The fields of research in the Nano-Integrated Circuit Engineering Program of National Cheng Kung University are focused on 1) nanoelectronic device design and technology and 2) sensors. As semiconductor devices continue to shrink, mainly for cost reduction in industry, many issues have continuously surfaced. Besides manufacturing challenges, ever increasing transistor density and computation have raised the concern on power consumption. To expedite further nanoelectronic development, especially for growing mobile market, low power electronics are on demand, which requires novel devices to fulfill the low power strategy while the performance is not compromised. This Nano-IC Program has developed several novel green electronic devices. Another field of sensors has just been started. We have worked on novel materials including promising 2D materials for photo detectors. Other experiments of nanoelectronic devices for general sensor applications are under progress.
