中文摘要：	半导体技术作为电子信息产业的基石技术，被广泛应用于现代社会各个领域，其技术水平的高低已成为衡量一个国家技术实力的重要标志，半导体产业更是支撑经济社会发展的战略性、基础性和先导性产业。当今世界正经历一场以人工智能、5G技术、新能源技术等高新技术为核心的产业革命，半导体产业作为这场产业革命的重要组成部分，正处于新一轮的深度调整节点，世界各国纷纷布局半导体产业，力争在新的产业格局中占据有利位置，我国半导体产业面临前所未有的机遇与挑战。然而我国的半导体产业仍然存在着各种问题，在国际竞争中处于劣势，因此，通过对半导体专利的研究，识别我国半导体产业发展现状与存在的问题，对于提升我国半导体产业技术水平与国际竞争力具有十分重要的意义。 本文使用文献计量法和社会网络分析法，从半导体专利申请现状、半导体专利合作网络、半导体专利关键技术三个方面对半导体专利进行了分析。其中，在对专利申请现状的分析中，发现半导体技术处于技术成熟期，中、日、美、韩为主要专利申请国，三星公司等企业为全球范围内的主要专利权人。在对专利合作网络的分析中，发现专利合作网络密度普遍较低，通过节点中心度、m-核分析识别了国内外重要发明人、发明团队、科研院所、产学研合作团体，并对发明团队与合作团体的特征与拓扑结构展开了分析。在对关键技术的研究中，识别出半导体图像传感器、化学机械研磨技术等17项关键技术，而中国在光刻技术、化学气相沉积技术等关键技术领域存在劣势，通过专利主路径分析，挖掘了化学气相沉积技术、化学机械研磨技术、光刻技术这三项我国劣势关键技术的国内外核心专利、技术发展路径，并对关键技术的研究结果进行了讨论。基于以上研究结果，本文从专利布局、技术研发、产业发展三个方面，提出了加强科研成果转移、促进跨地区产学研合作，优先发展第三代半导体技术等建议。
英文摘要：	As the cornerstone technology of the modern electronic information industry, semiconductor technology is widely used in various fields of modern society. The technical level of semiconductor technology has become an important symbol for measuring the technological strength of a country, the semiconductor industry is a strategic fundamental and pioneering industry that supports economic and social development. The world today is experiencing an industrial revolution centered on high-tech such as artificial intelligence, 5G technology, and new energy. As an important part of this industrial revolution, the semiconductor industry is in a new round of in-depth adjustment. China's semiconductor industry is facing unprecedented opportunities and challenges as countries around the world are developing the semiconductor industry one after another, striving to occupy a favorable position in the new industrial pattern. However, China's semiconductor industry still has various problems and is at a disadvantage in the international competition of the semiconductor industry. Therefore, through the study of semiconductor patents, identifying the current situation and problems in the development of China's semiconductor industry is of great importance to enhance the technological level and international competitiveness of China's semiconductor industry. This paper uses bibliometric method and social network analysis method to analyze semiconductor patents from three aspects: semiconductor patent application status, semiconductor patent cooperation network, and key technologies of semiconductor technology. In the analysis of the current situation of patent applications, it is found that semiconductor technology is in a mature stage of technology lifecycle, China, Japan, the United States, and South Korea are the main patent application countries, and companies such as Samsung are the main patent holders. In the analysis of patent cooperation network, it is found that the density of patent cooperation network is generally low, through node centrality and m-core analysis, important inventors, invention teams, scientific research institutes, and industry-university-research cooperation groups have been identified. The characteristics and topology of invention teams and cooperative groups are analyzed too. In the research of key technologies, 17 key technologies such as semiconductor image sensor and chemical mechanical polishing technology are identified, China has disadvantages in key technology fields such as lithography technology and chemical vapor deposition technology. Then, through the patent main path analysis, the domestic and foreign core patents and technology development paths of chemical vapor deposition technology, chemical mechanical polishing technology, and lithography technology are identified, and the research results of key technologies are discussed. Based on the above findings, this paper proposes to strengthen the transfer of scientific research results, promote cross-regional cooperation between industry, academia and research, and prioritize the development of third-generation semiconductor technology, etc.
