Development of Organic Semiconductor Material Technology Development of Organic Semiconductor Material Technology The field of screen printing is facing huge challenges, and the screen printing industrial system is undergoing unprecedented changes.The author has written many articles about the vitality and development potential of screen printing technology in new fields, and also conveyed some common development laws in other industrial technology fields.This law of development needs to be respected by everyone. The single technology game has ended. In the next development model, it is necessary to open the boundaries of the screen printing industry, explore upstream and downstream at the same time, combine the original advantages, and step out of the printing process. Build a complete value chain and show the picture of the future industry.

Whether to do a career is a limited game or an unlimited game. This is a question. The limited game is to complete the movement within the industry, and the infinite game is to take all factors related to the career into consideration. The progress of the relevant technology industry and the Internet Printing has nothing or little to do with it. That was just in the past. Nowadays, career opportunities often appear on the margins.Every different perspective breeds new opportunities.
The screen printing industry is actually an application-oriented technical engineering system. It has the ability to step out of its own boundaries and incorporate such an industry into more high-tech industries. This is a promising path.Technology is infinitely expandable, and together with the technology industry, the application of screen printing is infinitely expandable.The possibilities of technology are an ecosystem, but if no one promotes it initially, these ecosystems cannot be established.All great undertakings and implemented technological realities are driven by people.
After careful analysis, we can find that there are several basic material technologies that can cause industrial revolution in the future that are connected to screen printing technology.Among them, the basic materials that already have global industrial advantages are organic semiconductors and advanced carbon-based new materials.
The 'entanglement' between screen printing technology and electronic technology is deep. The progress of advanced electronic material technology will usher in a new spring for the global electronic printing market.The processing of organic semiconductors can be carried out at room temperature, which is a good opportunity for the screen printing process.
In fact, the screen printing industry is no stranger to organic semiconductor materials. A few years ago, 'Screen Printing' magazine covered such a topic.Technology development has its own rules. When different types of technology develop to a level of complexity that can be transferred, integration between technology systems will occur.With the establishment of a network-based knowledge management system, industrial applications can already see that the upstream technical systems and basic scientific research results have begun to gradually mature, and the downstream consumer-oriented application systems are also around the corner.The screen printing industry needs to march into these future emerging areas and occupy a place.

Organic electronics is a relatively new subject and is also the focus of global basic materials research and development.At that time, three scientists mixed iodine into the organic polyacetylene material and discovered the conductive polymer. This revolutionary discovery did not cause much sensation at the time, but the possibility and market prospects of this technology is huge.The potential of organic matter as a semiconductor has attracted widespread attention from scientists. It can be said to be the basic technology for realizing the intelligence of all things in products, thus giving rise to a new branch of organic electronics.Organic substances are used as semiconductors or even conductors to prepare electronic devices and electronic circuits to replace traditional electronic products based on part of silicon. Taking advantage of the large-scale and low-cost synthesis of organic substances, we can realize the mass manufacturing of electronic smart products. As an industry 4.0 and material Application technology of networking technology.Obviously, this manufacturing process cannot be without the participation of screen printing technology. In current global laboratories, the main technologies used in the experiment and molding of organic semiconductor material products are screen printing technology and digital inkjet technology.Among them, screen printing has relatively low technical requirements for ink form, and its tolerance is superior to inkjet technology, so it occupies a dominant position.It is expected that a large amount of capital will enter this field in the future.
In 2000, Hegel and other original discoverers won the Nobel Prize for conducting polymers.Since then, the practical research and development of plastic semiconductor materials has been a hot topic.Compared with semiconductors such as silicon, organic semiconductors are low-cost and have price advantages. They can be incorporated into the fine chemical industry, that is, the synthesis of some fine chemicals. This is a different technical path from the silicon industry, and smaller companies can also participate. The production of new materials, and the provision of silicon crystals, requires massive investment and high-precision manufacturing processes.Silicon crystal is a solid and follows all the processes of solid manufacturing. Organic semiconductors can be made into oil and ink states, and the manufacturing process has a relatively good degree of freedom. Organic materials can be printed using the full liquid method to prepare large-area circuits, further increasing the process cost. reduce.The ultra-light weight and innate bendability and stretchability of organic materials enable the realization of flexible electronic devices, which is crucial for future wearable and portable electronic products.In laboratories around the world, there is competition for R&D talents in organic conductive polymers, and large companies hope to achieve breakthroughs in such fields.Stanford University and the Massachusetts Institute of Technology in the United States have gathered R&D teams with the world's top talents in this field. Chinese universities and scientific research institutions are also increasing their efforts in the research and development of basic high-performance semiconductor materials.Among them, Li Hongxiang’s research group at the Shanghai Institute of Organic Chemistry, Chinese Academy of Sciences has made a series of progress in p-type and n-type high-performance organic semiconductor materials.
People outside the industry see organic semiconductors as actually a new type of plastic that has the function of a semiconductor and can be used to print the electronic circuits and functional electronic products we need in the flat field.We know that traditional semiconductors include germanium, silicon, tin, and many compounds composed of nearby elements such as ammonium arsenide and antimonide. These are all inorganic substances. It is difficult for people to imagine that an organic substance can also be used as a semiconductor, because in People have the impression that plastic can only be a good insulator.There are many types of organic semiconductors, and their performance varies. For applications, just choose more mature technical materials.
For the screen printing industry and the digital printing industry, it is not necessary to have a thorough understanding of the basic materials, including the precise synthesis process, it is enough to know.In fact, knowledge between majors can now be integrated, but the professionalism of knowledge has become more and more sophisticated. The combination of mature technologies is an application-oriented technical engineering principle.Therefore, when we use this technical system, we try our best to use materials that have been tested in practice to develop application products.
Screen printers are no stranger to cheap electronic circuit printing on flexible substrates. Printing inks such as silver paste and carbon paste are now commonly used.One of the current hot spots in the global electronics industry is that not only electronic circuits need to be made using printing technology, but also the transistor components in the circuit need to be made using printing technology. This is actually the application system we are talking about in this article. .
This kind of organic transistor component, which can be directly produced using a combination of various printing processes, can produce cheap and practical electronic products.Organic transistors have important applications in flexible displays, electronic labels, sensors, etc. due to their light weight, large-area preparation, and application on flexible substrates.Future intelligent robots and artificial intelligence technology products will require a large number of high-performance electronic devices, and high-performance organic semiconductor materials are the core components of organic transistors and the basis for the application of organic transistors.It is a trend for a large number of electronic products to be copied using full printing processes, which is a huge opportunity for the screen printing industry.
Although in the short-term technology outlook, organic semiconductor materials are not yet comparable in performance to inorganic semiconductor materials such as silicon, their application value can be reflected in different fields.Compared with inorganic semiconductors, organic semiconductors have their own technical advantages. From the application side, we do not need to compare who is better and who is worse.Instead, it is used in different fields to create corresponding products.
Currently, the research and development of all-organic semiconductor technology is in competition. Judging from the number of patent applications, the total number of patent applications for polymer materials worldwide is 370. These are basically based on innovations in basic materials. Among them, small molecule organic semiconductors The material has gradually developed since the first patent application was submitted in 2003, and there was a significant increase from 2011 to 2013.Before 2010, the number of patent applications for polymer materials was relatively small, but there was an explosive growth in 2010.From 2010 to 2013, the number of patent applications for polymer materials accounted for 87% of the total number of applications in recent years.Chemical synthesis methods can be used to prepare complex organic semiconductors, and organic semiconductors with corresponding properties can be controlled and obtained based on increasingly mature molecular designs, so that the types of materials can reach So, what can screen printers and technology developers do in the field of organic semiconductors? What? In the future prediction of technology for 2030, electronic contact lenses can directly achieve augmented reality.In the future, such technology will rely on the transparency of organic semiconductors to prepare fully transparent devices and realize window-based electronic products.These products that will become mainstream products in the future have not been manufactured yet. With the technical layout here, leading companies in the screen printing industry can fully conduct in-depth research and development to carry out application innovation for the future.As an industry owner, we need to open our closed horizons towards the future of technology and apply screen printing technology to more advanced manufacturing industries in the future.
