摘要:
A manufacturing method for stacked, non-volatile memory devices provides a plurality of bitline layers and wordline layers with charge trapping structures. The bitline layers have a plurality of bitlines formed on an insulating layer, such as silicon on insulator technologies. The wordline layers are patterned with respective pluralities of wordlines and charge trapping structures orthogonal to the bitlines.

A memory and a manufacturing method thereof are provided. The memory includes a dielectric layer, a polysilicon layer, a first buried diffusion, a second buried diffusion, a charge storage structure and a gate. The polysilicon layer is disposed on the dielectric layer and electrically connected to at least a voltage. The first buried diffusion and the second buried diffusion are separately disposed in the surface of the polysilicon layer. The charge storage structure is disposed on the polysilicon layer and positioned between the first buried diffusion and the second buried diffusion. The gate is disposed on the charge storage structure.

摘要:
An air tunnel floating gate memory cell includes an air tunnel defined over a substrate. A first polysilicon layer (floating gate) is defined over the air tunnel. An oxide layer is disposed over the first polysilicon layer such that the oxide layer caps the first polysilicon layer and defines the sidewalls of the air tunnel. A second polysilicon layer, functioning as a word line, is defined over the oxide layer. A method for making an air tunnel floating gate memory cell is also disclosed. A sacrificial layer is formed over a substrate. A first polysilicon layer is formed over the sacrificial layer. An oxide layer is deposited over the first polysilicon layer such that the oxide layer caps the first polysilicon layer and defines the sidewalls of the sacrificial layer. A hot phosphoric acid (H3PO4) dip is used to etch away the sacrificial layer to form an air tunnel.
