  • Publication number: 20140357072
    Abstract: A method of making a non-volatile memory (NVM) cell using a substrate having a top surface of silicon includes forming a select gate stack over the substrate. An oxide layer is grown on the top surface of the substrate. Nanocrystals of silicon are formed on the thermal oxide layer adjacent to a first side the select gate stack. The nanocrystals are partially oxidized to result in partially oxidized nanocrystals and further growing the thermal oxide layer. A control gate is formed over the partially oxidized nanocrystals. A first doped region is formed in the substrate adjacent to a first side of the control gate and a second doped region in the substrate adjacent to a second side of the select gate.

  • Publication number: 20120135596
    Abstract: A method for forming a semiconductor structure includes providing a semiconductor layer, forming nanocrystals over the semiconductor layer, and using a solution comprising pure water, hydrogen peroxide, and ammonium hydroxide to remove at least a portion of the nanocrystals. A ratio by volume of pure water to ammonium hydroxide of the solution may be equivalent to or less than a ratio by volume of 10:1 of pure water to ammonium hydroxide when ammonium hydroxide has a concentration of 29% ammonia by weight. The step of using the solution to remove the at least a portion of the nanocrystals may be performed at a temperature of 50 degrees Celsius or more.

  • Patent number: 7799634
    Abstract: Nanocrystals are formed over an insulating layer by depositing a semiconductor layer over the insulating layer. The semiconductor layer is annealed to form a plurality of globules from the semiconductor layer. The globules are annealed using oxygen. Semiconductor material is deposited on the plurality of globules to add semiconductor material to the globules. After depositing the semiconductor material, the globules are annealed to form the nanocrystals. The nanocrystals can then be used in a storage layer of a non-volatile memory cell, especially a split-gate non-volatile memory cell having a select gate over the nanocrystals and a control gate adjacent to the select gate.
