermal treatment chamber 11. After the chamber 11 is evacuated and gas is discharged therefrom at temperature lower than thermal treatment temperature, carrier gas is introduced to the chamber 11 for raising the temperature thereof. Then, a valve is selected to allow the carrier gas to pass a bubbler 19 before a temperature rise to target thermal treatment temperature. In this case, a decomposing heater 12 is heated up to the target thermal treatment temperature. An EL substrate 10, after heated up to the target thermal treatment temperature, is held at that temperature level over the preset time and, then, the carrier gas is changed to hydrogen gas or hydrogen sulfide unable to pass the bubbler 19.  After the exchange of gas, the substrate 10 is kept at a constant temperature level and, then, this temperature level is lowered to room temperature. At this process, low luminous voltage and high brightness characteristics can be provided by specifying the carrier gas.
