Abstract

Procedimento per fabbricare un condensatore a cella di DRAM di tipo multicamere avente un'elevata capacità entro un'area limitata. Una prima area concava (54) dell'elettrodo di immagazzinamento (72) è formata tramite una pellicola di ossido (46) e uno strato a scarificazione. Un distanziatore isolante (58) è formato nella prima area concava (54). Quindi, un primo e secondo strati conduttivi (48, 60) sono formati sul substrato (26) e porzioni superiori degli strati conduttivi sono rimosse consecutivamente così da formare un condensatore avente una pluralità di aree concave.
