将启发式方法作为技术范式的特征指示,以启发式方法的不连续性和稳定性为切入点,基于专利引证网络分析半导体制造领域技术范式和技术轨迹的发展和演化过程。从美国专利数据库中采集55 229项1976年至2006年授权的半导体制造领域的相关专利,从专利数据集NBER中查询得到专利引证关系,利用网络分析软件Pajek构建专利引证网络。应用搜索路径连接统计法和搜索路径节点对统计法计算专利引证路径的连接度,提取技术进化轨迹。以技术进化分叉为切入点,从技术进化轨迹连续性和稳定性的角度对半导体制造技术各个发展阶段进行界定。分析各个发展阶段中专利的适用范围、技术背景、解决方案等,从中提炼技术启发式方法,进而分析技术范式及其演化情况。最后对下一步的研究工作进行展望。

Heuristics is indicated as the characteristics of technological paradigm. Taking the discontinuity and stability of heuristics as entry points, the development and evolution of technological paradigms and technological trajectories of the semiconductor device manufacturing are analyzed based on patent citation network. Firstly, this paper collects 55 229 patents about semiconductor device manufacturing which was granted between 1976 to 2006 from the database of United States Patent and Trademark Office. Then it queries from the patent data set NBER to get patent citation relations and uses the network analysis software Pajek to build patent citation network. Secondly, search path link count and search path node pair is applied to calculate the connectivity weight of patent citation path, and the technological evolutionary trajectories are extracted. Thirdly, taking technological evolutionary bifurcations as entry points, the various development stages of semiconductor device manufacturing technology are defined from the perspective of evolutionary trajectories’ continuity and stability. This paper analyzes the scope, technological background and solutions of patents in these development stages, in order to refine technological heuristics and analyze the technological paradigms and their evolution. Finally, the further research work is prospected.
