摘要: A process of forming a device with nanoclusters. The process includes forming nanoclusters (e.g. silicon nanocrystals) and forming an oxidation barrier layer over the nanoclusters to inhibit oxidizing agents from oxidizing the nanoclusters during a subsequent formation of a dielectric of the device. At least a portion of the oxidation barrier layer is removed after the formation of the dielectric. In one example, the device is a memory wherein the nanoclusters are utilized as charge storage locations for charge storage transistors of the memory. In this example, the oxidation barrier layer protects the nanoclusters from oxidizing agents due to the formation of gate dielectric for high voltage transistors of the memory.

摘要: A nanocrystal non-volatile memory (NVM) has a dielectric between the control gate and the nanocrystals that has a nitrogen content sufficient to reduce the locations in the dielectric where electrons can be trapped. This is achieved by grading the nitrogen concentration. The concentration of nitrogen is highest near the nanocrystals where the concentration of electron/hole traps tend to be the highest and is reduced toward the control gate where the concentration of electron/hole traps is lower. This has been found to have the beneficial effect of reducing the number of locations where charge can be trapped.
