Abstract (en)

[origin: WO2009005699A1] A method of forming a memory cell is provided that includes (1) forming a first conductor (206) above a substrate; (2) forming a reversible resistance-switching element (202) above the first conductor using a selective growth process; (3) forming a diode (204) above the first conductor; and (4) forming a second conductor (208) above the diode and the reversible resistance-switching element so as to obtain a crosspoint memory device. The switching element can also be steered by a TFT. The switching element contains a difficult to etch material, e.g. TiO2, and is formed without etching this material by means of oxidising another material, e.g. Ti or TiN.
