摘要: Arrangement of capacitors which, without taking up an additional area in the semiconductor substrate, have increased capacitance compared with conventional DRAM memory cells. The arrangement according to invention is based on a combination two or more separately arranged individual substrate form one other above other. In this case, outer capacitor encloses at least plurality inner. substantial part upper lies lower capacitor. A method for fabricating also described.
