This paper examines how technological and organisational changes are mediated through different means of mutually monitoring and collectively coordinating technological developments in the field of semiconductor manufacturing. As collective practices, both monitoring and coordinating aim at generating momentum in order to stabilise or redirect technological paths in organisational fields. The empirical analysis of innovation practices in the field of semiconductor manufacturing technology shows that the means of managing momentum, above all roadmaps, conferences, and R&D consortia, influence and transform the development of new technologies as well as the social relations within the organisational field. The transformative capacity of these means is elaborated conceptually using Giddens’ theory of structuration. 相似文献

This paper examines how innovation-related capabilities for production, design and marketing develop at the subsidiary level within multinational enterprises (MNEs). We focus on how subsidiary autonomy and changing opportunities to access external (host country) sources of capability contribute to the accumulation of specialist capabilities in five Taiwan-based MNE subsidiaries in the semiconductor industry. Longitudinal analysis shows how the accumulation process is subject to discontinuities, as functional divisions are (re)opened and closed during the lifetime of the subsidiary. A composite set of innovation output measures also shows significant variations in within-function levels of capability across our sample. We conclude that subsidiary specialisation and unique subsidiary-specific advantages have evolved in a way that is strongly influenced by the above factors. 相似文献

Hall efect is a well-known electromagnetic phenomenon that has been widely applied in the semiconductor industry.he quantum Hall efect discovered in two-dimensional electronic systems under a strong magnetic ield provided new insights into condensed mater physics,especially the topological aspect of electronic states.he quantum anomalous Hall efect is a special kind of the quantum Hall efect that occurs without a magnetic ield.It has long been sought ater because its realization will signiicantly facilitate the studies and applications of the quantum Hall physics.In this paper,we review how the idea of the quantum anomalous Hall efect was developed and how the efect was inally experimentally realized in thin ilms of a magnetically doped topological insulator. 相似文献

Scholars have identified the pivotal role that modularity plays in promoting innovation. Modularity affects industry structure by breaking up the value chain along technical interfaces, thereby allowing new entrants to specialize and innovate. Less well-understood is where modularity comes from. Firms seem to behave consistently with the theory in some settings, especially the information technology sector, but not in others, such as automobiles. Here we show how the government has a role to play in generating open interfaces needed for modularity, utilizing a case study of the semiconductor industry from 1970 to 1980. We show how the Defense Department's support for this effort aligned with its mission-based interest in semiconductors. We thus contribute a new source of open standards to the modularity literature, as well as a new analytical perspective to the public research funding literature. 相似文献

This paper evaluates the impact of basic and applied research on innovation in two industries. Whereas innovation in the pharmaceutical industry is closely tied to both basic and applied research, innovation in the semiconductor industry depends mainly upon applied research. Surprisingly, many firms perform little basic research, but they produce many innovations. Within each industry, firms pursue different R&D strategies: firms that emphasize basic research absorb more basic scientific knowledge than those that emphasize applied research. These findings suggest that future research must carefully consider how industry context and the composition of R&D mediate the relationship between research and innovation. 相似文献

Technological progress in an industry is enabled by the collective R&D efforts of suppliers, users and research organizations. In this study, we explore how the pattern of R&D collaboration within the industry community evolves over the technology life cycle. We propose that as the technology evolves from an initial emergence stage to subsequent stages of growth and maturity, there is a corresponding change in the opportunities and challenges confronting industry participants. This results in a shift not only in the relative propensities for internal and collaborative R&D, but also in the distribution of the different types of collaborative interactions involving research organizations, suppliers and users. The context for the study is the global semiconductor manufacturing industry from 1990 to 2010. During this period, the industry experienced exponential technological progress that was fueled by the deep ultraviolet (DUV) manufacturing technology. We draw upon a comprehensive archival dataset of more than 12,000 articles presented in industry technical conferences to analyze the pattern of collaborative R&D during the emergence, growth and maturity stages of the DUV technology. The observed trends in the semiconductor manufacturing industry point to intriguing shifts in the efforts and interactions among suppliers, users and research organizations as they collectively push the technology envelope forward. 相似文献
