Dynamic Measurement And Foresight Of The Scientific And Technological Inoovation In The Chip Domain

The United States launched a trade war with China to limit the export of chips to China,China’s ZTE Corporation,including a number of entities included in the U.S.export control list,the world’s major chip suppliers have also announced that they no longer supply Huawei or provide foundry services,China’s relevant enterprises are forced to transition from reliance on imports to independent research and development.All of the above shows that China’s lack of "core" less soul of the current situation,as the modern industrial "food",the chip is widely used in many emerging areas,leaving the chip industry support,the development of intelligent terminals will not be able to talk about.China’s chip technology has long been restricted,and is now facing the "neck" dilemma.To break through this dilemma,the key to rely on science and technology innovation,which is an inevitable choice,but also a realistic requirement.To grasp the current status of science and technology innovation in the chip field and predict the future opportunities of science and technology innovation in the chip field can provide reference for optimizing the research layout of the chip field,which can help further science and technology innovation in the chip field.Therefore,it is necessary to conduct an in-depth study on this issue.In view of this,this paper integrates scientometrics,social network analysis and link prediction methods to measure the current status of science and technology innovation in the chip field from typical innovation results in the chip field-papers and patents,and to predict future research themes and technology opportunities in the chip field from the current status to the future.The main research and findings of this paper are summarized as follows.First,to provide a comprehensive scientific innovation landscape in the chip field,this study uses bibliometrics and social network analysis to analyze spatial and temporal trends,collaboration characteristics,knowledge flows,and mainstream research paths through the global scientific paper output in the chip field.The results of the study show that the scientific paper output in the chip field shows a significant increasing trend;China overtook the United States as the world’s top output country in2017,and more basic research in the chip field is conducted by universities;the cooperation network shows a significant expansion trend,and the closest cooperation with Chinese mainland is with some neighboring countries/regions such as Japan,South Korea,and Chinese Taiwan is gradually expanding the degree of foreign cooperation,and the academic China is gradually expanding the degree of foreign cooperation and the pattern of academic-research cooperation is more obvious;Scientific research topics in the field of chips form three distinct clusters,mainly including research related to chip semiconductor materials,devices,and chip manufacturing technologies.Second,in order to provide a comprehensive technological innovation landscape in the chip field,this study uses patent measurement and social network analysis methods based on DII data to analyze spatial and temporal trends,cooperation characteristics,core organizations and key core technologies through the global patent output in the chip field.The results of the study show that the technological output in this field grew significantly between 1991 and 2008;Japan is the leader of technological innovation in this field,and a few countries/regions and organizations are in the main position of chip technology innovation;the cooperation network of organizations and institutions expanded significantly from 2001 to 2010,and the cooperation network formed obvious regional clusters;the core institutions in the field of chip technology are mainly companies from Japan,the followed by the United States and South Korea,TSMC of Chinese Taiwan is in a leading position in the world,and SMIC of Chinese mainland has shown its international status during 2001～2020,but its innovation power is high but its control is at a low level;the key core technologies in the chip field mainly include semiconductor or electrical solids-related devices and methods or equipment for handling them(H01L),the Housing or structural parts and manufacturing of electrical devices(H05K),and plating of metallic materials by physical or chemical methods(C23C),etc.Third,in order to predict future scientific and technological innovations in the field of chips,this study combines papers and patent data in the field of chips using social network analysis and linkage prediction methods.The results of the study indicate that European countries/regions will further cooperate and innovate in the field of basic chip research in the future,and the international activity of Taiwan,China in the field of basic chip research may further increase in the future;in institutional scientific cooperation in the future mainly contains institutions from the U.S.,China and Chinese Taiwan,and in institutional technical cooperation mostly institutions from Japan and they prefer to cooperate with The most likely future research themes in the chip field include semiconductor materials and their electrical properties,photolithography and etching technology,annealing technology,thin film process,and future technology opportunities mainly include soldering process of electronic components,image sensor chip device manufacturing,Semiconductor materials,chip packaging technology and the use of insulating materials in the packaging process,etc.To a certain extent,this paper complements and improves the previous research in the field of chips,and the research results also provide some reference significance for optimizing the layout of science and technology innovation and policy formulation in the field of chips.
