Description

利用喷墨印刷技术制造有机半导体器件的方法及器件和利用该器件的系统 Inkjet printing techniques utilizing an organic semiconductor device manufacturing method and device and a system using the device

发明的背景1、发明的领域本发明一般涉及有机半导体器件,特别涉及利用喷墨印刷技术制造有机半导体器件的方法,及器件和使用该器件的系统。 1 Background of the invention Field of the Invention The present invention generally relates to an organic semiconductor device, particularly relates to the use of inkjet printing techniques the method of manufacturing an organic semiconductor device, and devices and systems of the device.

2、相关技术的介绍例如硅等无机半导体一般用于制造现代半导体和光子器件。 2, description of the related art is generally an inorganic semiconductor such as silicon for fabricating modern semiconductor and photonic devices. 这些无机半导体器件的处理可能是复杂和高成本的,一般包括例如晶体生长、切片和晶片的抛光及在晶片上形成集成电子电路等工艺步骤。 The treatment of the inorganic semiconductor devices can be complex and costly, process steps typically include, for example, crystal growth, slicing and polishing the wafer on the wafer and formed an integrated electronic circuit. 比较起来,常规聚合物(有时称作塑料)较容易加工。 In comparison, conventional polymer (sometimes referred to as plastic) more easily processed. 例如,传统塑料部件的制造包括例如将熔化的塑料材料注入模具等较简单的工艺步骤。 For example, conventional manufacturing plastic components including, for example molten plastic material is injected relatively simple process steps mold. 常规聚合物还具有柔韧且重量轻等特点,可以大表面积制造。 Conventional polymers also have a flexible and light weight, a large surface area can be manufactured. 然而,常规塑料不是半导电的,因此不能用于制造半导体器件。 However, not a conventional plastic semi-conductive, and therefore can not be used for manufacturing a semiconductor device.

共轭聚合物是一种结合了半导体的电学和光学特性及常规塑料的可加工性的有机材料。 Conjugated polymer workability is a combination of an organic material and the electrical and optical characteristics of a conventional semiconductor plastic. 共轭聚合物的半导电性源于形成在例如聚(亚苯基亚乙烯基)、聚噻吩(PT)、聚(2-甲氧基-5-(2′-乙基-己氧基)-1,4-亚苯基亚乙烯基(MEH-PPV)等含碳化合物中的离域π轨道。与常规聚合物不同,共轭聚合物含有使材料半导电而不绝缘的双键。共轭聚合物具有低成本加工的优点,柔韧、重量轻,并具有常规聚合物的可大规模加工性,而且具有硅的普通半导电特性。 Conjugated semiconductive polymer is formed from, for example, poly (phenylene vinylene), polythiophene (PT), poly (2-methoxy-5- (2'-ethyl - hexyloxy) 1,4-phenylene vinylene (MEH-PPV) and other carbon-containing compounds in the delocalized π orbital. different from the conventional polymers, a material containing a conjugated polymer semiconducting insulation without double bonds. total conjugated polymer has the advantage of low-cost processing, flexibility, light weight, and can be conventional polymers having a large-scale processing, but also an ordinary silicon semiconducting properties.

共轭聚合物器件一般利用旋涂法制造。 Conjugated polymer devices are typically manufactured by a spin coating method. 使含有大滴液态共轭聚合物的基片绕轴高速旋转,使液态共轭聚合物向外流,从而用材料薄膜涂敷基片,这种旋涂法利用了聚合物溶液加工性的优点。 So that large droplets of liquid substrate comprises a conjugated polymer around the shaft rotates at high speed, the liquid to drain conjugated polymer, which takes advantage of the workability of the polymer solution coating a substrate with a thin film material, such a spin coating method. 然而,该方法仍存在与旋涂有关的缺点。 However, this method still drawbacks associated with the spin-coating. 由于多数液态共轭聚合物飞出了基片,没涂在基片表面上,旋涂造成了溶液的浪费。 Since the majority of the liquid fly out of the conjugated polymer substrate, not coated on the surface of the substrate, spin coating resulting in a waste solution. 此外,由于任何突出物都会在液态有机材料散布于基片表面上时产生阴影效应,所以旋涂法对基片表面上的灰尘或其它缺陷很敏感,会在缺陷的后面留下较薄的有机材料径向痕迹。 Further, since no protrusion will create a shadow effect in the liquid organic material is spread on the substrate surface, a spin coating method is very sensitive to dust on the substrate surface or other defects, it will be left behind in the organic thin defect radial material traces.

旋涂期间不容易控制的液态共轭聚合物流还无法形成希望的图形,限制了共轭聚合物的商业应用。 During spin coating pattern is not easy to control the flow of liquid conjugated polymer can not form the desired, limited the commercial applications of conjugated polymers. 例如,夹在两电极间的发光共轭聚合物可用于制造LEDs和发光标志(light-emitting logos,LELs),但旋涂形成的共轭聚合物未构图单层将这种器件限制为单色器件,而且需要对电极进行构图。 E.g., sandwiched between two electrodes of the light emitting conjugated polymers can be used to manufacture LEDs and the light emitting flag (light-emitting logos, LELs), but formed by spin coating a monolayer unpatterned conjugated polymer such devices will be limited to a monochromatic devices, but also the electrode is patterned. 另外,由于共轭有机材料中的双键会因光刻工艺而被破坏,所以一般用于形成构图电极的光刻技术无法用于构图共轭聚合物层。 Further, since the organic material due to conjugated double bonds is destroyed by a photolithography process, it is generally used in a photolithography technique can not be used for forming patterned electrode patterned layer of a conjugated polymer.

另一类有机半导体材料是共轭小有机分子类。 Another class of organic semiconductor material is a conjugated small organic molecules classes. 这里将共轭有机化合物(有机物)定义为包括聚合物(每个分子链具有两个以上重复单元的有机物)和小有机分子(单个分子构成的有机物)。 Here conjugated organic compound (organic) is defined to include polymers (organic material having per molecule chain of two or more repeating units) and small organic molecules (organic molecules in single). 小有机分子具有与共轭聚合物类似的物理(电学和光学)性质,但利用不同的加工技术。 Small organic molecules having conjugated polymer similar physical (electrical and optical) properties, but with different processing techniques. 有机分子通常在超高真空环境中,利用热升华法加工,形成所希望的薄膜,一般膜厚约100nm。 The organic molecules typically an ultra high vacuum environment, the method using the sublimation process, forming the desired thin film, typically a thickness of about 100nm. 小有机分子一般采用与共轭聚合物类似的器件结构,即有机薄膜夹有两电极之间。 Small organic molecule and a conjugated polymer is generally used a similar device structure, i.e., an organic thin film sandwiched between two electrodes. 有机薄膜的构图可利用孔板(shadow mask)完成,但该方法需要精确地对准孔板,是一种速度慢且成本高的工艺。 The organic thin film may be patterned using a perforated plate (shadow mask) is completed, but the method requires precise alignment of the orifice plate, it is a slow and costly process. 另外,横向分辨率也受到了限制。 Additionally, lateral resolution is also limited. 有机分子也可利用常规的旋涂工艺加工,但该方法无法构图。 Organic molecules may be spin coating using conventional process technology, but the method can not be patterned. 一般通过将这些分子与主共轭聚合物混合来加工小有机分子,使混合物保留聚合物于膜形成方面的机械特性的优点。 These molecules are typically formed by the primary mixing the conjugated polymer processing small organic molecules, to retain the advantages of polymer in the mixture formation in the mechanical properties of the film. 图18a、18b和18c给出了适用于缓冲层和喷墨印刷淀积物的典型有机化合物的例子。 FIG. 18a, 18b and 18c are given for typical examples of the organic compound of the buffer layer and the ink jet printing deposits.

喷墨印刷(IJP)技术是桌面出版的普通技术,可用于高分辨率地淀积构图的共轭有机材料。 Ink-jet printing (the IJP) is a common technique desktop publishing technology, can be used for high-resolution patterning deposited a conjugated organic material. T. T. R Hebner等人在Applied PhysicsLetters(应用物理通讯)第72卷第519页(1998)的题为“用于有机发光器件的掺杂聚合物的喷墨印刷”一文中,已介绍了IJP在淀积构图的共轭有机物方面的应用,这里引用该文献。 "Inkjet printing for the doping of polymer organic light emitting device" R Hebner et al., Entitled Applied PhysicsLetters (Applied Physics Letters) 72, p. 519 (1998) is a paper, it has been introduced in the deposition IJP application of organic contaminants patterned conjugate, hereby incorporated by reference. 然而,为了利用现有的IJP技术,只能印刷含颜料的低浓度聚合物溶液。 However, in order to IJP prior art, only a low concentration of the polymer solution containing a printing pigment. 结果是形成了对于高质量半导体器件来说不适用的低劣薄膜。 Poor result is a high quality thin film for a semiconductor device is not applicable.

甚至在可以在下电极上淀积适当构图的共轭有机物时,仍存在其它问题。 Even when the proper composition can be deposited on the lower electrode conjugated organic material, there are still other problems. 由于IJP的点形成性,利用IJP印刷的有机膜会有许多针孔。 Since the dot-forming IJP using IJP printing organic film have many pinholes. 构图共轭有机物薄膜上的上电极材料淀积,会造成某些上电极材料通过针孔与下电极接触,产生造成使器件失效的短路。 Patterning the deposited electrode material on the conjugated organic film on, cause some electrode material in contact with the lower electrode through the pinholes, resulting in generation of short-circuit failure of the device.

优选实施方案的详细描述在对优选实施方案的以下介绍中,参考构成本发明一部分的各附图,图中以例示可以实现本发明的特定实施方案的方式显示。 Detailed Description of Preferred Embodiments In the following description of preferred embodiments, reference is made a part of each of the present invention, a specific embodiment of the embodiment illustrated in the figures may be implemented according to the present invention. 应理解,在不背离本发明优选实施方案的范围的情况下,可以利用其它实施方案,并且结构上也可以变化。 It should be understood, without departing from the scope of the preferred embodiment of the present invention, other embodiments may be utilized and structural changes may be.

共轭有机物具有低成本加工的优点,柔韧、重量轻,并具有常规有机物的可大规模加工性,而且具有无机半导体的一般半导电特性。 General characteristics of the semiconductive conjugated organic material has the advantage of low-cost processing, flexibility, light weight, and may be a conventional large-scale processing of organic and inorganic semiconductors. 图1示出了根据本发明一个实施方案的共轭有机半导体器件10。 Figure 1 shows an organic semiconductor device 10 according to one embodiment of the conjugate of the present invention. 在共轭有机半导体器件10中,利用常规淀积技术,在基片12上形成由金属或金属氧化物构成的第一电极14。 In the conjugated organic semiconductor device 10, using conventional deposition techniques to form a first electrode 14 made of a metal or metal oxide on the substrate 12. 基片12可以由例如玻璃、塑料、半导体晶片和其上具有薄绝缘层的金属板等固体材料、或例如塑料和其上具有薄绝缘层的金属箔等柔性材料构成。 The substrate 12 may be, for example, plastic or metal foil and the like having thereon a thin insulating layer is made of a flexible material such as a solid material such as glass, plastics, and semiconductor wafers on which a thin metal plate having an insulating layer. 在优选实施方案中,第一电极14由氧化铟锡(ITO)构成。 In a preferred embodiment, the first electrode 14 composed of indium tin oxide (ITO). 然后,利用旋涂法、热升华法、或其它常规施加方法,在第一电极14上,形成厚约1-1000nm的基本均匀的共轭有机缓冲层16。 Then, using a spin coating method, a sublimation method, or other conventional methods is applied, on the first electrode 14, forming a substantially uniform thickness of about 1-1000nm conjugated organic buffer layer 16. 然后,用IJP头18,在共轭有机缓冲层16上,至少印刷一层共轭有机淀积物20。 Then, the head 18 IJP, the conjugated organic buffer layer 16, at least one organic deposits 20 printing conjugate. 采用IJP是由于与旋涂不同,IJP能够印刷微米分辨率的共轭有机淀积物20,由于共轭有机淀积物20垂直喷涂于共轭有机缓冲层16的表面上,而不是水平流淌,所以,IJP对灰尘和基片缺陷较不敏感,并且在施加工艺期间不浪费更多材料。 IJP is due to the use of different spin coating, printing IJP-micron resolution can be conjugated organic deposit 20, since the conjugated organic deposits 20 perpendicularly sprayed on the surface of the conjugated organic buffer layer 16, rather than horizontal flow, Therefore, the IJP less sensitive to substrate defects and dust, and no more material is wasted during the application process.

如图2a所示,然后,利用常规金属淀积技术,在共轭有机淀积物20和共轭有机缓冲层16上,淀积第二电极22。 As shown in Figure 2a, and then, using a conventional metal deposition techniques, conjugated organic material 20 is deposited and a conjugated organic buffer layer 16, the second electrode 22 is deposited. 由于共轭有机缓冲层16绝缘性强,第二电极22和第一电极14间不会发生短路。 Since the organic buffer layer 16 insulating conjugated strong, short-circuiting the second electrode 22 and the first electrode 14 does not occur.

在图3a所示的本发明替代实施方案中,在第一电极14上直接利用IJP淀积共轭有机淀积物20。 The present invention shown in FIG. 3a an alternative embodiment, IJP directly deposited on the first electrode 14 is deposited organic conjugated 20. 然后,利用旋涂或其它常规施加方法,在共轭有机淀积物20和第一电极14上,形成共轭有机缓冲层16。 Then, by spin coating or other conventional application methods, the conjugate electrode 20 and the first organic material 14 is deposited, to form a conjugated organic buffer layer 16. 然后,利用常规金属淀积技术,在共轭有机缓冲层16上淀积第二电极22。 Then, using conventional metal deposition techniques, the deposition of the second electrode 22 conjugated on the organic buffer layer 16.

在图4a和5a所示的另外的替代实施方案中,可以形成多层共轭有机缓冲层16和多层共轭有机淀积物20,增大了垂直或三维尺寸,提高了半导体器件的功能密度。 Figure 4a functions further alternative embodiment shown in Figures 5a and may form a multilayer conjugated organic buffer layer 16 and multilayer conjugated organic deposits 20, increasing the vertical or three dimensions, improved semiconductor device density.

尽管图2a、3a、4a和5a示出了具有一个第一电极14和一个第二电极22的实施方案,但在图2b、3b、4b、5b和6所示的本发明替代实施方案中,可以在各共轭有机淀积物20上,淀积多个第一(14)和第二(22)电极。 Although FIG. 2a, 3a, 4a and 5a and 14 illustrate an embodiment having a first electrode of the second electrode 22, but in FIG. 2b, 3b, 4b, 5b and 6 of the present invention shown in an alternative embodiment, conjugated organic material can be deposited in each of the 20, depositing a first plurality (14) and second (22) electrodes. 应注意,尽管图2b、3b、4b和5b和6的示图没显示多个第一电极14,但可以与多个第二电极22交叉形成(在图2b、3b、4b、5b和6的侧视图可以看到)。 It is noted that, although FIG. 2b, 3b, 4b and 5b and 6 illustrate did not display a plurality of first electrode 14, but may be formed with a second plurality of interdigitated electrodes 22 (in FIG. 2b, 3b, 4b, 5b and 6 side view can be seen).

在图6的实施方案中,多个第一电极14(从图中看不到)被喷墨印刷到基片12上。 In the embodiment of FIG. 6, the plurality of first electrodes 14 (not seen in Figure) is inkjet printed onto the substrate 12. 然后,利用旋涂或其它常规施加方法,在多个第一电极14上,形成共轭有机缓冲层16。 Then, by spin coating or other conventional application methods, the plurality of first electrodes 14, to form a conjugated organic buffer layer 16. 然后,在共轭有机缓冲层16上,喷墨印刷多个第二电极22。 Then, on the conjugated organic buffer layer 16, the plurality of second electrodes 22 ink jet printing.

在图7a和7b所示的本发明替代实施方案中,为了讨论的目的,只示出了一个共轭有机淀积物20,共轭有机淀积物20包括导电或电荷传递材料。 The present invention shown in FIGS. 7a and 7b alternative embodiments, for purposes of discussion, only shows one conjugated organic deposit 20, the conjugated organic deposit 20 comprises a conductive material or charge transfer. 由于与电极材料相比,导电/电荷传递共轭有机淀积物20具有较好的电荷注入特性,所以在电压加于第二电极22和第一电极14上时,电流24在第二电极22和第一电极14间流动,并通过只在其上印刷了导电/电荷传递共轭有机淀积物20的共轭有机缓冲层16。 As compared with when the electrode material, the conductive / charge transfer conjugated organic deposit 20 having good charge injection characteristics, the voltage applied to the second electrode 22 and the first electrode 14, second electrode 22 in the current 24 and flows between the first electrode 14, and the organic deposit only by printing the conductive / charge transfer in which the conjugated organic buffer layer 16 is 20.

在各种有机半导体器件中,电致发光(EL)器件尤其引人注目,这是由于它们在未来光源、单或多色显示器、LELs、多色发射器件、贺卡及低和高密度信息显示器方面的潜在应用。 In various organic semiconductor devices, electroluminescence (EL) device is especially attractive, because of their level in the coming light, mono- or multicolor display, LELs, multicolor emitting device, greeting cards, and low and high density information displays the potential applications. 所以,在另一替代实施方案中,第一电极14和基片12是透明的,共轭有机缓冲层16包括发光材料。 Therefore, in another alternative embodiment, the first electrode 14 and the substrate 12 is transparent, the conjugated organic buffer layer 16 comprises a light emitting material. 在这些实施方案中,通过共轭有机缓冲层16的电流24引起从共轭有机半导体器件10的发光32。 In these embodiments, the organic buffer layer to cause light emission from conjugated conjugated organic semiconductor device 32 of Current 24 10 16.
