THz wave (300GHz–3THz, T-ray) applications in scientific and engineering applications have drawn tremendous research efforts recently. In contrast to X-ray, it is a non-ionized light source for non-invasive detection of biological tissues without the concern of much radiation exposure. Thus it is believed as an emerging technology for next generation medical imaging system. Additionally, T-ray is capable to penetrate clothing and many (non-metallic) packaging materials. It opens up unique screening possibilities for detection of concealed weapons, chemicals and biological agents, tumors, cavities, and also opportunities for short range radars and secured high data rate wireless communications. As projected by ITRS, the fT and fmax of CMOS (Complementary Metal Oxide Silicon) integrated circuits (IC’s) technologies will reach the regime of 0.5 THz by 2015. The great advancements have enabled silicon technology as an alternative means for realization of economical THz systems. The objective goal of this project is to build up THz medical imaging system through the developing of THz core devices as well as establishing the measurement techniques for THz spectrum. This project leverages efforts and experts from aspects of optical imaging system, circuits and packaging design, to fundamental physics researchers. It incorporates 5 sub-projects (1) Construction and development of a THz medical imaging system (2) Terahertz measurement techniques (3) THz signal generator design in CMOS technology (4) Terahertz CMOS RF imaging detector array integrated system (5) MEMS-based THz guiding structure design. The action items are briefly described as follows. Sub-project (1) will setup the imaging system and define system specifications for other subprojects. Sub-project (2) focuses on the development of THz measurement techniques. As THz spectrum is beyond the scope of most of the instrument vendors, it is essential to build up in-house facilities for system and device characterization. Sub-project (3) targets at the development of THz signal generator in CMOS technology for both the imaging screening and local oscillators for THz detectors. Sub-project (4) develops THz device modeling, THz system EDA design flow, and scalable detector array system IC. Sub-project 5 provides carrier platform, MEMs based guiding structure, and antenna array for packaging and system integration. In collaboration with all the sub-projects, all integrated circuits will be designed and fabricated using a 65nm (or more advanced) CMOS process. The developed core devices will be further integrated for system verifications. Most important of all, the participated groups will share all the research resources, including hardware, software, and common facilities. In addition to pursue technology excellence, this project also aims at cultivating talents with varieties of expertise to enable the advancement of Taiwan industry. C011
