In the past 50 years, humankind has experienced unprecedented progress in information technology (IT) from computers to mobile communication. The progress has been based on the invention of the silicon (Si) technology and consecutive scaling down of transistors from 1mm scale to 10nm following Moore’s law. On the other hand, life has been evolving on earth for billions of years. The molecular equivalence to Si in IT technology is carbon (C) and the size of the molecular structure in life such as DNA and peptide has a size in the order of 10nm.

There are similarities in the basic underlying physics associated with the biochemistry (related to life) and semiconductor physics; that is the ‘tunneling’ of electrons between two materials [1]. In this talk, I will show some typical examples of similarities: such as those processes taken place in the photosynthesis, glycolysis and NAND flash memory.

Understanding of the electronic processes in these two areas has led us to the invention of H+ electrochemistry [1] in the MOS type system and electrical pulsing techniques [2],[3] to the electrical biosensor, both developed at Seoul National University, Korea. We are now applying the pulsing technique to sensing the DNA as the biomarker of the Denge virus in collaboration with the IMEN (Institute of Microengineering and Nanoelectronics) of Malaysia.

Young June Park received the B.S. and M.S. degrees in electrical engineering from Seoul National University, in 1975 and 1977, respectively. He received a Ph.D. degree in electrical engineering from University of Massachusetts, USA, in 1983. From 1983 to 1988, he worked for IBM, East Fishkill, NY, and LG Semiconductor, Seoul, as a research staff member. In 1988, he joined Seoul National University as a faculty member and has contributed to education, establishment of semiconductor lab, consulting to companies (such as the R&D director in SKhynix) as well as to the government of Korea. His research areas of interest include the nano semiconductor device physics, reliability and bio molecular sensing using semiconductor devices.
