Research Projects

Project 1

All of the large-scale integrated circuits in the semiconductor industry are manufactured by photolithographic techniques. Therefore, lithography which is used for the nanoscale fabrication has become a crucial technology to improve the chip performance. Photoresists are indispensable materials for the semiconductor industry. Their continuous development makes it possible to manufacture shapes of nanoscales, helping following the Moore's law. This project is to develop high performance photoresist to support the continuity of Moore's law.

Project 2 & 3

Based on deeper understanding insight of lithium ion batteries, to develop state-of-art technologies of high performance materials and battery technology for high energy density (500 Wh/kg), high safety and long cycling performance in vehicular applications. Focus on lithium metal anode, novel electrolyte and separator, high capacity cathode over 250 mAh/g with high practical density, and safety technology.
