Problems solved by technology
This results in a short channel length for low drain-to-source on-resistance (Rds on ) becomes difficult
Furthermore, the thin gate electrode used prevents itself from acting as a hard mask, further compromising the process control of forming the channel well

Embodiment Construction
[0062] Embodiments of the present invention will be specifically described below with reference to the drawings.
[0063] First, the structure of the fluorescent display tube of this embodiment will be described. figure 1 Among them, figure number 1 (1A) is a fluorescent display tube, 2 is an anode substrate, 4 (4b) is a wiring conductor (grid wiring), 5 is an insulating layer, 8 is a control electrode (mesh grid), 21 22 is the second fixing material, and 23 is the sliding layer. On the insulating layer 5, the anode conductor layer 6, the phosphor layer 7, etc. are originally placed (see image 3 ), but in figure 1 omitted.
[0064] Such as figure 1 As shown, a fluorescent display tube 1A includes a built-in control electrode 8 fixed to an insulating layer 5 formed on an anode substrate 2 made of an insulating substrate such as glass. The mesh grid 8 serving as the control electrode is made of conductive metal or the like, and both ends 31a, 31b are bent in a substantia...

PROBLEM TO BE SOLVED: To provide a vacuum fluorescent display which adds tension to the control electrode by restraining it from being deformed after firing, thereby preventing occurrence of display variations to improve a yield and also facilitate manufacture, and a method for manufacturing the same.SOLUTION: A vacuum fluorescent display 1A includes an inside-fitted control electrode 8 which is secured on an insulation layer 5 of an anode substrate 2 by using a first fastening member 21 having prescribed fusion and solidification temperatures and a second fastening member 22 having a higher solidification temperature than the fusion temperature of the first fastening member 21, the control electrode 8 being electrically connected at one end 31a to grid wiring 4b by the first fastening member 21 and also stuck to the insulation layer 5 by the first fastening member 21 and the second fastening member 22, while being stuck at other end 31b of the control electrode 8 to the insulation layer 5 by the first fastening member 21 and the second fastening member 22. In the vacuum fluorescent display 1A, a slide layer 23 having fluidity at a temperature equal to or lower than the solidification temperature of the second fastening member 22 is formed between the first fastening member 21 on the other end 31b side of the control electrode 8 and the insulation layer 5.
Description
technical field [0001] The present invention relates to a fluorescent display tube capable of allowing thermal expansion of the control electrode, suppressing deformation of the control electrode after sintering, and applying tension to the control electrode during sintering of a fluorescent display tube provided with a built-in control electrode, and its manufacture. method. Background technique [0002] Fluorescent display tubes are self-illuminating display devices. Due to their high visibility and good environmental resistance, they are widely used in home appliances such as microwave ovens, AV products such as stereos, and automotive display devices such as car audio. Such as image 3 As shown, a general fluorescent display tube 1, which is also a kind of vacuum tube, has an anode substrate 2 composed of a glass substrate, etc., and a cover member 3 composed of a front panel 3a and a side panel 3b. The inner surface of the bottom 2 is laminated with a wiring conductor ...
