Method and structure for integrating capacitor-less memory cell with logic

Abstract:

Methods for fabricating integrated circuits include fabricating a logic device on a substrate, forming an intermediate semiconductor substrate on a surface of the logic device, and fabricating a capacitor-less memory cell on the intermediate semiconductor substrate. Integrated circuits with capacitor-less memory cells formed on a surface of a logic device are also disclosed, as are multi-core microprocessors including such integrated circuits.

Abstract(Chinese):
