Biochip, that is a fusion of BT/IT/NT, is the fundamental technology of bio-engineering in Post-genome Era. It is not only the tool to analyze the huge bio-informations but also the technology necessary for screening of new medicine and medical examination. Except some technological fields, biochip area has a good chance of occupying advantageous position in the world technology community by early aggressive investment, because a new access to this technology is possible without a past imitation process. This study is to analyze the trend of development of domestic and foreign biochip technology and its current market status. Finally it presents some suggestions for the government policy considering the possibility of its development in Korea.
