and other products. Paz de Araújo is the founder of RAMTRON an
Symetrix
Corporations. He identified SrBi2Ta203 (SBT), the ferroelectric material used in the most advanced FeRAMs and which resolves the fatigue problem and fabrication difficulties in memory chips, ensuring that stored information is retained. He and his colleagues were the first to use ferroelectric thin films as high-k capacitors for cellular phones, integrated into a set of gallium arsenide chips. The resulting devices were 50 times smaller and drew a fraction of the power of their predecessors. Working with scientists at Matsushita Electric Industry Company in Japan, he adapted SBT technology to contactless smart cards that permit information to be continuously upgraded during use. Paz de Araujo is the editor o
Integrated Ferroelectrics
and chairman of the International Symposium on Integrated Ferroelectrics. He has edited two books on integrated ferroelectrics and is the author of several papers on ferroelectrics.
