Abstract: Container structures for use in integrated circuits and methods of their manufacture without the use of mechanical planarization such as chemical-mechanical planarization (CMP), thus eliminating CMP-induced defects and variations.

The localized masking is accomplished through differential exposure of a resist layer to electromagnetic or thermal energy. The container structures are adapted for use in memory cells and apparatus incorporating such memory cells, as well as other integrated circuits.
