摘要:
Memories and their formation are disclosed. One such memory has a first array of first memory cells extending in a first direction from a first surface of a semiconductor. A second array of second memory cells extends in a second direction, opposite to the first direction, from a second surface of the semiconductor. Both arrays may be non-volatile memory arrays. For example, one of the memory arrays may be a NAND flash memory array, while the other may be a one-time-programmable memory array.

Embodiments of the invention pertain to vertical memory structures. Embodiments of the invention describe memory nodes comprising two memory cells on opposing sides of a vertical channel separating a source region and a drain region. Embodiments of the invention may utilize floating gate NAND memory cells, polysilicon diodes, MiM diodes, or MiiM diodes. Embodiments of the invention may be used to form flash memory, RRAM, Memristor RAM, Oxide Ram or OTPROM.

Methods of forming conductive elements, such as interconnects and electrodes, for semiconductor structures and memory cells. The methods include forming a first conductive material and a second conductive material comprising silver in a portion of at least one opening and performing a polishing process to fill the at least one opening with at least one of the first and second conductive materials. An annealing process may be performed to form a mixture or an alloy of the silver and the material. The methods enable formation of silver containing conductive elements having reduced dimensions (e.g., less than about 20 nm). The resulting conductive elements have a desirable resistivity. The methods may be used, for example, to form interconnects for electrically connecting active devices and to form electrodes for memory cells. A semiconductor structure and a memory cell including such a conductive structure are also disclosed.

摘要:
Methods of forming an array of memory cells and memory cells that have pillars. Individual pillars can have a semiconductor post formed of a bulk semiconductor material and a sacrificial cap on the semiconductor post. Source regions can be between columns of the pillars, and gate lines extend along a column of pillars and are spaced apart from corresponding source regions. Each gate line surrounds a portion of the semiconductor posts along a column of pillars. The sacrificial cap structure can be selectively removed to thereby form self-aligned openings that expose a top portion of corresponding semiconductor posts. Individual drain contacts formed in the self-aligned openings are electrically connected to corresponding semiconductor posts.
