Publication number: 20070090343Abstract: A system and method are disclosed for processing an organic memory cell. An exemplary system can employ an enclosed processing chamber, a passive layer formation component operative to form a passive layer on a first electrode, and an organic semiconductor layer formation component operative to form an organic semiconductor layer on the passive layer. A wafer substrate is not needed to transfer from a passive layer formation system to an organic semiconductor layer formation system. The passive layer is not exposed to air after formation of the passive layer and before formation of the organic semiconductor layer. As a result, conductive impurities caused by the exposure to air do not occur in the thin film layer, thus improving productivity, quality, and reliability of organic memory devices. The system can further employ a second electrode formation component operative to form a second electrode on the organic semiconductor layer.Type: ApplicationFiled: October 21, 2005Publication date: April 26, 2007Applicants: SPANSION LLC, Advanced Micro Devices, Inc.Inventors: Nicolay Yudanov, Igor Sokolik, Richard Kingsborough, William Leonard, Suzette Pangrle, Nicholas Tripsas, Minh Ngo

Publication number: 20070029604Abstract: The present invention facilitates dual bit memory devices and operation of dual bit memory device by providing systems and methods that employ a relatively thin undoped TEOS liner during fabrication, instead of a relatively thick TEOS layer that is conventionally used. Employment of the relatively thin liner facilitates dual bit memory device operation by mitigating charge loss and contact resistance while providing protection against unwanted dopant diffusion. The present invention includes utilizing a relatively thin undoped TEOS liner that is formed on wordlines and portions of a charge trapping dielectric layer. The relatively thin undoped TEOS liner is formed with a thickness of less than about 400 Angstroms so that contact resistance and charge loss are improved and yet providing suitable protection for operation of the device. Additionally, the present invention includes foregoing with an undoped TEOS liner altogether.Type: ApplicationFiled: October 12, 2006Publication date: February 8, 2007Inventors: Ning Cheng, Minh Ngo, Hirokazu Tokuno, Lu You, Angela Hui, Yi He, Brian Mooney, Joan Yang, Mark Ramsbey
