In order to keep technical competitive advantage, most companies have an ongoing need of competent technical professionals in research and development (R&D). To possess sufficient capable R&D technical professionals, companies must effectively help them to identify and to cultivate their competencies. Attempting to develop high-tech manpower quality indicators for R&D technical professionals of integrated circuit (IC) manufacturers in Taiwan, this study applied competency theory and investigated 709 valid respondents who are members of Taiwan Semiconductor Institute. The study results can serve as the groundwork for advanced studies in designing meaningful programs for training, development, and career planning, as well as for recruiting qualified R&D technical professionals.
