Patent ID: 7344913

Claim:
A method of making an organic memory cell comprising: providing a first electrode; forming a passive layer comprising a conductivity facilitating compound over the first electrode; forming an active layer over the passive layer using a spin-on technique, the spin-on technique comprising applying a mixture of i) from about 0.1% to about 75% by weight of an organic semiconductor material, ii) from about 0.1% to about 20% by weight of an inorganic metal salt, and iii) from about 25% to about 99.9% by weight of at least one solvent selected from the group consisting of glycol ether esters, glycol ethers, furans, and alkyl alcohols containing from about 4 to about 7 carbon atoms; contacting the active layer with hydrogen sulfide gas to permit hydrogen sulfide to react with the inorganic metal salt to form a metal sulfide; and providing a second electrode over the active layer.
