发明名称 Method for fabricating dishing free shallow isolation trenches
摘要 A fabrication process for manufacturing integrated circuits with isolation trenches. The process includes the use of two nitride layers and an oxide layer formed by high density plasma oxidation, to provide isolation trenches free of dishing. The isolated regions are useable for fabrication microelectronic circuit devices, such as MOS transistors or flash memory devices.
