摘要： A polysilicon-based floating gate is formed so as to be resistant to oxidation that occurs during multiple thermo-cycles in fabrication. Accordingly, edge erase times in NOR-type memory devices may be minimized. Additionally, manufacture of oxidation resistant floating gates reduces variations in edge erase times among multiple NOR-type memory devices. A layer of amorphous silicon is deposited over a silicon substrate by directing a mixture of silane and a phosphene-helium gas mixture at the surface of the silicon substrate. Later, N+ ions are implanted into the amorphous silicon. The amorphous silicon layer is then etched so as to overlap slightly with regions that will later correspond to the source and drain regions. Next, a lower oxide layer of an ONO dielectric is deposited and the device is heated. A thermo-cycle is eliminated by heating the amorphous silicon during formation of the oxide layer rather than immediately following its deposition. Later, the nitride and oxide layers of the ONO dielectric, a second polysilicon layer, a tungsten silicide layer, and SiON layers are successively formed.

摘要： Polystringers that cause NAND-type memory core cells to malfunction are removed. A SiON layer, tungsten silicide layer, second polysilicon layer, ONO dielectric, and first polysilicon layer are successively removed from between NAND-type flash memory core cells leaving ONO fence that shields some first polysilicon layer material from removal. Next, the device is exposed to oxygen gas in a high temperature environment to oxidize the surface of the device, and in particular to remove the polystringers.

摘要： Provided are test vehicles for evaluating various semiconductor materials. These materials may be used for various integrated circuit components, such as embedded resistors of resistive random access memory cells. Also provided are methods of fabricating and operating these test vehicles. A test vehicle may include two stacks protruding through an insulating body. Bottom ends of these stacks may include n-doped poly-silicon and may be interconnected by a connector. Each stack may include a titanium nitride layer provided over the poly-silicon end, followed by a titanium layer over the titanium nitride layer and a noble metal layer over the titanium layer. The noble metal layer extends to the top surface of the insulating body and forms a contact surface. The titanium layer may be formed in-situ with the noble metal layer to minimize oxidation of the titanium layer, which is used as an adhesion and oxygen getter.
