【発明の属する技術分野】
本発明は、有機ELなどの表示パネル等の薄膜形成装置、薄膜形成方法及び薄膜形成体に関するものである。
【0002】
【従来の技術】
例えば有機ELなどの表示パネルは、ガラス基板などの基板の表面に発光層や注入層などの高分子有機材料から成る薄膜を形成して製造される。かかる薄膜は、一般に、ノズルなどの塗布部から塗布液(高分子有機材料液)を吐出しながら、塗布部を基板の表面に沿って相対的に水平移動させることにより塗布して形成される。塗布液は、一般に、溶質と溶媒の混合液または溶質が溶媒に溶けている溶液(以下、混合液という)であり、溶媒が蒸発することにより基板の表面で固化する(例えば、(特許文献1)参照。)。
【0003】
図6は、従来方法により基板に塗布液を塗布して薄膜を形成した薄膜形成体の平面図である。薄膜形成体1は、塗布部を基板2の表面に沿って相対的に移動させて基板2の表面に塗布液を薄く塗布し、これを固化させて薄膜3が形成されている。基板に塗布された塗布液は、一般に、ホットプレートで加熱したり、赤外線を照射したり、超音波を付与するなどして溶媒の蒸発が促進され、固化して薄膜となる。

【発明が解決しようとする課題】
しかしながら従来方法では、塗布部が塗布開始位置aから塗布終了位置bまで相対的に移動して塗布動作が終了し、そこで塗布部を下降させて基板から分離する際に、塗布終了位置bで薄膜(塗布液)の盛上り部3a(図6でハッチングを付した部分)が生じやすく、特にその中央部分にスポット的に更なる肉厚部3a’を生じやすいという問題点があった。このように薄膜が縁部(塗布終了位置b)で局部的に盛上ると輝度ムラや色度ムラなどの発光ムラが発生しやすく、また薄膜の劣化寿命も縁部でばらついてしまうという問題点があった。
【0006】
そこで本発明は、薄膜の縁部(塗布終了位置)での盛上りを解消し、基板に均一な厚さのフラットな薄膜を形成できる薄膜形成装置、薄膜形成方法及び薄膜形成体を提供することを目的とする。
【0007】
【課題を解決するための手段】
本発明の薄膜形成装置は、基板の表面に薄膜を形成する薄膜形成装置であって、基板の表面に沿って相対的に移動しながら塗布液を吐出する塗布部と、塗布終了位置において前記塗布部を基板に対して相対的に下降させる下降手段とを備えた。
【0008】
また本発明は、基板の表面に沿って塗布液の塗布部を相対的に移動させて基板の表面に薄膜を形成する薄膜形成方法であって、塗布終了位置において前記塗布部を徐々に下降させるようにした。
【0009】
本発明によれば、薄膜の縁部(塗布終了位置)での盛上りを解消し、基板に均一な厚さのフラットな薄膜を形成できる薄膜形成装置、薄膜形成方法及び薄膜形成体を実現できる。
【0010】
【発明の実施の形態】
(実施の形態1)
図1は本発明の実施の形態1における薄膜形成装置の側面図、図2は本発明の実施の形態1における薄膜形成装置の塗布部の斜視図、図3は本発明の実施の形態1における薄膜形成装置の塗布部の部分拡大断面図、図4(a)は本発明の実施の形態1における薄膜形成体の平面図、図4(b)は本発明の実施の形態1における薄膜形成体の断面図である。
【0011】
図1において、10はガラス基板などの基板であり、保持体11に保持されて塗布部20の上方に位置している。保持体11は、真空吸着手段(図示せず)などの保持手段により、その下面に基板10を水平な姿勢で吸着保持している。保持体11の上面にはナット12が装着されており、ナット12には水平な送りねじ13が螺入されている。送りねじ13はモータ14に駆動されて回転する。
【0012】
モータ14の駆動により送りねじ13が回転すると、基板10を保持する保持体10は送りねじ13に沿って水平方向へ移動し(矢印A)、基板10も同方向へ移動する。すなわち、保持体11、ナット12、送りねじ13、モータ14は、塗布部20を基板10の表面に沿って相対的に水平方向に移動させる移動手段となっている。なお静止した基板10に対して塗布部20を水平方向に移動させてもよい。
【0013】
次に、図1〜図3を参照して塗布部20を説明する。塗布部20の本体21にはスリット22が形成されている。スリット22は本体21の上下に貫通するように形成されており、その下部はジョイント23、管路24を通じて貯溜部25に接続されている。貯溜部25に貯溜された塗布液(高分子有機材料液)26は、管路24に設けられた塗布液供給・吸引手段であるポンプ27によりスリット22へ送られる。
【0014】
本体21にはナット30が装着されており、ナット30には垂直な送りねじ31が螺入されている。モータ32により送りねじ31が正逆回転すると、本体21は上下動する(矢印B)。すなわちナット30、送りねじ31、モータ32は、塗布部20を基板10に対して相対的に上下動させる上下動手段となっている。なお塗布部20に対し、基板10を上下動させてもよい。また本体21には、振動付与手段としての超音波振動器33が装着されている。超音波振動器33が駆動すると、本体21は水平方向へ振動する(矢印C)。
【0015】
この薄膜形成装置は上記のような構成より成り、次にその動作を説明する。図1において、基板10の下面を塗布部20の上面に近接させ、モータ14を駆動して基板10を塗布部20に対して塗布開始位置aから塗布終了位置bまで水平方向に移動させる(矢印A)。このとき、ポンプ27を駆動して貯溜部25の塗布液26をスリット22へ送り、スリット22の上端から吐出させて基板10の下面に塗布する。
【0016】
本体21が塗布終了位置bまできたならば(図3(a))、ポンプ27による塗布液26の送給を停止し、モータ32を駆動して送りねじ31を回転させ、塗布部20を徐々にゆっくり下降させる(矢印B)。すなわち、ナット30、送りねじ31、モータ32は、塗布部20を基板10に対して相対的に下降させる下降手段となっている。すると上記従来方法のように塗布終了位置bに盛上り部や肉厚部を生じることなく本体21の上端部(スリット22の上端開孔部)は基板10の下面に塗布された塗布液26からきれいに分離される(図3(b))。望ましくは、この下降の際、超音波振動器33を駆動し、本体21を横方向Cへ振動させることにより、塗布液26の糸引きを防止し、塗布部20の下降とともに塗布液26が下方へ垂れ下るのを防止する。以上のようにして基板10に塗布された塗布液26には、赤外線ランプなどの固化手段(図外)により溶剤の蒸発が促進されて固化される。図3は、このようにして製造された薄膜形成体9を示している。なお一般に、基板には薄膜は多層に形成されるので、上記した薄膜の形成作業は複数回繰り返される。
【0017】
(実施の形態2)
図5は本発明の実施の形態2における薄膜形成装置の塗布部の部分拡大断面図である。実施の形態2は、塗布終了位置における塗布部の基板に対する相対的な上下動作が相違しており、装置の構成は実施の形態1と同じである。
【0018】
塗布部20が塗布終了位置bまで相対的に移動してきたならば(図5(a))、モータ32をわずかに逆回転させて塗布部20を基板10に対してわずかに相対的に上昇させ(矢印D)、そこで塗布液吸引手段であるポンプ27を逆駆動して塗布終了位置bに塗布された塗布液26をわずかに吸い込み(図5(b))、次いで塗布部20を下降させて基板10から分離する。この場合も、望ましくは、この下降の際に超音波振動器33を駆動し、本体21を横方向Cへ振動させる。すると上記従来方法のように塗布終了位置bに盛上り部や肉厚部を生じることなく本体21の上端部(スリット22の上端開孔部)は基板10の下面に塗布された塗布液26からきれいに分離され(図5(c))、図4に示す薄膜形成体9が得られる。

FIG.
[0011]
In FIG. 1, reference numeral 10 denotes a substrate such as a glass substrate, which is held by a holder 11 and located above the coating unit 20. The holding body 11 suction-holds the substrate 10 on its lower surface in a horizontal posture by holding means such as vacuum suction means (not shown). A nut 12 is mounted on the upper surface of the holding body 11, and a horizontal feed screw 13 is screwed into the nut 12. The feed screw 13 is driven by a motor 14 to rotate.
[0012]
When the feed screw 13 is rotated by the drive of the motor 14, the holder 10 holding the substrate 10 moves in the horizontal direction along the feed screw 13 (arrow A), and the substrate 10 also moves in the same direction. That is, the holder 11, the nut 12, the feed screw 13, and the motor 14 serve as moving means for moving the coating unit 20 relatively horizontally along the surface of the substrate 10. The application unit 20 may be moved in the horizontal direction with respect to the stationary substrate 10.
[0013]
Next, the coating unit 20 will be described with reference to FIGS. A slit 22 is formed in the main body 21 of the application section 20. The slit 22 is formed so as to penetrate the body 21 up and down, and the lower part thereof is connected to the storage part 25 through the joint 23 and the pipe 24. The coating liquid (polymer organic material liquid) 26 stored in the storage section 25 is sent to the slit 22 by a pump 27 that is a coating liquid supply / suction unit provided in the pipe 24.
[0014]
A nut 30 is mounted on the main body 21, and a vertical feed screw 31 is screwed into the nut 30. When the feed screw 31 is rotated forward and backward by the motor 32, the main body 21 moves up and down (arrow B). That is, the nut 30, the feed screw 31, and the motor 32 serve as a vertical moving unit that moves the coating unit 20 up and down relatively to the substrate 10. The substrate 10 may be moved up and down with respect to the coating unit 20. Further, the main body 21 is provided with an ultrasonic vibrator 33 as a vibration applying means.

At this time, the pump 27 is driven to send the coating liquid 26 in the storage unit 25 to the slit 22, and the liquid is discharged from the upper end of the slit 22 and applied to the lower surface of the substrate 10.
[0016]
When the main body 21 reaches the coating end position b (FIG. 3A), the supply of the coating liquid 26 by the pump 27 is stopped, the motor 32 is driven to rotate the feed screw 31, and the coating section 20 is gradually moved. (Arrow B). That is, the nut 30, the feed screw 31, and the motor 32 are lowering means for lowering the coating unit 20 relatively to the substrate 10. Then, the upper end of the main body 21 (the upper opening of the slit 22) is formed from the coating liquid 26 applied to the lower surface of the substrate 10 without forming a raised portion or a thick portion at the coating end position b as in the conventional method. It is clearly separated (FIG. 3 (b)). Desirably, at the time of this descent, the ultrasonic vibrator 33 is driven to vibrate the main body 21 in the lateral direction C, thereby preventing the stringing of the coating liquid 26 and lowering the coating liquid 26 with the lowering of the coating unit 20. Prevent sagging. The coating liquid 26 applied to the substrate 10 as described above is solidified by solidifying means (not shown) such as an infrared lamp by evaporating the solvent. FIG. 3 shows the thin film-formed body 9 manufactured in this manner. In general, a thin film is formed on a substrate in multiple layers, and thus the above-described thin film forming operation is repeated a plurality of times.
