High-performance transistors study was supported by HKUST Department of Electronic and Computer Engineering Professor Liu Ji US -led research team invented , the earlier the Japanese Society of Applied Physics (JSAP) awarded Best Paper Award , this year's winners of the five teams , only one team in Japan outside the research team , but also the award inception in 1979 , the only award-winning Hong Kong and China research team . LIU Ji said the United States , the integrated circuit is mainly divided into two categories: First, silicon substrate , silicon , also known as Silicon (Silicon), is a chemical periodic table IVA category ; another is to use the Periodic Table IIIA and VA of different structure compound semiconductor materials, including aluminum, Ga (Gallium), indium (Indium), nitrogen, phosphorus and arsenic . The latter power than silicon substrate is high, but six inches in diameter an IC comparison silicon substrate is only 160 yuan each , the latter will have nearly $ 4,000. There are two types of integrated circuits may be the same floor , use cable ties , so that the cost increases, so the research community for decades are hoping to mix the three types of chemical materials , improve IC performance and power, but because the material does not match , has been not successful.HKUST use about $ 7.8 million worth of new equipment , and then at different temperatures and pressures of the " matching technology " will IIIA and VA of smoothing compound semiconductor material laid on different structures on silicon substrate , developed "high performance transistors ." Professor Liu pointed out that this IC transmission of electronic messages ten times faster than the silicon substrate , five times faster switching speed , more power Jiucheng, because the resistance is very low.The study by the Innovation and Technology Commission funded $ 18 million grant , the early Intel also has sponsorship. Liu said that currently the company set up by the World Semiconductor SEMATECH collaboration of research institutions ; She also refers to the world's first IC manufacturer Taiwan Semiconductor Manufacturing Company , but also " I went Chatting Chengri earn ."New inventions still as experimental products , so the cost is very high, requires manufacturers mass production before become general electronic components. Professor Liu said , is applying for patents, but will take several years, and papers have been published , can become a reference of the industry , estimated, may be available. Professor Liu pointed out that the next generation of researchers will be integrated optics , photonic replace electronic message across , just as the Internet transmission using fiber optics , which require higher laser technology , as there is already basic research, she estimated that two years can be brought to fruition , can improve over ten times the speed.
